Slides fitted by main fuselage doors are mounted on the door itself. From Boeing's data, a 747-8 cockpit ranges from 7.56 to 7.90m above the ground . Some switches illuminate a ____ light when they are selected ON, to advise the crew that they are selected on and operating. On February 9, 2020, a British Airways Boeing 747-400 broke the New York-London subsonic airliner speed record in 4 hours 56 minutes, pushed by the . The highest certified altitude of an airliner was Concordes 60,000 feet. 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 . Plus if a plane goes higher, it has to burn more fuel in order to get there. So again, there has to be a balance, which accounts for the altitudes generally used. Beautiful shots taken while the sun is below the horizon, Accidents A fueling control panel 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. 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. Ground Height). 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. Thanks for any help or direction where i can find this answer If you look on page 45 of this document, the table states the height of the Fwd passenger Entry Door in 9ft off the ground and the Aft Passenger Entry Door is 10ft 3in off the ground for the 737-800. In such cases, safety equipment must be used and certain precautions followed. 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. 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. Another unique type of evacuation slide is found on the DC-9 family of aircraft and its successors the MD-80 and Boeing 717. There are a number of Annexes to the MoU on specific areas. This prevents it from being released until the aircraft is on the ground, where there is not such a pressure difference. A keen amateur photographer, he also recently reached the milestone of flying his 100th sector as a passenger. What are Special Service Request (SSR) codes? The failure to undertake a risk assessment should be dealt with by reference to the EMM. What is the condition of the Slide Arming Lever when the yellow arm plate is down and flush with the door? Once the slide is completely free it will fall under gravity and after travelling a certain distance a pin will be pulled from a squib containing compressed gas and the slide will inflate. Lower aircraft usually do not require such means of access, and have not been taken into account. Copyright 2023 Pilot Institute. Movement of the _______ are a computerized response to a side stick or autopilot request. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft Data not published, based on our estimates, center aisle. The LDG LT memo displays on the ECAM when ______. How to request wheelchair assistance at the airport? Powered wheelchairs andscooters almost always have to be stored underneath the airplane in the cargo hold. Specific requirements for different types of GSE are in BS EN 12312 (see Appendix 1 ). book answer is 10 feet. Have you ever witnessed an event in which an unauthorized attend has been made to open one? The 777F accommodates 27 standard pallets (96 by 125 inches; 2.5 by 3.1 meters) on the main deck. 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. This protects the chamber from catastrophic failure due to over pressurizing. 29 These doors should only be used for emergency evacuation. This costs the industry millions in lost revenue every year, estimated at $20 million in North America by cabin crew alone.[12]. 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. 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. A groundbreaking concept in the air. Signals may include `thumbs up' or a code of knocking on the door. 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). Once the bridge is positioned communication between cabin crew and ground handlers is paramount. Steps should only be removed by ground handlers on positive instruction from authorised persons eg trained cabin crew or handling staff, according to the Turnround plan. 16 Open aircraft doors must be protected by effective fall prevention barriers, ground support equipment or other means. As the thread title says - anyone know how high the door of a 737 is off the ground? Clear procedures and signals should be used to open the door. This will require specific training to be provided for each type of vehicle, equipment, guarding system or fall restraint system used. State the rationale for any abnormalities and identify any treatment needed. Cabin Door Safety Strap Cargo holds vary in size, based on the aircraft type. Large . On the ground, the packs can receive compressed air from a ________, the APU, or the engines. 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. With this much traffic, there has to be some official arrangement to make sure collisions do not happen, and there is. 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. 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). Ground to underbelly is 226 to 246 cm on SP. Should this system fail, the slide can be manually inflated by the cabin crew by pulling a manual inflation handle at the top of the slide. There should be checks of all equipment (vehicles, platforms, guard rails, harnesses, etc.) What is the reason for the low ride height of the 737, as I think it limits the length the fuselage can be stretched? Aircraft doors refer to passenger doors, cargo doors and ground service access doors to various areas of the fuselage. The total fuel capacity for the 787-8 is 33,528 U.S. Did you know how aircraft doors worked? A centrifugal pump has the following dimensions: d2 = 42 cm, L = 5 cm, and $\beta 2=33^{\circ}$. Which color illuminates in a switch to inform the crew that a system is available? 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. 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. 2) the availability and adequacy of any existing fall protection measures including guarding and personal fall protection systems. How do I report Air Carrier Access Act violations? Further guidance is also contained in various British and European standards on which the Transportation Section can advise. 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. Some Russian-built aircraft like the Tupolev Tu-154 have a very complicated process to activate and deploy the slides. But how exactly do they work? [1] To reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. receptacle ground height for the 787-8 and other It also minimizes the risk of accidental opening. 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. 777 airplanes. Chloride 103 mEq/L \ On an aircraft without a Live TV Master Power Switch, how many circuit breakers should be pulled in the event of a fire? 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. All a snowbound skier had to cat were walnuts! Other means of access includes service vehicles such as catering high loaders. During transit or during maintenance visits, the aircraft doors may need to remain open for a number of reasons. 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. The outboard armrest of each pilot seat is enlarged and has enhanced position controls to enable specific positioning of the armrest for uuse of the Side Stick. After this, some will swing to the side, whereas others retract towards or even into the aircraft's ceiling. This sort of thing is extremely unlikely, but it does happen occasionally. 49 Documents which give general advice on working at heights are listed at Appendix 1 . The door is first cracked open then the stairs positioned. AASI JETCRUZER. Glucose 202 mg/dL \ The high pressure of the cabin forces the wedge-shaped, plug-like door into its socket. Airline personnel can assist you with this, if you bring the tools (typically a small wrench to loosen bolts) with you. Airport overviews from the air or ground, Tails and Winglets 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. Tail and Winglet closeups with beautiful airline logos. Latch-on guarantees fore and aft and vertical alignment of the loader bed with the aircraft doorway, when used in . Each nut that was opened resulted in one kernel and two shell halves. 787-8 DOOR LOCATIONS AND DIMENSIONS Tests in 25-knot (46km/h) cross winds have shown these deployment systems to be very effective. 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 practice of differentiating between the precautions required for high falls and low falls will no longer apply. reach the 787-8 receptacles can be used. Aircraft safety cards and in-flight safety demonstrations show the passengers where the nearest emergency exits are and how to use the evacuation slides. 3 of 4 main doors are closed - either engine is running - ground/air logic sense airborne or both thrust levers above 53% OXYGEN Flight Crew oxygen : One oxygen bottle in the aft E&E bay, must be pressurized 1100psi for the first flight 1000psi thereafter. The aircraft is equipped with ____ cabin doors. [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. I'm surprised to see the door height of the 732 even lower than that of the 733/4! The flight took off once all . The main reason for airliners flying so high is that it saves fuel and therefore saves money, which is always a priority for airlines. [3] The patent for the inflatable escape chute assembly was submitted by Boyle in 1954 and the designs was patented in 1956 under patent number 2,765,131. And a substantial majority of small planes are flown for recreational purposes, and pilots enjoy flying lower, where they can see things below them. Assuming a 3,730-U.S. gallon (14,120-liter) Accident, incident and crash related photos, Air to Air FUEL RECEPTACLE GROUND HEIGHT Figure 7 Assuming a 3,730-U.S. gallon (14,120-liter) reserve, the 787-8 can be refueled to capacity in 35 to 60 minutes, depending on the fuel pressure. Figure 7. It should be noted that every airplane has a certified maximum altitude. 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. 15 Aircraft doors should only be operated by door trained personnel such as trained ground staff, cabin crew, engineers or other competent workers. 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. 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. 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.
