If carried out externally there may be impact from the weather conditions such as high winds. 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. (4) Type IV. Aircraft doors are designed to be used on the ground, where they are not subjected to the pressure difference found at altitude. Aircraft safety cards and in-flight safety demonstrations show the passengers where the nearest emergency exits are and how to use the evacuation slides. 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. Everything from the Goodyear blimp to the Zeppelin, Night Photos 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. Carriers may require that passengers wishing to have battery powered wheelchairs transported on a flight check-in one hour prior to scheduled departure. I'm surprised to see the door height of the 732 even lower than that of the 733/4! 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. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft 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. 3) the work that is being done, for instance whether it involves handling awkward or heavy loads, the suitability of platform or step design. Specifically, several members of this group were former McDonnell Douglas engineers. Plus if a plane goes higher, it has to burn more fuel in order to get there. TRUE/ FALSE. reserve, the 787-8 can be refueled to capacity in In addition, jet engines operate more efficiently at high altitudes, meaning the plane can travel faster while at the same time burning less fuel. Therefore small planes generally fly between 2000 and 10,000 feet. What are the TSA security procedures for wheelchair users? All a snowbound skier had to cat were walnuts! It can be installed as a stand-alone unit or integrated into the aircraft systems and powered from aircraft power. Such nets or restraint systems must be adequately tested and secured. 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. 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. Typically, aircraft fly around 35,000 or 36,000 feet above sea level. Can the aircraft be flown with the Cabin Surveillance System (CSS) inoperative? 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. Latch-on guarantees fore and aft and vertical alignment of the loader bed with the aircraft doorway, when used in . Pictures of great freighter aircraft, Government Aircraft 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. However, such doors do sometimes find themselves unintentionally open. In fact, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet, or between about six and nearly eight miles above sea level. height: 13'2 - 4.01 mtr Below the link to the Boeing manual: http://www.boeing.com/assets/pdf/commercial/airports/acaps/757_23.pdf Regards, Marcel van Noordenne Reply AZguy says: November 14, 2017 at 09:02 does not give the interior width Reply Everything from the Goodyear blimp to the Zeppelin, Night Photos Airliners.net is the leading community for discovering and sharing high-quality aviation photography. State the rationale for any abnormalities and identify any treatment needed. What can we see in terms of the general dimensions of Y1, in this respect? Communication is again paramount. Electrical anti-ice is operated for all flight operations to inhibit ice build up. This is why when you are on a long flight, you will . Previously life rafts were carried separately in the cabin and deployed manually by the crew after a water landing. Aircraft flying government officials, Helicopters 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. 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. 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. 10 Some airlines have already introduced door nets to protect against falls from open doors. 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. Passing through an aircraft door represents the start or end of one's time onboard an aircraft. Seeing a gap in the market for a regional aircraft with mainline capabilities, we launched the E190. What is the height from the ground to the bottom of the cargo door on a KC-135? As soon as a plane lands and clears the active runway, the pilots receive taxi instructions from ground controllers. Approximately how high is the bottom of the cabin door from the ground? If the exit is located over the wing, the step-down outside the airplane may not exceed 27 inches. A bit out of topic, but since the 757 and 737 have the same fuselage width, do they share any similar parts? 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. AIRCRAFT MODEL: WINGSPAN: . 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). 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. Type IV combines the ramp and slide into a single functional unit. 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. Have you ever witnessed an event in which an unauthorized attend has been made to open one? In many modern planes, to reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. . 787-8 DOOR LOCATIONS AND DIMENSIONS 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. For the slide to deploy correctly, it is packed in a manner that has the aspirators directly under the outer cover. 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. 40 Fall restraint equipment should be inspected and maintained according to relevant manufacturers recommendations. To meet this, all evacuation units need to deploy in less than 10 seconds. Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes As the larger member of the A220 Family, the A220-300 is perfectly tailored for the 120-160 seat market. The 757 sits very high, making it, I think, much more imposing looking. 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. Which display unit shows the Engine/Warning Display (E/WD)? One of the newest developments in evacuation slide technology can be found on the Airbus A380, which was developed by Goodrich Aircraft Interior Products. NOTE: All passenger cabin doors may be used for emergency evacuation, Cargo and hold doors are not included in this guidance. Sometimes, this seems to happen by itself, as was reportedly the case with a Pakistan International Airlines ATR 42 while landing in Sukkur last year. Lower aircraft usually do not require such means of access, and have not been taken into account. The regulating valve mechanically meters out the gas at a pressure of roughly 300 to 600 pounds per square inch (20 to 41atm) and a rate of about 4 cubic feet (0.11m3) per minute. The Fuel Quantity Display is located on the ________. Aircraft ground equipment Passenger boarding bridge or transfer vehicle Requirements for interface with aircraft doors. Note that powered wheelchairs with a reclining seatback often require much more significant disassembly. When the door is placed in the armed position, the device is armed. Airport overviews from the air or ground, Tails and Winglets What is the condition of the Slide Arming Lever when the yellow arm plate is down and flush with the door? and will not operate, as the system is disabled by the aspirators on the slide taking in water. Turbulence is less common at high altitudes too. 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. 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. Heads up this was for Grand Forks Flight Support who will be handeling a SunCountry 737-800 charter for UND Fighting sioux football tomorrow. This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. Where attachment points are on guard rails, the rails must be of sufficient strength to withstand foreseeable forces. Short hops or longer routes - the E190 has the versatility to go the distance. The 787-8 is equipped with eight passenger entry 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. Anyway, I was curious about the ground height of the 757 in relation to the 737. two cargo doors on the right side, and one bulk 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. These types of aircraft have a door sill height greater than 2,0 m (80 in) above the ground. The aircraft is equipped with ____ cabin doors. Batteries that appear to be damaged or leaking may be removed and separately packaged by the carrier. These include serious risks of injury if the emergency chute is accidentally activated, and falling from an unguarded door if there is no ground support equipment in place. They rarely ask about it, or want to know what altitude is used. This sort of thing is extremely unlikely, but it does happen occasionally. What rights do airline passengers with disabilities have in Europe? Where immediate prohibition could cause significant health and safety or air safety risks, a deferred notice should be considered. Figure 7. This costs the industry millions in lost revenue every year, estimated at $20 million in North America by cabin crew alone.[12]. More specifically, they are smaller than 25 inches. On the other hand, flying too high could have negative safety issues. It all makes sense when you know the reasons for it! 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. Window exits usually come in two configurations: Window exits are usually equipped with ditching or life lines. 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. (Continue to next page) 14 Signals in use for door opening procedures vary at UK airports and between aircraft operators. These may be attached to the inside frame of the window exit, or located in a nearby storage locker. A fueling control panel HSE aims to reduce work-related death, injury and ill health. 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. 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. 6) there are damage or defects to access equipment or fall protection equipment which give rise to significant risks an Improvement Notice should be considered. To avoid rapid depressurization, it is paramount that these structures cannot be breached inflight. Large . 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. Both slides and slide/rafts use non-explosive, inert gas inflation systems. 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. While jet engines operate well at high altitudes, the same is not true of piston engines, which are typically used for light aircraft of the type flown by most private pilots. Interpret F.N. [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. But there are good reasons for how high planes fly. Canvas type slides are still found on some out of production Russian aircraft. Where possible the door should be closed before the steps are moved away from the aircraft. Typically, this will involve providing guarded access equipment and fall protection equipment. 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. The air becomes thinner as the altitude increases, and thin air creates less drag on the aircraft. Noah's ark of the skies: Big or small, domesticated or not, Cargolux has solid expertise in transporting live animals across the world. When installed in the aircraft, a girt bar is put through the center, outside end of the girt and attached to the interior floor, just inside and in front of the exit door. FUEL RECEPTACLE GROUND HEIGHT Ground Height). 39 Doors should only be opened by door trained personnel. Our site uses cookies. 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 stairs and bridges are common with 767 and [13] On the primary entrance door, 1L, some of these aircraft have stairs that are either connected to the door or drop down. [9] Certain slides on board the aircraft have the Tribrid Inflation System, which is connected to a sensing system within the door. 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. What is so special about the outboard arm rest on each pilot seat? 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. Your reliance on this aircraft size information is at your own risk. 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. We have established the mechanical means by which aircraft doors are kept shut, but there is another aspect to consider.
