But there are good reasons for how high planes fly. Aircraft flying government officials, Helicopters Views from inside the cockpit, Aircraft Cabins 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. Transportation Section can give further advice, if required. I did a search, but returned nothing. Batteries that appear to be damaged or leaking may be removed and separately packaged by the carrier. Escape slides are the reference means of compliance with the regulation although some cargo aircraft use different methods. Ground to Fuselage Height: 14 feet 10 inches Minimum 15 feet 7 inches maximum. 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. They rarely ask about it, or want to know what altitude is used. 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. An article in Time by Amanda Ripley, with the assistance of aviation safety expert Dan Johnson, compiled some tips on how to avoid injury and escape from a plane on an inflatable slide. Boeing airplanes is shown in figure 7. 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. (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.). 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. 11 There are 3 main types of aircraft door: 3) Upper deck doors (emergency evacuation). 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. 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. Offering customers one of the most spacious interiors of all single-aisle aircraft, it also delivers impressive economics. This costs the industry millions in lost revenue every year, estimated at $20 million in North America by cabin crew alone.[12]. This damage can be classified as follows: Type IV combines the ramp and slide into a single functional unit. 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. Typically there are two high pressure hoses attached to the valve, which are connected at the other end to aspirators. Many travelers have been surprised at the airport when they are told that their power wheelchair will not fit. 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. However, such doors do sometimes find themselves unintentionally open. 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. Depending on Aircraft Gross weight and strut compression, the He was carrying a bag holding 12 dozen nuts. To be suitable the assessment should consider the issues identified above. Use of the aircraft attachment points may be used as a means of averting damage to the aircraft door frames and other important parts. TRUE/FALSE. With this much traffic, there has to be some official arrangement to make sure collisions do not happen, and there is. 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). How do I report Air Carrier Access Act violations? 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. The air becomes thinner as the altitude increases, and thin air creates less drag on the aircraft. 50 Advice on enforcement is given in paragraphs 56 - 63 describing a number of scenarios that inspectors may encounter, to aid the inspector when they are considering enforcement. 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. During transit or during maintenance visits, the aircraft doors may need to remain open for a number of reasons. 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). Several factors contributed to the 767's doors having different operational characteristics to other aircraft. If the STROBE switch is in AUTO, the strobe will operate ________. Sodium 138 mEq/L \ In some emergencies, such as a rapid decompression, pilots want to return to a lower altitude as quickly as possibe. 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. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft Tail and Winglet closeups with beautiful airline logos. 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. Because of the accidental emergency slide deployment that followed, the flight ended up being delayed for seven hours. It also minimizes the risk of accidental opening. [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. 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. This protects the chamber from catastrophic failure due to over pressurizing. 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. 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. Table 1: Risks of serious injury requiring immediate action, including consideration of a Prohibition Notice. 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? according to Boeing manual, the front passenger door: min. Our site uses cookies. 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). 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. 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. Other means of access includes service vehicles such as catering high loaders. The inflation system usually consists of a pressurized cylinder, a regulating valve, two high pressure hoses and two aspirators. 36 Users should be instructed in the use and limitations of access equipment, and the limits on their authority to modify it. 9 Airlines have the ultimate responsibility for procedures for opening their aircraft doors. by users, inspections by competent persons, as well as any statutory inspections required by Lifting Operations and Lifting Equipment Regulations (LOLER). Clear procedures and signals should be used to open the door. stairs and bridges are common with 767 and 25 These are part of the aircraft structure and are invariably operated by the cabin crew. 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. What is the condition of the Slide Arming Lever when the yellow arm plate is down and flush with the door? 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. 47 Standards for ground support equipment (GSE) are given in BS EN 1915-1:2001 Aircraft ground support equipment - General requirements - Part 1: basic safety requirements. Seeing a gap in the market for a regional aircraft with mainline capabilities, we launched the E190. 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. 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. 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. Air pressure is measured in kilopascals (kPa). 10 Some airlines have already introduced door nets to protect against falls from open doors. 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. The troposphere is usually said to finish at 36,000 feet. 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. 35 to 60 minutes, depending on the fuel pressure. 40 Fall restraint equipment should be inspected and maintained according to relevant manufacturers recommendations. 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. Accident, incident and crash related photos, Air to Air 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. 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 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. 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. (4) Type IV. But how exactly do they work? There are a number of Annexes to the MoU on specific areas. Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes 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. Assuming radial entry flow, determine the theoretical values for (a) the flow rate and (b) the power. 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. 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. 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). Views from inside the cockpit, Aircraft Cabins Figure 6. Which of the External Lights will automatically turn off when the landing gear is retracted, regardless of the position of their control switch? 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. More specifically, they are smaller than 25 inches. Older slides are yellow and made of neoprene/nylon fabric. Where immediate prohibition could cause significant health and safety or air safety risks, a deferred notice should be considered. The over-wing exits on the Airbus A320 series, Airbus A380, Boeing 747, Boeing 757, Boeing 767 and Boeing 777 aircraft use ramp slides in various configurations. Glucose 202 mg/dL \ 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. We thank you for your support and hope you'll join the largest aviation community on the web. It can signify the optimism of beginning a new trip, or the excitement of having arrived somewhere new, or welcomingly familiar. According to Ask The Pilot, aircraft doors are held in place physically by "a series of electrical and/or mechanical latches."
