Airport overviews from the air or ground, Tails and Winglets 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. 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. This is a major inconvenience, as it can disrupt your travel plans. Which display unit shows the Engine/Warning Display (E/WD)? 6). There should be checks of all equipment (vehicles, platforms, guard rails, harnesses, etc.) But in fact, small aircraft generally fly much lower than that for a variety of other reasons. with the appropriate length fuel line that can 38.70 m / 127 ft 0 in Overall length 29 These doors should only be used for emergency evacuation. 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. In addition, jet engines operate more efficiently at high altitudes, meaning the plane can travel faster while at the same time burning less fuel. Aircraft painted in beautiful and original liveries, Airport Overviews I know they had smaller engines, but surely that fuselage must've been really close to the ground?. Carriers may require that passengers wishing to have battery powered wheelchairs transported on a flight check-in one hour prior to scheduled departure. Everything from the Goodyear blimp to the Zeppelin, Night Photos There are a number of Annexes to the MoU on specific areas. The airline released a statement on . 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) . Planes flying in approximately westerly directions have to fly at even altitudes. This will require specific training to be provided for each type of vehicle, equipment, guarding system or fall restraint system 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. (4) Type IV. The inflation system usually consists of a pressurized cylinder, a regulating valve, two high pressure hoses and two aspirators. How can I reduce the risk of my wheelchair being damaged? Other means of access includes service vehicles such as catering high loaders. 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). 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. Your reliance on this aircraft size information is at your own risk. Beautiful shots taken while the sun is below the horizon, Accidents Airline personnel can assist you with this, if you bring the tools (typically a small wrench to loosen bolts) with you. Aircraft doors are designed to be used on the ground, where they are not subjected to the pressure difference found at altitude. The main reason for airliners flying so high is that it saves fuel and therefore saves money, which is always a priority for airlines. The aircraft is equipped with ____ cabin doors. It can signify the optimism of beginning a new trip, or the excitement of having arrived somewhere new, or welcomingly familiar. What does this mean emulate what you respect in your friends? 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. 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 altitudes they use, there will be no light aircraft and helicopters, and no drones, which all fly much lower. Cabin Door Safety Strap is installed in the left wing only. Particularly a SunCountry 737-800 ? This is one way in which they are kept secure despite the strong forces that aircraft encounter inflight. 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. 10 Some airlines have already introduced door nets to protect against falls from open doors. 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. 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. Doors Dimensions: Main Entry Door (front right): 34 by 72 inches Modern planes often indicate an armed condition with an indicator light. This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. A farmer has 19 sheep All but 7 die How many are left? They should also have sufficient authority to take any necessary action if a situation of imminent danger is identified. 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. Wing Anti-ice is operated in flight when required by icing conditions, but can also be operated for ______ on the ground for testing purposes. The assessment should recognise the potential for serious injury arising from low falls as well as high falls. 65 Requirements of the Air Navigation Order should be taken into consideration, in relation to the requirements to avoid endangering an aircraft or compromising aircraft or flight safety. Slides fitted by main fuselage doors are mounted on the door itself. 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. 35 to 60 minutes, depending on the fuel pressure. In particular aircraft structures and components are subject to stringent design requirements, and attachment points can only be provided according to manufacturer's specifications and approval. And a substantial majority of small planes are flown for recreational purposes, and pilots enjoy flying lower, where they can see things below them. Before removing GSE the Equipment operator must ensure that the door has been closed and secured by an authorised person, or that a clearly visible safety device has been placed across the opening. The following conditions are outlined by the ACAA regarding the carriage of a power wheelchair or scooter: If you arent sure how to disassemble your wheelchair, contact your local wheelchair supplier or reach out to the manufacturer. 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. As the larger member of the A220 Family, the A220-300 is perfectly tailored for the 120-160 seat market. Ground to underbelly is 226 to 246 cm on SP. [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. 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. 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. 39 Doors should only be opened by door trained personnel. The Boeing 737 is designed to fill the smaller jet airliners space over a given range of seats. Latch-on guarantees fore and aft and vertical alignment of the loader bed with the aircraft doorway, when used in . But there are good reasons for how high planes fly. They rarely ask about it, or want to know what altitude is used. book answer is 10 feet. All Rights Reserved. On the other hand, flying too high could have negative safety issues. Tail and Winglet closeups with beautiful airline logos. 42 The Work at Height Regulations 2005 address all work at height where a person could fall a distance liable to cause personal injury. HSE aims to reduce work-related death, injury and ill health. 1) The Work at Height Regulations 2005 SI 2005 No735, 2) SIM 05/2002/52 - Safe external access and working platforms at aircraft during maintenance, 3) SIM 05/2008/02 - Safe access to aircraft for catering operations, 5)OC 282/30- Inspection of fall arrest equipment made from webbing or rope, 6) OC 234/11 - Lifting Operations and Lifting Equipment Regulations 1998, 7) INDG 367 Inspection of fall arrest equipment made of webbing or rope. Most airline passengers simply accept the fact that passenger jets fly very high. [8] Even where only a Type I slide is fitted it has sufficient buoyancy to act as an aid in the event of a water landing. Can the aircraft be flown with the Cabin Surveillance System (CSS) inoperative? Glucose 202 mg/dL \ Planes flying eastward, including northeast and southeast, will fly at odd altitudes, such as 35,000 feet. 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. Further guidance is also contained in various British and European standards on which the Transportation Section can advise. Most of the time, flight attendants seamlessly operate these structures. The failure to undertake a risk assessment should be dealt with by reference to the EMM. Beautiful shots taken while the sun is below the horizon, Accidents Pictures of great freighter aircraft, Government Aircraft Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft Clear procedures and signals should be used to open the door. The flight took off once all . As soon as a plane lands and clears the active runway, the pilots receive taxi instructions from ground controllers. 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. Figure 7. 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 . 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. Passing through an aircraft door represents the start or end of one's time onboard an aircraft. During test flights this maximum is exceeded slightly to verify the that airplane remains safe should it have cause to ascend from that limit. 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. For further information on the MoU, see Appendix 1 guidance and reference material. Note that powered wheelchairs with a reclining seatback often require much more significant disassembly. 26 Once an aircraft door is open and guarded steps are in position, the access may be used by authorised cleaners, security, airline employees, or passengers as necessary without risk of falls from unguarded edges. 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. There should also be a suitable procedure for the closing of the door and retraction of the air bridge. 5) the duration of the work and the location in which it is carried out. Stay informed:Sign up for ourdailyandweeklyaviation news digests! Sodium 138 mEq/L \ 9 Airlines have the ultimate responsibility for procedures for opening their aircraft doors. This may mean modifying the equipment or using fall restraint equipment in the short term. 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. 5 All Ground Support Equipment (GSE) should be designed in accordance with BS EN 1915 -1:2001 Aircraft GSE - General safety requirements Part1: Basic safety requirements, and the relevant parts of BS EN 12312 - Specific requirements. Typically, overwing evacuation slides are not designed for use in ditching situations as they cannot be detached. The gauge works based on air pressure, according to the formula h = 18 400 log, where h is the height above the ground in metres, P is the air pressure at height h, and P is the air pressure at ground level. 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 sort of thing is extremely unlikely, but it does happen occasionally. That's quite high due to the 747 cockpit location on the upper deck. Can I check my wheelchair at the boarding gate? Fuel What is the height from the ground to the bottom of the cargo door on a KC-135? Once the bridge is positioned communication between cabin crew and ground handlers is paramount. Such incidents are rare, but not completely infrequent. . What is the condition of the Slide Arming Lever when the yellow arm plate is down and flush with the door? Various forms of indicators, such as lights, flags and pins with ribbons are used to indicate an armed condition.[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. Instead the precautions will be identified solely on the basis of an assessment of the risks involved. So again, there has to be a balance, which accounts for the altitudes generally used. for 500 U.S. gallons per minute (1,893 liters per Training should include aircraft manufacturers requirements, awareness of emergency chute operation and deactivation and risk of falls. Aircraft Ground Services - ground support services such as ground power and aircraft environmental control (heating/cooling) are often built into the PBB eliminating the need for mobile equipment Disadvantages and Risk The major risk associated with use of a Passenger Boarding Bridge is aircraft damage. Thankfully, the nature of physics renders this task impossible. 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. 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. Airport overviews from the air or ground, Tails and Winglets Birds rarely fly that high, which is important, as bird strikes, though rare, can be disastrous if they happen. Once the slide is separated, the slide remains attached to the aircraft by a mooring line. This incident occurred due to a passenger on the 777 mistaking the door for a bathroom while on the ground in Manchester. Depending on Aircraft Gross weight and strut compression, the 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. Large . Aircraft doors refer to passenger doors, cargo doors and ground service access doors to various areas of the fuselage. 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. So there has to be a balance, which is the reason for the fairly specific altitudes generally used by airliners. 18 Passenger doors may be accessed via air bridges, mobile access steps or integral aircraft steps. The highest certified altitude of an airliner was Concordes 60,000 feet. 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. Our site uses cookies. It rotates at 1200 rpm, and the head generated is 52 m of water. 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. 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. 25 These are part of the aircraft structure and are invariably operated by the cabin crew. Procedures may also include a count down before opening the door. The CO2 is used to slow down the rate at which the valve expends the gases. 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. What is the reason for the low ride height of the 737, as I think it limits the length the fuselage can be stretched? Commercial airplanes can theoretically fly a little higher than this, and of course they can also fly lower if they choose to. Aircraft doors are designed to be used on the ground, where they are not subjected to the pressure difference found at altitude. It all makes sense when you know the reasons for it! 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. Question About 737 Door Height From Ground, RE: Question About 737 Door Height From Ground, http://www.boeing.com/assocproducts/aircompat/acaps/737sec2.pdf. Turbulence is less common at high altitudes too. What are the names of the control laws that are used to operate the flight controls? With this much traffic, there has to be some official arrangement to make sure collisions do not happen, and there is. 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. To be suitable the assessment should consider the issues identified above. 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. [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. I did a search, but returned nothing. Short hops or longer routes - the E190 has the versatility to go the distance. 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. These procedures are usually placarded red on the slide, "For Ditching Use Only". Boeing 747 Tail Height. 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. How to request wheelchair assistance at the airport? 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. In the longer term we should be asking companies to come up with a programme and timetable for replacement or improvement of equipment where necessary. 2 Risks arise during maintenance of aircraft and during servicing and turnaround activities. Data not published, based on our estimates, center aisle. 48 Specific guidance on the roles and responsibilities of those involved in aircraft turnround is given in Aircraft Turnround HSG209. Each nut that was opened resulted in one kernel and two shell halves. The high pressure of the cabin forces the wedge-shaped, plug-like door into its socket. Check these cargo hold dimensions! Specifically, several members of this group were former McDonnell Douglas engineers. Anyway, I was curious about the ground height of the 757 in relation to the 737.
