The troposphere is usually said to finish at 36,000 feet. 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. When removing the battery is necessary, carriers must remove and package the battery in carrier-provided packaging, if asked to do so by the passenger. Plus if a plane goes higher, it has to burn more fuel in order to get there. 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. [6], There are four types of inflatable aircraft evacuation aid covered by EASA Technical Order:[7]. 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. 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. 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. 35 People positioning, using and supervising the use of vehicles and other access equipment should be competent to undertake this work safely. 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. Noah's ark of the skies: Big or small, domesticated or not, Cargolux has solid expertise in transporting live animals across the world. I did a search, but returned nothing. . height: 12'5 - 3.79 mtr max. I'm surprised to see the door height of the 732 even lower than that of the 733/4! Last month, a DHL Boeing 757's cargo door opened inflight in Germany, although, thankfully, the aircraft was able to land safely and without injuries to its crew. Flight 1603 went back to the gate and was taken out of service. The air becomes thinner as the altitude increases, and thin air creates less drag on the aircraft. Each nut that was opened resulted in one kernel and two shell halves. They rarely ask about it, or want to know what altitude is used. We thank you for your support and hope you'll join the largest aviation community on the web. 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. 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. In such circumstances the use of personal fall protection equipment connected to a suitable anchorage point may be an acceptable solution, if there are no alternative means of protection. and will not operate, as the system is disabled by the aspirators on the slide taking in water. On an aircraft without a Live TV Master Power Switch, how many circuit breakers should be pulled in the event of a fire? Piston engines do not operate well in thin air, and this is one of the reasons why most small planes fly at altitudes of below 15,000 feet. Sets found in the same folder A320/321 Oxygen Specifically, several members of this group were former McDonnell Douglas engineers. Thanks guys. AASI JETCRUZER. 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. If not. Batteries that appear to be damaged or leaking may be removed and separately packaged by the carrier. 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. The flight took off once all . 39 Doors should only be opened by door trained personnel. These include the Boeing 767, Boeing 757, and Airbus A320-series aircraft. Aircraft ground equipment Passenger boarding bridge or transfer vehicle Requirements for interface with aircraft doors. The IATA Airport Handling Manual 29th edition 2009 AHM 430 recommends that cabin access doors, ie passenger entrance and service doors, shall be operated by specially trained and qualified staff either inside or outside the aircraft, as instructed by the carrier. 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. AIRCRAFT MODEL: WINGSPAN: . But there are good reasons for how high planes fly. The next widebody, DC-10 can be found at Everything from the Goodyear blimp to the Zeppelin, Night Photos (Maximum 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. Specific requirements for different types of GSE are in BS EN 12312 (see Appendix 1 ). 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. However, such doors do sometimes find themselves unintentionally open. This will require specific training to be provided for each type of vehicle, equipment, guarding system or fall restraint system used. Flying higher means that commercial airplanes can avoid most other airborne traffic. 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. Several factors contributed to the 767's doors having different operational characteristics to other aircraft. But in fact, small aircraft generally fly much lower than that for a variety of other reasons. All large commercial aircraft have escape slides on the main doors but some also have slides for exits over the wings. The . These may be attached to the inside frame of the window exit, or located in a nearby storage locker. The 777F accommodates 27 standard pallets (96 by 125 inches; 2.5 by 3.1 meters) on the main deck. The Boeing 737 is designed to fill the smaller jet airliners space over a given range of seats. These procedures are usually placarded red on the slide, "For Ditching Use Only". For thee A320, what is the "Minimum Theoretical Pavement Width for a 180 degree turn? Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft Interpret F.N. So again, there has to be a balance, which accounts for the altitudes generally used. (Continue to next page) Where attachment points are on guard rails, the rails must be of sufficient strength to withstand foreseeable forces. 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. There should also be a suitable procedure for the closing of the door and retraction of the air bridge. 40 Fall restraint equipment should be inspected and maintained according to relevant manufacturers recommendations. TRUE/FALSE. 15 Aircraft doors should only be operated by door trained personnel such as trained ground staff, cabin crew, engineers or other competent workers. 11 There are 3 main types of aircraft door: 3) Upper deck doors (emergency evacuation). [1] To reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. 48 Specific guidance on the roles and responsibilities of those involved in aircraft turnround is given in Aircraft Turnround HSG209. 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. At about the same time, a metal pin that holds the center of the Valise closed is also pulled, releasing a daisy chain and the two halves of the cover. 42 The Work at Height Regulations 2005 address all work at height where a person could fall a distance liable to cause personal injury. Slides fitted by main fuselage doors are mounted on the door itself. The aircraft is equipped with ____ cabin doors. All a snowbound skier had to cat were walnuts! Which SSR code describes my disability assistance needs? Where is the control switch for the Standby Compass Light? Which of the External Lights will automatically turn off when the landing gear is retracted, regardless of the position of their control switch? HSE aims to reduce work-related death, injury and ill health. [4] Today Air Cruisers is part of Zodiac Aerospace and ultimately owned by Safran who are the world's largest provider of evacuation slides. 10 Some airlines have already introduced door nets to protect against falls from open doors. Here are the 10 steps from arrival to take-off: 1. Independent of the inflation system, all slides are equipped with at least one pressure relief device per inflation chamber. According to Ask The Pilot, aircraft doors are held in place physically by "a series of electrical and/or mechanical latches." After all, inward-opening cargo doors would reduce the available space for a freight aircraft's goods. 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. receptacle ground height for the 787-8 and other We thank you for your support and hope you'll join the largest aviation community on the web. 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. Aircraft doors are designed to be used on the ground, where they are not subjected to the pressure difference found at altitude. -N60659 RE: Question About 737 Door Height From Ground #4427985 This packaging is normally inside in a slide bustle, a protruding part on the inside of an aircraft door that varies with aircraft size, door size and door location. Instead the precautions will be identified solely on the basis of an assessment of the risks involved. two cargo doors on the right side, and one bulk 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. 787-8 DOOR LOCATIONS AND DIMENSIONS 2) the availability and adequacy of any existing fall protection measures including guarding and personal fall protection systems. (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.). Both MUST be fully conversant with the signals or codes to be used. 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. Wind will determine how fast the aircraft is travelling across the ground on touchdown and how long it will need to brake thereafter. Engine anti-ice is supplied to the _______. The slides are stored in cabinets usually beside the emergency exit inside the aircraft. It also made inspection and work on the engines very easy. When activated, how long should the Emergency Lights last? 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. Such incidents are rare, but not completely infrequent. Particularly a SunCountry 737-800 ? This incident occurred due to a passenger on the 777 mistaking the door for a bathroom while on the ground in Manchester. 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. It can signify the optimism of beginning a new trip, or the excitement of having arrived somewhere new, or welcomingly familiar. 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. 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. Whereas, I think the 737 looks very short and squatty. 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 assessment should recognise the potential for serious injury arising from low falls as well as high falls. 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). Again, airliners can generally cope with turbulence, but it is preferable to avoid it if possible. Turbulence is less common at high altitudes too. We have established the mechanical means by which aircraft doors are kept shut, but there is another aspect to consider. 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. Specific guidance on safe access to aircraft during maintenance is in SIM 05/2002/52; guidance on safe access for catering activities and use of high loaders is in SIM 05/2008/02. Door status is indicated on the ECAM DOOR page. Will my power wheelchair fit on the airplane? Because of the accidental emergency slide deployment that followed, the flight ended up being delayed for seven hours. Fuel receptacle ground height for the 787-8 and other Boeing airplanes is shown in figure 7. Table 1: Risks of serious injury requiring immediate action, including consideration of a Prohibition Notice. They work on the Venturi principle, and draw outside air into the evacuation unit at a rate of about 500:1. This is not a factor in commercial flying. There are also half-tie restraints which keep the inflating slide from drooping or blowing under the aircraft. Also, most small planes are not equipped with oxygen, which would be necessary if they were to fly too high. Door straps on many aircraft are simply a warning device and are not fall protection systems. Over 42,000 flights take place every day, with 5,000 planes in the sky at any one time, according to the FAA. Well the low ones are a lot easier to load without. 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. Airplanes such as the Embraer 145 family, Fokker 50 family, Antonov An-148 family, ATR family and the Bombardier CRJ family do not have escape slides because all exits are at a distance from the ground (less than 6 feet (1.8m)), below which evacuation assisting devices are not required by regulations. 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. 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. Taking the FWD entry door sill height as an example. Other means of access includes service vehicles such as catering high loaders. Assuming a 3,730-U.S. gallon (14,120-liter) Some Russian-built aircraft like the Tupolev Tu-154 have a very complicated process to activate and deploy the slides. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft This is all in addition to any maintenance that is specified by the manufacturer. I hope this has not already been discussed. 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. Procedures may also include a count down before opening the door. Where are the Live TV circuit breakers located? 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. 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. So there has to be a balance, which is the reason for the fairly specific altitudes generally used by airliners. It is probably not really safe for them to be much above 10,000 feet. To compensate for any wind, new evacuation slides contain internal baffles, which cause the ends nearest the aircraft to inflate first, which are constructed to come out like four elbows and press against the fuselage of the aircraft to the forward and aft sides of the exit door. 46 The roles and responsibilities of HSE and CAA and a framework for liaison are outlined in a Memorandum of Understanding (MoU) to ensure coordination of policy issues, enforcement activity and investigation in respect of aircraft and the systems in which they operate.
