Commercial airplanes usually fly above the troposphere, which is the part of the atmosphere where weather events usually happen. Engine anti-ice is supplied to the _______. Anyway, I was curious about the ground height of the 757 in relation to the 737. 39 Doors should only be opened by door trained personnel. 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. A bit out of topic, but since the 757 and 737 have the same fuselage width, do they share any similar parts? This costs the industry millions in lost revenue every year, estimated at $20 million in North America by cabin crew alone.[12]. Cargo Door (LH) Clear Opening Width: 134 in (3.4 m) Height: 103 in (2.6 m) Forward Lower Deck Cargo Door Clear Door Opening Width: 134 in (above rollers)(3.4 m) Height: 69 in (1.7 m) Aft Lower Deck Cargo Door Clear Door Opening Width: 70 in (above rollers)(1.7 m) Height: 69 in (1.7 m) (24) 88 in x 125 in x 96 in Longitudinal Pallets/Containers . 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. Flying higher means that commercial airplanes can avoid most other airborne traffic. Cargo holds vary in size, based on the aircraft type. Slides and slide/rafts can be detached from the aircraft. Typically, this will involve providing guarded access equipment and fall protection equipment. This is all in addition to any maintenance that is specified by the manufacturer. Plus if a plane goes higher, it has to burn more fuel in order to get there. In such cases, safety equipment must be used and certain precautions followed. Electrical anti-ice is operated for all flight operations to inhibit ice build up. Seeing a gap in the market for a regional aircraft with mainline capabilities, we launched the E190. [13] On the primary entrance door, 1L, some of these aircraft have stairs that are either connected to the door or drop down. What are the names of the control laws that are used to operate the flight controls? Lastly, flying high gives you more time to act in the unlikely event of an emergency in flight. The aircraft was on the ground at the time of the incident. How do I report Air Carrier Access Act violations? 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. Passing through an aircraft door represents the start or end of one's time onboard an aircraft. Carriers may require that passengers wishing to have battery powered wheelchairs transported on a flight check-in one hour prior to scheduled departure. 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 . 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? It represents the fusion of performance and technology, allowing airlines to connect distant points on continents and for route sectors that were previously unprofitable or impossible to perform. This damage can be classified as follows: 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. This may mean modifying the equipment or using fall restraint equipment in the short term. 19 Where an air bridge is used the risk of a fall is minimised. Lower aircraft usually do not require such means of access, and have not been taken into account. Waste tank negative pressure is provided by cabin differential air when the aircraft is above ______. 14) BS EN 12312 Aircraft ground support equipment - specific requirements: Part 8: maintenance stairs and platforms - due for publication. 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. 777 airplanes. 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. The Management Regulations also set out requirements for co-operation and co-ordination between employers. 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. Large . Your reliance on this aircraft size information is at your own risk. 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. . All a snowbound skier had to cat were walnuts! Parking the plane. This line will break if the airframe submerges, or can be disconnected with a pre-supplied knife or disconnect handle. However, not all of these documents or standards are specific to aircraft access and will need to be interpreted in the light of the task and the law, as summarised earlier. How many video display units are installed in the cockpit? The practice of differentiating between the precautions required for high falls and low falls will no longer apply. 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). Any standard fuel truck (i.e., hydrant/tanker) 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. Delta Air Lines' departing Boeing 737 plane then came to a safe stop on the John F. Kennedy International Airport runway as the other crossed in front around 8:45 p.m., the Federal Aviation . [11], Inadvertent slide deployment occurs when the operator of the aircraft door attempts to open the door when it is in the armed position. Some switches illuminate a ____ light when they are selected ON, to advise the crew that they are selected on and operating. If the door is opened in emergency mode at an abnormal attitude (e.g. Therefore small planes generally fly between 2000 and 10,000 feet. Stay informed:Sign up for ourdailyandweeklyaviation news digests! 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. Thanks for any help or direction where i can find this answer. Batteries that appear to be damaged or leaking may be removed and separately packaged by the carrier. Boeing 747 Tail Height. The aircraft is equipped with ____ cabin doors. Every type from fighters to helicopters from air forces around the globe, Classic Airliners These include the Boeing 767, Boeing 757, and Airbus A320-series aircraft. 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. Figure 6. They should also have sufficient authority to take any necessary action if a situation of imminent danger is identified. What are the TSA security procedures for wheelchair users? How can I reduce the risk of my wheelchair being damaged? Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft In some emergencies, such as a rapid decompression, pilots want to return to a lower altitude as quickly as possibe. 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. 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. **Laboratory Testing**\ Wing Anti-ice is operated in flight when required by icing conditions, but can also be operated for _____ on the ground for testing purposes. TRUE/FALSE. So again, there has to be a balance, which accounts for the altitudes generally used. 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. The inflation system usually consists of a pressurized cylinder, a regulating valve, two high pressure hoses and two aspirators. Aircraft doors refer to passenger doors, cargo doors and ground service access doors to various areas of the fuselage. If the exit is located over the wing, the step-down outside the airplane may not exceed 27 inches. If the STROBE switch is in AUTO, the strobe will operate ________. 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. Flight 1603 went back to the gate and was taken out of service. One of the newest developments in evacuation slide technology can be found on the Airbus A380, which was developed by Goodrich Aircraft Interior Products. At the end of the walkway is the slide pack and a manual tailcone jettison handle for use if the tailcone has not already been automatically jettisoned by opening the walkway entrance. The first aircraft evacuation slide was developed and produced by Air Cruisers, founded by James F. Boyle, inventor of the World War II life vest, the "Mae West". 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). It also made inspection and work on the engines very easy. Procedures may also include a count down before opening the door. 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. There should also be a suitable procedure for the closing of the door and retraction of the air bridge. 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. Indeed, they often fly much lower than this. Props and jets from the good old days, Flight Decks Additionally, Flight Attendants receive extensive safety training that covers the use of evacuation slides. 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. 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. But small aircraft such as those flown by private pilots cannot fly this high, and usually do not go above 10,000 feet. Props and jets from the good old days, Flight Decks 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. All cabin door are equipped with a ______. Ground Height). This incident occurred due to a passenger on the 777 mistaking the door for a bathroom while on the ground in Manchester. This is why when you are on a long flight, you will . A fueling control panel 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. AIRCRAFT MODEL: WINGSPAN: . Emerald Airlines has taken over Aer Lingus' regional routes previously operated by Stobart Air. Depending on Aircraft Gross weight and strut compression, the What is the normal configuration for switches and lights on the A320? 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. 36 Users should be instructed in the use and limitations of access equipment, and the limits on their authority to modify it. Aircraft safety cards and in-flight safety demonstrations show the passengers where the nearest emergency exits are and how to use the evacuation slides. Where immediate prohibition could cause significant health and safety or air safety risks, a deferred notice should be considered. An open door displays in _____. 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 CV precious Versed in the art of air cargo, Cargolux is your privileged airfreight partner to ship artwork and high precision machinery across the globe. 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. receptacle ground height for the 787-8 and other Aircraft flying government officials, Helicopters Signals must be clearly understood by all parties and there should be positive confirmation by a pre-agreed signal that the bridge is fully in position and the door can be opened. Wiki User 2010-05-04 18:35:56 Study now See answer (1) Copy Depending on Aircraft Gross weight and strut. 2 Risks arise during maintenance of aircraft and during servicing and turnaround activities. Some Russian-built aircraft like the Tupolev Tu-154 have a very complicated process to activate and deploy the slides. 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. 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). Minimum theoretical pavement width for a 180 turn? 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. Powered wheelchairs andscooters almost always have to be stored underneath the airplane in the cargo hold. 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. Table 1: Risks of serious injury requiring immediate action, including consideration of a Prohibition Notice. 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. They are usually about the same width and height as a seat. Gravity will then pull the slide to the ground and it will inflate. When activated, how long should the Emergency Lights last? Contravention of the ANO or any Regulations made under it is a criminal offence. Window exits usually come in two configurations: Window exits are usually equipped with ditching or life lines. They work on the Venturi principle, and draw outside air into the evacuation unit at a rate of about 500:1. 48 Specific guidance on the roles and responsibilities of those involved in aircraft turnround is given in Aircraft Turnround HSG209. Their suggestions involved planning, exiting the aircraft and getting off the slide quickly, jumping, the correct body position and avoidance of clothing that could cause safety issues, such as spiked heels and pantyhose. A keen amateur photographer, he also recently reached the milestone of flying his 100th sector as a passenger. 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 main reason for airliners flying so high is that it saves fuel and therefore saves money, which is always a priority for airlines.
