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. What is the height from the ground to the bottom of the cargo door on a KC-135? However, it is important to note that this only tends to be the case on passenger aircraft. Both military and civil versions, Blimps / Airships The . 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 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. Aircraft doors are designed to be used on the ground, where they are not subjected to the pressure difference found at altitude. 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. It is not essential for aircraft to avoid bad weather, but it is a good idea. [4] Today Air Cruisers is part of Zodiac Aerospace and ultimately owned by Safran who are the world's largest provider of evacuation slides. 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. Carriers may require that passengers wishing to have battery powered wheelchairs transported on a flight check-in one hour prior to scheduled departure. a fueling panel with two receptacles, each rated The aircraft door must NOT be left unguarded during this operation. book answer is 10 feet. Based in Norwich, UK. Specific requirements for different types of GSE are in BS EN 12312 (see Appendix 1 ). On the face of the girt are instructions in large red lettering, and a handle with the word 'PULL' on it. 1) apply the standards detailed in this SIM when inspecting or discussing opening aircraft doors; 2) alert the Transportation Section to any problems which arise from applying these standards, or any of the other advice contained in this SIM; 3) draw to the attention of the Section any new or innovative means of gaining safe access or fall protection; 4) advise CAA of any matters of concern relating to the safety of aircraft uncovered during inspections or investigations; 5) inform the Transportation Section when contacting CAA to raise an issue of concern. Stay informed:Sign up for ourdailyandweeklyaviation news digests! What are Special Service Request (SSR) codes? 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). 16 Open aircraft doors must be protected by effective fall prevention barriers, ground support equipment or other means. Posted on August 27, 2021 - 5 minute read. 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. The air becomes thinner as the altitude increases, and thin air creates less drag on the aircraft. Once made of steel, most cylinders now are made of aluminum or alloy cores wrapped with fiberglass, or other lightweight, fuel saving materials. Every type from fighters to helicopters from air forces around the globe, Classic Airliners [1] To reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. 2) the availability and adequacy of any existing fall protection measures including guarding and personal fall protection systems. What rights do airline passengers with disabilities have in Europe? 33 Detailed consideration of the use of fall arrest or fall restraint equipment when opening aircraft doors from a high loader platform can be found in SIM 05/2008/02. 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. I know they had smaller engines, but surely that fuselage must've been really close to the ground?. This is why when you are cruising in an airliner, it is usually bright and sunny, with all the cloud and rain below you. Which SSR code describes my disability assistance needs? Prior to departure (usually before engine startup), all the aircraft doors are placed into the armed (or automatic) mode by the cabin crew. As the thread title says - anyone know how high the door of a 737 is off the ground? 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. We thank you for your support and hope you'll join the largest aviation community on the web. Tail and Winglet closeups with beautiful airline logos. In addition, jet engines operate more efficiently at high altitudes, meaning the plane can travel faster while at the same time burning less fuel. If it is not possible to open the door with such a platform in place, further precautions as detailed in the guidance must be utilised. Contravention of the ANO or any Regulations made under it is a criminal offence. Why didn't they make the 757 wider. 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 incident occurred due to a passenger on the 777 mistaking the door for a bathroom while on the ground in Manchester. One end has a buckle to connect to attachments on the aircraft's wings. With his mittened hands, he cracked open the shells. Thankfully, the nature of physics renders this task impossible. Where attachment points are on guard rails, the rails must be of sufficient strength to withstand foreseeable forces. Airline personnel can assist you with this, if you bring the tools (typically a small wrench to loosen bolts) with you. Clear procedures and signals should be used to open the door. The LDG LT memo displays on the ECAM when ______. Some Russian-built aircraft like the Tupolev Tu-154 have a very complicated process to activate and deploy the slides. 8) Mobile elevating work platforms - User safety guide. 60 Given the potential for injury it is essential that a suitable and sufficient risk assessment is carried out. And a substantial majority of small planes are flown for recreational purposes, and pilots enjoy flying lower, where they can see things below them. Interpret F.N. Electrical anti-ice is operated for all flight operations to inhibit ice build up. How do wheelchair users get on airplanes? In 1965 the idea was further developed by combining the inflatable slide with an integrated raft. It is proposed that catering of the new Airbus A380 can be carried out via upper deck doors. 14 Signals in use for door opening procedures vary at UK airports and between aircraft operators. Use of the aircraft attachment points may be used as a means of averting damage to the aircraft door frames and other important parts. Such nets or restraint systems must be adequately tested and secured. It all makes sense when you know the reasons for it! (4) Type IV. Gravity will then pull the slide to the ground and it will inflate. Aircraft doors refer to passenger doors, cargo doors and ground service access doors to various areas of the fuselage. During transit or during maintenance visits, the aircraft doors may need to remain open for a number of reasons. Various forms of indicators, such as lights, flags and pins with ribbons are used to indicate an armed condition.[10]. 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. 39 Doors should only be opened by door trained personnel. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft 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. 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. 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. Cabin Door Safety Strap 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. Anyway, I was curious about the ground height of the 757 in relation to the 737. 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. 19 Where an air bridge is used the risk of a fall is minimised. Approximately how high is the bottom of the cabin door from the ground? More specifically, they are smaller than 25 inches. Airliners.net is the leading community for discovering and sharing high-quality aviation photography. Passenger The failure to undertake a risk assessment should be dealt with by reference to the EMM. When activated, how long should the Emergency Lights last? Flight 1603 went back to the gate and was taken out of service. Typically, this will involve providing guarded access equipment and fall protection equipment. Heads up this was for Grand Forks Flight Support who will be handeling a SunCountry 737-800 charter for UND Fighting sioux football tomorrow. 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. 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. Because of the accidental emergency slide deployment that followed, the flight ended up being delayed for seven hours. a. An airplane altimeter is a gauge that indicates the height of the plane above the ground. This costs the industry millions in lost revenue every year, estimated at $20 million in North America by cabin crew alone.[12]. The Boeing spec sheet lists 9'-00" at OEW and 8'-06" at MTW for a B738. by users, inspections by competent persons, as well as any statutory inspections required by Lifting Operations and Lifting Equipment Regulations (LOLER). How do I report Air Carrier Access Act violations? I hope this has not already been discussed. Plus if a plane goes higher, it has to burn more fuel in order to get there. Airport overviews from the air or ground, Tails and Winglets I did a search, but returned nothing. The CO2 is used to slow down the rate at which the valve expends the gases. 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. Another unique type of evacuation slide is found on the DC-9 family of aircraft and its successors the MD-80 and Boeing 717. 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. Access to high loader vehicles or other access equipment should be restricted to authorised personnel and it should be clearly indicated that access is not allowed to unauthorised personnel such as other ground support workers or flight crew. Commercial airplanes can theoretically fly a little higher than this, and of course they can also fly lower if they choose to. 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. Aircraft Cargo Door Opening/Sill Details for Ground Support Equipment Interface AIR1673B . 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. 14) BS EN 12312 Aircraft ground support equipment - specific requirements: Part 8: maintenance stairs and platforms - due for publication. However, for all the reasons mentioned above, this is mainly theoretical, and most commercial airplanes fly much lower than this. 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. These procedures are usually placarded red on the slide, "For Ditching Use Only". Latch-on guarantees fore and aft and vertical alignment of the loader bed with the aircraft doorway, when used in . 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. CV jumbo Assuming radial entry flow, determine the theoretical values for (a) the flow rate and (b) the power. They should also have sufficient authority to take any necessary action if a situation of imminent danger is identified. That's quite high due to the 747 cockpit location on the upper deck. 6). Parking the plane. The 787-8 is equipped with eight passenger entry and will not operate, as the system is disabled by the aspirators on the slide taking in water. 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). 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. foward galley cabin circuit breaker panel. 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. 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. 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. Again, airliners can generally cope with turbulence, but it is preferable to avoid it if possible. 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. Both slides and slide/rafts use non-explosive, inert gas inflation systems. Which of the External Lights will automatically turn off when the landing gear is retracted, regardless of the position of their control switch? 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 there are good reasons for how high planes fly. Waste tank negative pressure is provided by cabin differential air when the aircraft is above ______. A fueling control panel don't know about the 757, but those 737 engines are darn low..I love the way they look though!!! A bit out of topic, but since the 757 and 737 have the same fuselage width, do they share any similar parts? Batteries that appear to be damaged or leaking may be removed and separately packaged by the carrier. Employees using fall protection equipment should be trained in its safe use, including user equipment checks. What does this mean emulate what you respect in your friends? As soon as a plane lands and clears the active runway, the pilots receive taxi instructions from ground controllers. Door status is indicated on the ECAM DOOR page. 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. height: 12'5 - 3.79 mtr max. Fuel Receptacle 11 There are 3 main types of aircraft door: 3) Upper deck doors (emergency evacuation). 49 Documents which give general advice on working at heights are listed at Appendix 1 . Planes flying in approximately westerly directions have to fly at even altitudes. We have established the mechanical means by which aircraft doors are kept shut, but there is another aspect to consider. The airplane has been engineered to have essentially the same landing characteristics as the 777-200LR (Longer Range), despite a maximum landing weight that is nearly 17 percent heavier (575,000 pounds; 260,810 kilograms). Depending on Aircraft Gross weight and strut compression, the After all, inward-opening cargo doors would reduce the available space for a freight aircraft's goods. They rarely ask about it, or want to know what altitude is used. 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. 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. There should also be a suitable procedure for the closing of the door and retraction of the air bridge. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft Passing through an aircraft door represents the start or end of one's time onboard an aircraft. A farmer has 19 sheep All but 7 die How many are left? Further guidance is also contained in various British and European standards on which the Transportation Section can advise. 40 Fall restraint equipment should be inspected and maintained according to relevant manufacturers recommendations. 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. Table 1: Risks of serious injury requiring immediate action, including consideration of a Prohibition Notice. Engine anti-ice is supplied to the _______. The troposphere is usually said to finish at 36,000 feet. This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. What is the moral lesson of at wars end by rony diaz? 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. Which electrical bus provides the power to charge the Internal Batteries for the Emergency Light System? Your reliance on this aircraft size information is at your own risk. 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. If the door is opened in emergency mode at an abnormal attitude (e.g. All large commercial aircraft have escape slides on the main doors but some also have slides for exits over the wings. It also made inspection and work on the engines very easy. HSE aims to reduce work-related death, injury and ill health. Can I check my wheelchair at the boarding gate? 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. 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. Planes flying eastward, including northeast and southeast, will fly at odd altitudes, such as 35,000 feet. Cabin / Interior Dimensions: Cabin / Interior Width: 120.1 to 122.5 inches (approximate) Cabin / Interior Height: 83 inches +- approximate. 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. Potassium 2.Smmol/L \ Check these cargo hold dimensions! Commercial airplanes usually fly above the troposphere, which is the part of the atmosphere where weather events usually happen. Canvas type slides are still found on some out of production Russian aircraft. A centrifugal pump has the following dimensions: d2 = 42 cm, L = 5 cm, and $\beta 2=33^{\circ}$. With this much traffic, there has to be some official arrangement to make sure collisions do not happen, and there is. 5) the duration of the work and the location in which it is carried out. The left wing has During test flights this maximum is exceeded slightly to verify the that airplane remains safe should it have cause to ascend from that limit. If the STROBE switch is in AUTO, the strobe will operate ________. 42 The Work at Height Regulations 2005 address all work at height where a person could fall a distance liable to cause personal injury. FUEL RECEPTACLE GROUND HEIGHT When on Battery Power, which Dome light can be turned on? These types of aircraft have a door sill height greater than 2,0 m (80 in) above the ground. Here are the 10 steps from arrival to take-off: 1. The Fuel Quantity Display is located on the ________. 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. 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. stairs and bridges are common with 767 and This is why when you are on a long flight, you will . [9] Certain slides on board the aircraft have the Tribrid Inflation System, which is connected to a sensing system within the door. Hope this helps. It can be installed as a stand-alone unit or integrated into the aircraft systems and powered from aircraft power. 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) . This may, for example, involve lifting up the flap on the girt bar, and pulling the detach handle. Therefore small planes generally fly between 2000 and 10,000 feet. Doors should never be left unprotected once open. Aircraft General DIMENSIONS Width : 35.79 m Lenght : 39.5 m . Airliners.net is the leading community for discovering and sharing high-quality aviation photography. [6], There are four types of inflatable aircraft evacuation aid covered by EASA Technical Order:[7]. Ground to underbelly is 226 to 246 cm on SP.
