This type of slide is in the aircraft's tailcone, and deploys after the tailcone is jettisoned by flight attendants, allowing for evacuation through the rear of the airframe. Some switches illuminate a ____ light when they are selected ON, to advise the crew that they are selected on and operating. The airline released a statement on . The IATA Airport Handling Manual 29th edition 2009 AHM 430 recommends that cabin access doors, ie passenger entrance and service doors, shall be operated by specially trained and qualified staff either inside or outside the aircraft, as instructed by the carrier. FUEL RECEPTACLE GROUND HEIGHT The 777F accommodates 27 standard pallets (96 by 125 inches; 2.5 by 3.1 meters) on the main deck. I know they had smaller engines, but surely that fuselage must've been really close to the ground?. On the face of the girt are instructions in large red lettering, and a handle with the word 'PULL' on it. Glucose 202 mg/dL \ nose up position due to the loss of landing gear), the slide will inflate normally but will also inflate several feet of additional slide to ensure the slide reaches the ground. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft Where immediate prohibition could cause significant health and safety or air safety risks, a deferred notice should be considered. Assuming a 3,730-U.S. gallon (14,120-liter) Accident, incident and crash related photos, Air to Air What is the condition of the Slide Arming Lever when the yellow arm plate is down and flush with the door? Door opening may be from inside or outside the aircraft but must be according to agreed procedures, to avoid any risk of accidental activation of the emergency chute. During transit or during maintenance visits, the aircraft doors may need to remain open for a number of reasons. 31 There are considerable limitations on the use and suitability of fall protection or work restraint equipment on aircraft and access platforms, including availability of attachment points that are rated for fall arrest (ie strong enough), actual height of work, whether there is sufficient height for a fall arrest system to work, the risk of hitting obstructions on the aircraft or vehicle during a fall, and the additional safety risks introduced in attaching and using harnesses. Window exits usually come in two configurations: Window exits are usually equipped with ditching or life lines. 7 Inspectors should be aware of existing industry guidance on opening aircraft doors: 8 When an aircraft door is opened this operation should preferably be performed with a wide platform which allows the door to open within the confines of the area protected by guardrails. Tests in 25-knot (46km/h) cross winds have shown these deployment systems to be very effective. It is proposed that catering of the new Airbus A380 can be carried out via upper deck doors. These procedures are usually placarded red on the slide, "For Ditching Use Only". This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. 38.70 m / 127 ft 0 in Overall length Depending on the size of your wheelchair/scooter, you may need to fold down your seatback in order for it to fit into the hold. 54 Where inspectors consider that an airline has responsibilities for safety such as procedures for opening aircraft doors, they should contact the Transportation Section and airline Head Office lead PI to check the national situation before taking any enforcement action. As the operation and design of such steps are part of the aircraft design, safe operation is dependent on training and competence of cabin crew. 61 Where inspectors find failings of management systems such as: 1) absence of suitable risk assessments; and/or, 2) inadequate arrangements for planning, organising, control etc; and/or, 4) employees are not following safe practices while opening/ closing aircraft doors; and/or, 5) there is a lack of suitably guarded access equipment; and/or. 2 Risks arise during maintenance of aircraft and during servicing and turnaround activities. Where attachment points are on guard rails, the rails must be of sufficient strength to withstand foreseeable forces. Who makes the plaid blue coat Jesse stone wears in Sea Change. TRUE/ FALSE. This is why when you are on a long flight, you will generally hear the captain say something like, Ladies and gentlemen, we have now reached our cruising altitude of 36,000 feet. Cabin Door Safety Strap More specifically, they are smaller than 25 inches. 6 Procedures and responsibilities for opening and closing aircraft doors often rely on cooperation and coordination between airline crew and ground handlers and should be included in the Turnround Plan and monitored by the Turnround Coordinator or Supervisor. However, for all the reasons mentioned above, this is mainly theoretical, and most commercial airplanes fly much lower than this. We have established the mechanical means by which aircraft doors are kept shut, but there is another aspect to consider. RE: 737 And 757 Ground Height #4708763 BY phollingsworth - Thu Feb 09, 2006 5:44 am Taking the FWD entry door sill height as an example. 14 Signals in use for door opening procedures vary at UK airports and between aircraft operators. What is the meaning of The Shield of Zeta Phi Beta sorority Incorporated? Aircraft flying government officials, Helicopters It works as an independent system, requiring no action other than arming the door as per normal standard operating procedures. This means that planes flying in opposite directions to each other are at least 1000 feet apart, so avoiding a possible collision and making for safer flights. Tejasvi Surya, national president of the BJP Yuva Morcha and the party's MP from Bengaluru South, allegedly opened the emergency exit of an IndiGo aircraft at Chennai airport on December 10 last year. It also minimizes the risk of accidental opening. Interpret F.N. Airliners.net is the leading community for discovering and sharing high-quality aviation photography. Flight 1603 went back to the gate and was taken out of service. **Laboratory Testing**\ This line will break if the airframe submerges, or can be disconnected with a pre-supplied knife or disconnect handle. After all, inward-opening cargo doors would reduce the available space for a freight aircraft's goods. Last month, a DHL Boeing 757's cargo door opened inflight in Germany, although, thankfully, the aircraft was able to land safely and without injuries to its crew. A centrifugal pump has the following dimensions: d2 = 42 cm, L = 5 cm, and $\beta 2=33^{\circ}$. Batteries that appear to be damaged or leaking may be removed and separately packaged by the carrier. The CO2 is used to slow down the rate at which the valve expends the gases. Another unique type of evacuation slide is found on the DC-9 family of aircraft and its successors the MD-80 and Boeing 717. Parking the plane. Should this also fail, standard operating procedures require the cabin crew to send passengers away from the door and to one that has a functioning escape slide. But small aircraft such as those flown by private pilots cannot fly this high, and usually do not go above 10,000 feet. Typically, aircraft fly around 35,000 or 36,000 feet above sea level. (Maximum CAA is tasked with investigating and enforcing under the Air Navigation Order (ANO) and with in-flight health and safety of crew under The Civil Aviation (Working Time) Regulations 2004. Safety features and proposed systems of work should be considered at the design stage to ensure that access equipment reduces the risk of falls so far as is reasonably practicable. Based in Norwich, UK. A slide/raft also functions as a life raft in a landing on water and therefore are required to include sea survival specific features such as; an erectable canopy, righting aids and survival packs containing items such as leak stoppers, paddles and flares. 13 If it is necessary to approach an unguarded edge to open or close a door, consideration should be given to additional protection such as door nets or personal fall protection (see paragraphs 31 - 34) where possible. Lower aircraft usually do not require such means of access, and have not been taken into account. White blood cell engulfing a bacterium is called __. The troposphere is usually said to finish at 36,000 feet. Everything from the Goodyear blimp to the Zeppelin, Night Photos A device can be used to prevent this problem. Pictures of great freighter aircraft, Government Aircraft During test flights this maximum is exceeded slightly to verify the that airplane remains safe should it have cause to ascend from that limit. The new slide/raft design was put forward to the International Air Transport Association (IATA), by Jack Grant, Qantas operations safety superintendent. Most airline passengers simply accept the fact that passenger jets fly very high. Where the steps have to be moved away before the aircraft door is closed, the door Must not be left unprotected and unsupervised at any time and the door must be closed without delay. While there are slight differences in the tail height of the different 747 variants, the differences are minor. Planes flying eastward, including northeast and southeast, will fly at odd altitudes, such as 35,000 feet. It also made inspection and work on the engines very easy. What is stopping a dangerous individual from opening the door inflight and potentially endangering the lives of the aircraft's occupants by forcing a rapid decompression? When the cover is released and the inflation system activated, the two aspirators come shooting out of the pack, gulping vast quantities of air and restrained only by the fabric tubes to which they are securely fastened. Short hops or longer routes - the E190 has the versatility to go the distance. Where is the control switch for the Standby Compass Light? The air becomes thinner as the altitude increases, and thin air creates less drag on the aircraft. But in fact, small aircraft generally fly much lower than that for a variety of other reasons. Assuming radial entry flow, determine the theoretical values for (a) the flow rate and (b) the power. Thankfully, the nature of physics renders this task impossible. 23 Clear procedures and means of communication should also be in place for removal of aircraft steps. Wind will determine how fast the aircraft is travelling across the ground on touchdown and how long it will need to brake thereafter. Seeing a gap in the market for a regional aircraft with mainline capabilities, we launched the E190. On the other hand, flying too high could have negative safety issues. We thank you for your support and hope you'll join the largest aviation community on the web. This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. Fuel This is all in addition to any maintenance that is specified by the manufacturer. For thee A320, what is the "Minimum Theoretical Pavement Width for a 180 degree turn? Latch-on guarantees fore and aft and vertical alignment of the loader bed with the aircraft doorway, when used in . Where doors are open and passengers are on board the aircraft it is particularly important that the doors are guarded either by a physical barrier or by a suitably trained crew member. Escape slides are packed and held within the door structure inside the slide bustle, a protruding part of the inside of an aircraft door that varies with aircraft size, door size and door location. [2] An evacuation slide is an inflatable slide that both allows people to descend safely from the exit and has a sufficiently high use rate to meet the evacuation timings. Regardless of the position of the EMER light sw in the flight deck, the F/A sw can activate the Emergency Lights. When the slide is in the armed position and the door is opened, the slide pack falls free of the door bustle (a semi-rigid outer container) and the weight and momentum of the slide pulls the lanyard from the valve, initiating the flow of gas. Due to the weight of both the door and the slide, great effort is involved in pushing the door open sufficiently to free the slide from the bustle, thus on larger aircraft a "power assist" function kicks in to aid the opening, either electrically or from compressed gas. What is so special about the outboard arm rest on each pilot seat? 3) the work that is being done, for instance whether it involves handling awkward or heavy loads, the suitability of platform or step design. On older aircraft, such as the Boeing 737, this is done physically by the cabin crew and on most other aircraft it involves pushing a lever on the door itself which arms the door internally. What is the moral lesson of at wars end by rony diaz? Training should include aircraft manufacturers requirements, awareness of emergency chute operation and deactivation and risk of falls. They should also have sufficient authority to take any necessary action if a situation of imminent danger is identified. Technical Specifications Dimensions Wing Area: 5,500 ft2 (510.95 m2) Exterior Exterior Height: 63 ft 5 in Wing Span: 195 ft 8 in Length: 231 ft 10 in Interior Cabin Width: 20 ft 0 In Internal Baggage: 6,190 cu ft Occupancy Crew: 3 Passengers: 539 Operating Weights Max T/O Weight: 735000 Lb Fuel Capacity: 48445 gal Lb Range Max Range: 5292 nm After this, some will swing to the side, whereas others retract towards or even into the aircraft's ceiling. From Boeing's data, a 747-8 cockpit ranges from 7.56 to 7.90m above the ground . Air pressure is measured in kilopascals (kPa). 51 Advice on access to aircraft can be sought from the Transportation Section in East Grinstead (503 4200) who are prepared to provide expert evidence on standards of safe access, if required. Noah's ark of the skies: Big or small, domesticated or not, Cargolux has solid expertise in transporting live animals across the world. Anchorages need to be proof tested when installed and when any usage changes. a fueling panel with two receptacles, each rated If a rapid evacuation is required and the doors are opened while "armed", the opening of the door pulls the slide pack out of the bustle (because the girt bar is physically attached to the aircraft floor). It all makes sense when you know the reasons for it! I realize the 757 is intended to be a larger aircraft, but I don't know what purpose is served by the high and low positions of each respective design. In particular aircraft structures and components are subject to stringent design requirements, and attachment points can only be provided according to manufacturer's specifications and approval. The total fuel capacity for the 787-8 is 33,528 U.S. Aircraft painted in beautiful and original liveries, Airport Overviews A detailed description of this process and the risks arising when an operative has to lean out from an unguarded high loader platform or steps can be found in SIM 05/2008/02. 25 These are part of the aircraft structure and are invariably operated by the cabin crew. [5] Prior to inflatables, some passenger aircraft utilized canvas type slides which required the crew to undertake an extensive rigging procedure. Also, most small planes are not equipped with oxygen, which would be necessary if they were to fly too high. Further guidance is also contained in various British and European standards on which the Transportation Section can advise. 11 There are 3 main types of aircraft door: 1) Passenger cabin access doors These doors are used for: Passenger access and egress Servicing the aircraft eg catering 2) Overwing (emergency. Helps a lot. Waste tank negative pressure is provided by cabin differential air when the aircraft is above ______. To sum it up, depending on the variant, a Boeing 747 aircraft is anywhere between 184 feet 9 inches (56.30 meters) and 250 feet 2 inches (76.25 meters) long. This prevents it from being released until the aircraft is on the ground, where there is not such a pressure difference. Once the bridge is positioned communication between cabin crew and ground handlers is paramount. The aircraft was on the ground at the time of the incident. Fundamentals of Engineering Economic Analysis, David Besanko, Mark Shanley, Scott Schaefer. Whereas, I think the 737 looks very short and squatty. 35,000 feet or thereabouts is the altitude at which fuel efficiency is greatest, while there is still enough oxygen available to power the engines. But there are good reasons for how high planes fly. 19 Where an air bridge is used the risk of a fall is minimised. 1 While the numbers of falls from height reported to HSE at airports has decreased significantly over recent years, there is a potential for serious injury if safe systems of work and standards are not maintained. Door status is indicated on the ECAM DOOR page. A groundbreaking concept in the air. [11], Inadvertent slide deployment occurs when the operator of the aircraft door attempts to open the door when it is in the armed position. Instead the precautions will be identified solely on the basis of an assessment of the risks involved. AIRCRAFT MODEL: WINGSPAN: . Slides fitted by main fuselage doors are mounted on the door itself. The gauge works based on air pressure, according to the formula h = 18 400 log, where h is the height above the ground in metres, P is the air pressure at height h, and P is the air pressure at ground level. The plane set to take off for Puerto Rico struck the tail of another JetBlue plane with no one inside. 35 People positioning, using and supervising the use of vehicles and other access equipment should be competent to undertake this work safely. 62 The long term aim should be better designed access equipment, better guarding, and improved design of aircraft doors and their opening mechanisms. don't know about the 757, but those 737 engines are darn low..I love the way they look though!!! An evacuation slide is an inflatable slide used to evacuate an aircraft quickly. This is partly because they tend to fly shorter distances, and pilots simply do not want to spend too much time climbing and descending on a short flight; it just isnt worth it. How do I report Air Carrier Access Act violations? Where possible the door should be closed before the steps are moved away from the aircraft. Steps or a platform must be in position outside the door before it is opened to provide protection from falling, and guard rails must be fully positioned as soon as the door is open. Slides are required on all passenger carrying aircraft where the door sill height (measured as the normal height above ground level) is such that able bodied passengers would be unable to jump or "step down" from the exit without a significant risk of injury. Thanks guys. For B767-200 the answer is from 4.14m to 4.50 (height to the door, not strictly the cockpit, for which max and min should be slightly more extreme due to distance from centre of Continue Reading 10 To be suitable the assessment should consider the issues identified above. Everything from the Goodyear blimp to the Zeppelin, Night Photos Depending on Aircraft Gross weight and strut compression, the Any reason why? 49 Documents which give general advice on working at heights are listed at Appendix 1 . Be sure to read my blog post on how to prevent damage to power wheelchairs on airplanesand also the FAQ article, 4 ways to prevent wheelchair damage in air travel. To activate the slide, one must pull the front cover to a 90 degree angle, then pull the slide out so it is lying flat on the floor or door sill, open the emergency exit and kick or push it out. Doors should never be left unprotected once open. Additionally, Flight Attendants receive extensive safety training that covers the use of evacuation slides. The distance from ground to belly is in the range of 188 to 208 cm for classical 747-s - except for 747SP, which stands taller, the landing gear of 747SP is higher and the underbelly is higher from ground than on 747 classic. This is for guidance only; any enforcement should be determined by the circumstances found on site. In the longer term we should be asking companies to come up with a programme and timetable for replacement or improvement of equipment where necessary. Inspectors are encouraged to enquire into manufacturers' and airline guidance on such things as opening aircraft doors and positioning of access equipment, and to ensure that safe access is covered as part of routine employee training programmes. There should be checks of all equipment (vehicles, platforms, guard rails, harnesses, etc.) 787-8 DOOR LOCATIONS AND DIMENSIONS As the thread title says - anyone know how high the door of a 737 is off the ground? 2) the availability and adequacy of any existing fall protection measures including guarding and personal fall protection systems. for 500 U.S. gallons per minute (1,893 liters per Aircraft ground equipment Passenger boarding bridge or transfer vehicle Requirements for interface with aircraft doors. A dramatic video shot on a smartphone from the ground shows the last moments before the plane crashed in a gorge about 1.6 kilometers (a mile) from newly opened Pokhara International Airport. 21 Whether the door is opened from inside or outside, the steps and adjustable guard rails should be positioned as close to the aircraft as possible to avoid risks of falls from the platform or the open door. Older slides are yellow and made of neoprene/nylon fabric. A farmer has 19 sheep All but 7 die How many are left? However, a planes engines need oxygen in order to function, so flying too high can also cause problems. Airliners.net is the leading community for discovering and sharing high-quality aviation photography. In the center, forward part of the pack, a multi-layered piece of heavy urethane or neoprene/nylon fabric, called the girt, is left hanging out to a length of about 2ft (0.61m). Props and jets from the good old days, Flight Decks Which color illuminates in a switch to inform the crew that a system is available? 37 Supervisors with a responsibility for ensuring that the workplace is safe must be able to recognise any inadequacies in equipment or work practices and will therefore need suitable training. What is the height from the ground to the bottom of the cargo door on a KC-135? Lastly, flying high gives you more time to act in the unlikely event of an emergency in flight. If carried out externally there may be impact from the weather conditions such as high winds. State the rationale for any abnormalities and identify any treatment needed. The assessment should recognise the potential for serious injury arising from low falls as well as high falls. 15 Aircraft doors should only be operated by door trained personnel such as trained ground staff, cabin crew, engineers or other competent workers. What is the height from the ground to the bottom of the cargo door on a KC-135? Particularly a SunCountry 737-800 ? How do wheelchair users get on airplanes? Piston engines do not operate well in thin air, and this is one of the reasons why most small planes fly at altitudes of below 15,000 feet. Typically, this will involve providing guarded access equipment and fall protection equipment. As the larger member of the A220 Family, the A220-300 is perfectly tailored for the 120-160 seat market. and will not operate, as the system is disabled by the aspirators on the slide taking in water. Offering customers one of the most spacious interiors of all single-aisle aircraft, it also delivers impressive economics. 24 The Turnround Plan should ensure that all ground staff have completed their tasks and left the aircraft or can exit safely using passenger steps before doors are closed and steps removed. Canvas type slides are still found on some out of production Russian aircraft. In such circumstances the use of personal fall protection equipment connected to a suitable anchorage point may be an acceptable solution, if there are no alternative means of protection. Slides and slide/rafts can be detached from the aircraft. For further information on the MoU, see Appendix 1 guidance and reference material. 3 Risks to ground handlers and aircraft crew have been identified during opening of the aircraft door, when the door must be cracked and then opened, sometimes swinging out from the aircraft body. There should also be a suitable procedure for the closing of the door and retraction of the air bridge. This will require specific training to be provided for each type of vehicle, equipment, guarding system or fall restraint system used. This contrasts with the Boeing 747 as doors found on that aircraft have no such system; should the slide not reach the ground, the doors must be blocked to prevent passenger injury. What is the reason for the low ride height of the 737, as I think it limits the length the fuselage can be stretched? The Fuel Quantity Display is located on the ________. Modern airliners are incredibly safe most of the time, but should something happen which means an emergency landing is required, high altitude gives the pilots much longer to sort things out and find a safe place to land. What happens if an airline damages my wheelchair? foward galley cabin circuit breaker panel. Today some of the corporate jets can fly at 51,000 feet. An airplane altimeter is a gauge that indicates the height of the plane above the ground. Passing through an aircraft door represents the start or end of one's time onboard an aircraft. The reasons behind the quirk. The 757 sits very high, making it, I think, much more imposing looking. Aircraft General DIMENSIONS Width : 35.79 m Lenght : 39.5 m . Contravention of the ANO or any Regulations made under it is a criminal offence. Where are the Live TV circuit breakers located? 30 The provision of equipment with edge protection may not be reasonably practicable for some tasks of short duration or where guard rails cannot be positioned fully, for instance when opening aircraft doors outwards. AIRCRAFT MODEL: WINGSPAN: HEIGHT: LENGTH: A300: 147 ft: 2 in: 54 ft: 6 in: 177 ft: 3 in: A300-600R & 600F: 147 ft: 1 in: 54 ft: 7 in: 177 . 12 Some aircraft doors are automated or semi-automated which can reduce the risks of approaching an unguarded edge to open or close the door. 16 Open aircraft doors must be protected by effective fall prevention barriers, ground support equipment or other means. The flight took off once all . Doors Dimensions: Main Entry Door (front right): 34 by 72 inches Both military and civil versions, Blimps / Airships [4] Today Air Cruisers is part of Zodiac Aerospace and ultimately owned by Safran who are the world's largest provider of evacuation slides. Any standard fuel truck (i.e., hydrant/tanker) NOTE: All passenger cabin doors may be used for emergency evacuation, Cargo and hold doors are not included in this guidance. Typically, aircraft fly around 35,000 or 36,000 feet above sea level. Wiki User 2010-05-04 18:35:56 Study now See answer (1) Copy Depending on Aircraft Gross weight and strut. The aircraft had a takeoff weight of 892,450 pounds (404,810 kg), and in order to satisfy Fdration Aronautique Internationale regulations, climbed to a height of 6,562 feet (2,000 m). It is the responsibility of those involved in both organisations to liaise where they believe there may be a joint interest or need for clarification of responsibilities to ensure that such matters are dealt with effectively, and to ensure there is no conflict of responsibilities with the other organisation. Many travelers have been surprised at the airport when they are told that their power wheelchair will not fit. Journalist - A graduate in German, Jake has a passion for aviation history, and enjoys sampling new carriers and aircraft even if doing so demands an unorthodox itinerary. The high pressure of the cabin forces the wedge-shaped, plug-like door into its socket. The aircraft is equipped with ____ cabin doors. The manufacturer's instruction should include a method of work for safely opening the door and positioning the steps. What are Special Service Request (SSR) codes? The entire, self-contained slide pack is approximately 3ft (0.91m) wide, 2.5ft (0.76m) long and about 1ft (0.30m) high, depending on aircraft type. When he tired of the cracking and got ready to do some eating, he discovered he had 194 total pieces (whole nuts, shell halves, and kernels). 59 Consideration should be given to risk control systems for equipment procurement, maintenance and thorough examination, as well as training in procedures, selection and use of equipment, systems for maintaining edge protection and restricting access to unguarded edges, and management control of contractors. A bit out of topic, but since the 757 and 737 have the same fuselage width, do they share any similar parts? Over 42,000 flights take place every day, with 5,000 planes in the sky at any one time, according to the FAA. To compensate for any wind, new evacuation slides contain internal baffles, which cause the ends nearest the aircraft to inflate first, which are constructed to come out like four elbows and press against the fuselage of the aircraft to the forward and aft sides of the exit door. with the appropriate length fuel line that can Anyway, I was curious about the ground height of the 757 in relation to the 737. Gravity will then pull the slide to the ground and it will inflate. But there are good reasons for how high planes fly. Federal Aviation Administration and EASA regulations require an approved method of escape on all aircraft exits where the floor is 6 feet (1.8m) or more above the ground). Ground to Fuselage Height: 14 feet 10 inches Minimum 15 feet 7 inches maximum. These are usually cylindrical, hollow aluminum tubes with sliding cylindrical or internal flapper doors that open when high pressure gas is applied, and close when the gas stream subsides and the internal slide back pressure reaches about 2.5 - 3.0 psi. Note that powered wheelchairs with a reclining seatback often require much more significant disassembly. Both military and civil versions, Blimps / Airships In many modern planes, to reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. CHENNAI/NEW DELHI/BENGALURU: An emergency exit of an Indigo flight was accidentally unlocked by a passenger last month while the aircraft was on the ground, delaying it for over two hours. One of the newest developments in evacuation slide technology can be found on the Airbus A380, which was developed by Goodrich Aircraft Interior Products. Hope this helps. minute) at 55 pounds per square inch (psi) gauge Typically there are two high pressure hoses attached to the valve, which are connected at the other end to aspirators. Movement of the _______ are a computerized response to a side stick or autopilot request. 45 The CAA Safety Regulation Group (SRG) and HSE are both involved in enforcing existing legislation and standards at airports in line with their statutory responsibilities. If the STROBE switch is in AUTO, the strobe will operate ________. Such incidents are rare, but not completely infrequent. A list of aircraft types and the dimensions of their cargo holds can be found below: Should the wheelchair require some minor disassembly to meet the size requirements of the cargo hold, airline staff are obliged to do this for you as per ACAA regulation 14 CFR 382.41 (h), provided you offer written instructions. 4) the surface on which the person is standing whilst working, including its integrity, angle, its level of slip resistance and the actual surface area available. The highest certified altitude of an airliner was Concordes 60,000 feet. Tail Height: 18.5 Metres(60 feet 9 inches) 18.5 Metres(60 feet 9 inches) 18.6 Metres(61 feet 1 inch) 18.5 Metres(60 feet 8 inch) 18.5 Metres(60 feet 8 inch) . Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes As soon as a plane lands and clears the active runway, the pilots receive taxi instructions from ground controllers. Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes This is not a factor in commercial flying. A keen amateur photographer, he also recently reached the milestone of flying his 100th sector as a passenger. Sets found in the same folder A320/321 Oxygen Carriers may require that passengers wishing to have battery powered wheelchairs transported on a flight check-in one hour prior to scheduled departure. However, it is important to note that this only tends to be the case on passenger aircraft. 58 Inspectors are reminded of the possible implications of an immediate Prohibition Notice and should consider the impact such a Notice might have on other workers around an aircraft, and on overall air traffic control and flight safety at the airport. But how exactly do they work? Turbulence is less common at high altitudes too. The 737 was originally designed to fly to airports that weren't handling jet aircraft, so there was a set of airstairs that stowed under the L1 door. Representatives of airlines, airports and ground handlers have worked with HSE in the development of this guidance. Type I Slides and Type II Slide/Rafts both function the same on land allowing descent from the door to the ground. cargo door on the left side (see fig. We thank you for your support and hope you'll join the largest aviation community on the web. How can I reduce the risk of my wheelchair being damaged? At wide doors typical on large aircraft these will be "dual lane" slides capable of carrying two parallel lines of evacuees. Once the slide is separated, the slide remains attached to the aircraft by a mooring line. Which SSR code describes my disability assistance needs? A 750-cubic-inch (12.3-litre) gas cylinder can fill a slide with about 850cuft (24m3) of air to a pressure of about 3psi (0.20atm) in about four to six seconds. We are looking for clear, consistent procedures, signals and communication which can be applied at all airports for each aircraft type, as far as this is possible. 777 airplanes. 65 Requirements of the Air Navigation Order should be taken into consideration, in relation to the requirements to avoid endangering an aircraft or compromising aircraft or flight safety. However, such doors do sometimes find themselves unintentionally open. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft Several factors contributed to the 767's doors having different operational characteristics to other aircraft. A fueling control panel Most of the time, flight attendants seamlessly operate these structures. Which display unit shows the Engine/Warning Display (E/WD)? How to request wheelchair assistance at the airport? 8) Mobile elevating work platforms - User safety guide. (379 kilopascal).

Whilst bigger than the Embraer E-Jets, Boeing feels this is an optimum size range for a small city jet which can also be used for medium-haul international services. With his mittened hands, he cracked open the shells. Advice or enforcement should be addressed to the parties best able to rectify an identified problem that is airport and/or airline and/or ground handler. Aircraft safety cards and in-flight safety demonstrations show the passengers where the nearest emergency exits are and how to use the evacuation slides. [13] On the primary entrance door, 1L, some of these aircraft have stairs that are either connected to the door or drop down. On the ground, the packs can receive compressed air from a ________, the APU, or the engines. 32 Attachment points must be of sufficient strength to support the load imposed by the weight of the worker in the event of a slip or trip and should be fitted and tested by a competent person. A list of aircraft types and the dimensions of their cargo holds can be found below: Should the wheelchair require some minor disassembly to meet the size requirements of the cargo hold, airline staff are obliged to do this for you as per ACAA regulation 14 CFR 382.41 (h), provided you offerwritten instructions. 5) the duration of the work and the location in which it is carried out. Large . Table 1: Risks of serious injury requiring immediate action, including consideration of a Prohibition Notice. When on Battery Power, which Dome light can be turned on? Steps or air bridges should be positioned outside the door before it is opened to provide some fall protection, even if guard rails cannot be fully positioned until the door is fully open. Tail and Winglet closeups with beautiful airline logos. 10 Some airlines have already introduced door nets to protect against falls from open doors. Wheelchairs that cannot fit upright in the cargo hold my be loaded and stored on their side, which is a recipe for significant damage to the wheelchair. A Type III inflatable ramp is a small platform that may be fitted to allow easy access from, for example, an over-wing wing exit door to an area of structure from where descent can be achieved either by a separate slide or by jumping, depending on the height. The following conditions are outlined by the ACAA regarding the carriage of a power wheelchair or scooter: If you arent sure how to disassemble your wheelchair, contact your local wheelchair supplier or reach out to the manufacturer. It can signify the optimism of beginning a new trip, or the excitement of having arrived somewhere new, or welcomingly familiar. Beautiful shots taken while the sun is below the horizon, Accidents This type is a rectangular opening of not less than 20 inches wide by 36 inches high with corner radii not greater than seven inches, and with a step-up inside the airplane of not more than 20 inches. Door opening procedures should be monitored and assessed and refresher training undertaken at suitable intervals, or if there are any incidents or changes to procedures. Also, new units are usually constructed of urethane materials and impregnated or coated with an aluminized coating so that the slide will survive for a short while even if fire is nearby. Probably seats or so are the only thing they share.. take a look at the cross sections, the 757 is a very different airplane from the 737. An extreme case of this sort of disaster was the US Airways aircraft which was forced to land on the Hudson river after a bird strike. The Boeing 737 is designed to fill the smaller jet airliners space over a given range of seats. Well the low ones are a lot easier to load without. When removing the battery is necessary, carriers must remove and package the battery in carrier-provided packaging, if asked to do so by the passenger. 35 to 60 minutes, depending on the fuel pressure. 40 Fall restraint equipment should be inspected and maintained according to relevant manufacturers recommendations. Cabin Height: 7 ft 4 In Cabin Width: 12 ft 2 In Cabin Length: 90 ft 2 In Cabin Volume: 6,825 cu ft Door Height: 6 ft 1 In Door Width: 2 ft 8 In Internal Baggage: 128 cu ft Occupancy Crew: 3 Passengers: 19 Operating Weights Max T/O Weight: 169785 Lb Max Landing Weight: 145505 Lb Operating Weight: 97653 Lb Empty Weight: 82078 Lb Figure 6. There are a number of reasons for all of the above, which we will take a look at now. An escape slide is required on all commercial (passenger carrying) aircraft where the door sill height is such that, in the event of an evacuation, passengers would be unable to step down from the door uninjured (Federal Aviation Administration requires slides on all aircraft doors where the floor is 6 feet (1.8m) or more above the ground). Escape slides are the reference means of compliance with the regulation although some cargo aircraft use different methods. Fuel receptacle ground height for the 787-8 and other Boeing airplanes is shown in figure 7. Our large helicopter section. While HSE is aiming for maximum protection for ground workers at airports, the airlines responsibility for cabin crew must also be considered, with consistent procedures to facilitate training. [8] Even where only a Type I slide is fitted it has sufficient buoyancy to act as an aid in the event of a water landing. Signals may include `thumbs up' or a code of knocking on the door. 44 The legal framework for the management of risks to employees and others is set out in the Health and Safety at Work etc Act 1974 and the Management of Health & Safety at Work Regulations 1999. Such nets or restraint systems must be adequately tested and secured. Clear procedures and signals should be used to open the door. The main reason for airliners flying so high is that it saves fuel and therefore saves money, which is always a priority for airlines. Once made of steel, most cylinders now are made of aluminum or alloy cores wrapped with fiberglass, or other lightweight, fuel saving materials. This costs the industry millions in lost revenue every year, estimated at $20 million in North America by cabin crew alone.[12]. Airport overviews from the air or ground, Tails and Winglets Ground Height). What are the names of the control laws that are used to operate the flight controls? Electrical anti-ice is operated for all flight operations to inhibit ice build up. This is rarely used however, because the lanyard attached to the handle runs through the girt to the valve, which is several inches too short when the girt is extended fully. Other means of access includes service vehicles such as catering high loaders. Some Russian-built aircraft like the Tupolev Tu-154 have a very complicated process to activate and deploy the slides. Prior to moving the equipment the operator should advise any personnel on board the aircraft and/or the person responsible for the operation around the aircraft that the equipment is to be removed. Memorandum of Understanding between HSE and CAA, Access steps in use without guard rails on steps or upper platform, Position existing guard rails or take steps out of use until suitable guard rails are fitted, Ground handler reaching across unguarded gap at height to open/close aircraft door without suitable guard rails or personal fall protection, Adequately guarded access equipment or personal fall protection to be provided and used, with suitable training, Aircraft doors open and unguarded when passengers or workers on board aircraft, Door to be guarded/ protected or closed, or ground support equipment to be positioned outside aircraft to provide protection, Preventing falls from height from, or when opening or closing aircraft doors. The minimum for these large jets would sit around . Where procedures exist for opening other aircraft doors for routine turnround, airlines should have contingency plans in place for any unforeseen access difficulties, airport diversions or emergencies. Have you ever witnessed an event in which an unauthorized attend has been made to open one? They work on the Venturi principle, and draw outside air into the evacuation unit at a rate of about 500:1. In 1965 the idea was further developed by combining the inflatable slide with an integrated raft. Folding or collapsible power wheelchairs that can fit into the cabins wheelchair stowage area must be stored there if the space is not already occupied by another wheelchair. If the battery on the wheelchair is labeled as non-spillable by the manufacturer, or if the wheelchair can be loaded, stored, secured and unloaded in an upright position in the cargo hold, the battery does not need to be removed from the wheelchair. 9) Preventing falls from boom-type mobile elevating work platforms HSE Information Sheet MISC 614, 10) Preventing falls from mobile elevating work platforms and selection and use of fall protection equipment OC 314/20, 12) Memorandum of Understanding between HSE and CAA, 13) BS EN 1915 Aircraft ground support equipment - general requirements Part 1: Basic safety requirements. (Typically, modern slides are made of at least two inflation chambers, and should be able to evacuate an aircraft even when one chamber loses all pressure.). Before removing GSE the Equipment operator must ensure that the door has been closed and secured by an authorised person, or that a clearly visible safety device has been placed across the opening. The failure to undertake a risk assessment should be dealt with by reference to the EMM. 26 Once an aircraft door is open and guarded steps are in position, the access may be used by authorised cleaners, security, airline employees, or passengers as necessary without risk of falls from unguarded edges. An open door displays in _____. Because of the accidental emergency slide deployment that followed, the flight ended up being delayed for seven hours. Airline personnel can assist you with this, if you bring the tools (typically a small wrench to loosen bolts) with you. Various forms of indicators, such as lights, flags and pins with ribbons are used to indicate an armed condition.[10]. 27 Where doors are used solely for servicing the aircraft, such as loading catering and galley supplies, they may be opened from inside by authorised/ trained cabin crew, in which case the same requirements apply as with passenger doors above. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft As well as being held in place by its latches, the door is effectively sealed by the pressure difference between the plane's cabin and the air outside it. Why didn't they make the 757 wider. Here are the 10 steps from arrival to take-off: 1. This should be considered as a strategic factor for the purposes of the EMM. To meet this, all evacuation units need to deploy in less than 10 seconds. 22 Once the door is open adjustable guard rails on the access steps should be extended and locked in place such that the risk of any personnel/ equipment falling through the gaps between the aircraft and access steps is minimised. [1] To reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. Type IV combines the ramp and slide into a single functional unit. 34 Employees involved in airside operations must receive specific training on airside safety awareness, vehicle and aircraft familiarisation, aircraft approach and full use of safety features and procedures, including relevant turnaround plans, whilst servicing aircraft. These include the Boeing 767, Boeing 757, and Airbus A320-series aircraft. 6). Procedures may also include a count down before opening the door. Indeed, they often fly much lower than this. The Management Regulations also set out requirements for co-operation and co-ordination between employers. Posted on August 27, 2021 - 5 minute read. Both slides and slide/rafts use non-explosive, inert gas inflation systems. The procedure to use this exit may involve removing a plug-type pressure bulkhead, or a swing type door that leads directly to a walkway. The cylinder's volume can be between 100 and 1,000 cubic inches (1.6 and 16.4 litres), pressurized to about 3,000 pounds per square inch (200 standard atmospheres) with either gaseous Nitrogen (N2), or a mixture of Carbon Dioxide (CO2) and Nitrogen. It works by sounding an audible alert (voice) when the door operator, whether trained or not, is about to open the door in the armed position. Fuel Receptacle Figure 7. Can the aircraft be flown with the Cabin Surveillance System (CSS) inoperative? [1] There are also design requirements for passengers to be able to evacuate within certain limits; typically 90 seconds for large aircraft. Taking the FWD entry door sill height as an example. Check these cargo hold dimensions! 64 The industry has worked with HSE on this issue and there is general industry acceptance that the standards outlined in this document are reasonably practicable. Accident, incident and crash related photos, Air to Air [9] Certain slides on board the aircraft have the Tribrid Inflation System, which is connected to a sensing system within the door. Aircraft painted in beautiful and original liveries, Airport Overviews Boeing airplanes is shown in figure 7. a. 43 The Lifting Operations and Lifting Equipment Regulations 1998 also apply to high loader vehicles. Views from inside the cockpit, Aircraft Cabins 20 These may be provided by the ground handler, the airport or the airline operator and should be designed to be compatible with the aircraft type, and to provide adequate protection from risk of falls. Planes flying in approximately westerly directions have to fly at even altitudes. This damage can be classified as follows: A dual lane slide is one that is capable of carrying two parallel lines of evacuees and is typically used at the main doors on Widebody aircraft. 1) The Work at Height Regulations 2005 SI 2005 No735, 2) SIM 05/2002/52 - Safe external access and working platforms at aircraft during maintenance, 3) SIM 05/2008/02 - Safe access to aircraft for catering operations, 5)OC 282/30- Inspection of fall arrest equipment made from webbing or rope, 6) OC 234/11 - Lifting Operations and Lifting Equipment Regulations 1998, 7) INDG 367 Inspection of fall arrest equipment made of webbing or rope. receptacle ground height for the 787-8 and other Can I check my wheelchair at the boarding gate? For large, wide body aircraft such as A380s and B747s a successful deployment is complete in about five to seven seconds, depending on conditions (such as temperature and winds). All new evacuation slides are tested on a mock-up of an aircraft exit door and filmed prior to being certified as airworthy and delivered to a customer. 41 Every employer has a duty to protect so far as is reasonably practicable the health and safety of their employees whilst working at a height. 56 Table 1 sets out some risks of serious personal injury that require immediate action, after which further action may be necessary to secure compliance and to achieve the benchmark of negligible risk of serious personal injury. An escape slide is required on all commercial (passenger carrying) aircraft where the door sill height is such that, in the event of an evacuation, passengers would be unable to step down from the door uninjured ( Federal Aviation Administration requires slides on all aircraft doors where the floor is 6 feet (1.8 m) or more above the ground).

Our site uses cookies. As far as possible signals and procedures should be standardised to avoid confusion for cabin or ground crew. It should be noted that every airplane has a certified maximum altitude. Airport overviews from the air or ground, Tails and Winglets With this much traffic, there has to be some official arrangement to make sure collisions do not happen, and there is. Passenger The slides are stored in cabinets usually beside the emergency exit inside the aircraft. This is why when you are cruising in an airliner, it is usually bright and sunny, with all the cloud and rain below you. According to Quora user and aircraft maintenance engineer Jan Krusat, the makeup of the 767's design team played a key role. Modern planes often indicate an armed condition with an indicator light. 38 Where a company has specialist equipment, including equipment designed and constructed for use with only one type of aircraft or limited types, staff should be sufficiently competent to recognise and select the right equipment for the aircraft and task at hand. However, legally planes must be at least 1000 feet above any object on the ground, and must be able to land clear of any congested area in the event of an engine failure. Prior to departure (usually before engine startup), all the aircraft doors are placed into the armed (or automatic) mode by the cabin crew. Stay informed:Sign up for ourdailyandweeklyaviation news digests! What does this mean emulate what you respect in your friends? Data not published, based on our estimates, center aisle. The . Commercial airplanes can theoretically fly a little higher than this, and of course they can also fly lower if they choose to. One end has a buckle to connect to attachments on the aircraft's wings. It can be installed as a stand-alone unit or integrated into the aircraft systems and powered from aircraft power. These restraints are constructed so that when the slide becomes fairly rigid, at around 1.5 to 2psi (0.10 to 0.14atm), they detach very quickly (there are usually two), and since the header tubes are already against the fuselage, the slide pops almost horizontally out from the door, then drops relatively gently to the ground. To avoid rapid depressurization, it is paramount that these structures cannot be breached inflight. Methods of arming vary from aircraft to aircraft, but ultimately the girt bar (a metal bar attached to the door end of the slide) is physically attached to brackets either in or adjacent to the door sill. Wing Anti-ice is operated in flight when required by icing conditions, but can also be operated for ______ on the ground for testing purposes. Which of the External Lights will automatically turn off when the landing gear is retracted, regardless of the position of their control switch? 63 A failure by inspectors to take enforcement action where the EMM and local factors indicate such action to be appropriate may have a negative impact upon employers' attitudes.
