Airliners.net is the leading community for discovering and sharing high-quality aviation photography. There should be checks of all equipment (vehicles, platforms, guard rails, harnesses, etc.) It is not essential for aircraft to avoid bad weather, but it is a good idea. A device can be used to prevent this problem. 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. 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. Assuming radial entry flow, determine the theoretical values for (a) the flow rate and (b) the power. Indeed, a similar situation befell another PIA aircraft in 2019. In such cases, safety equipment must be used and certain precautions followed. I did a search, but returned nothing. According to Quora user and aircraft maintenance engineer Jan Krusat, the makeup of the 767's design team played a key role. 777 airplanes. It rotates at 1200 rpm, and the head generated is 52 m of water. 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. This is why when you are on a long flight, you will . Once made of steel, most cylinders now are made of aluminum or alloy cores wrapped with fiberglass, or other lightweight, fuel saving materials. Both military and civil versions, Blimps / Airships Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes Potable Water pressure is provided by _________. This should be considered as a strategic factor for the purposes of the EMM. Planes flying in approximately westerly directions have to fly at even altitudes. 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). These are usually cylindrical, hollow aluminum tubes with sliding cylindrical or internal flapper doors that open when high pressure gas is applied, and close when the gas stream subsides and the internal slide back pressure reaches about 2.5 - 3.0 psi. 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. Typically, overwing evacuation slides are not designed for use in ditching situations as they cannot be detached. Canvas type slides are still found on some out of production Russian aircraft. Specifically, several members of this group were former McDonnell Douglas engineers. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft 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. However, it is important to note that this only tends to be the case on passenger aircraft. 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. Did you know how aircraft doors worked? 23 Clear procedures and means of communication should also be in place for removal of aircraft steps. Independent of the inflation system, all slides are equipped with at least one pressure relief device per inflation chamber. 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. [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. Depending on Aircraft Gross weight and strut compression, the Posted on August 27, 2021 - 5 minute read. To meet this, all evacuation units need to deploy in less than 10 seconds. . What are the names of the control laws that are used to operate the flight controls? 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. 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.

It can signify the optimism of beginning a new trip, or the excitement of having arrived somewhere new, or welcomingly familiar. 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. Clear procedures and signals should be used to open the door. Are airplane bathrooms wheelchair accessible? Use of the aircraft attachment points may be used as a means of averting damage to the aircraft door frames and other important parts. This costs the industry millions in lost revenue every year, estimated at $20 million in North America by cabin crew alone.[12]. foward galley cabin circuit breaker panel. Large . Door status is indicated on the ECAM DOOR page. The 787-8 is equipped with eight passenger entry Whereas, I think the 737 looks very short and squatty. Note that powered wheelchairs with a reclining seatback often require much more significant disassembly. 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. However, a planes engines need oxygen in order to function, so flying too high can also cause problems. Typically, aircraft fly around 35,000 or 36,000 feet above sea level. 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. What is the normal configuration for switches and lights on the A320? Today some of the corporate jets can fly at 51,000 feet. 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. 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. Once the bridge is positioned communication between cabin crew and ground handlers is paramount. Older slides are yellow and made of neoprene/nylon fabric. During test flights this maximum is exceeded slightly to verify the that airplane remains safe should it have cause to ascend from that limit. Representatives of airlines, airports and ground handlers have worked with HSE in the development of this guidance. and will not operate, as the system is disabled by the aspirators on the slide taking in water. State the rationale for any abnormalities and identify any treatment needed. 8) Mobile elevating work platforms - User safety guide. The aircraft was on the ground at the time of the incident. Some Russian-built aircraft like the Tupolev Tu-154 have a very complicated process to activate and deploy the slides. Chloride 103 mEq/L \ These types of aircraft have a door sill height greater than 2,0 m (80 in) above the ground. Where attachment points are on guard rails, the rails must be of sufficient strength to withstand foreseeable forces. **Laboratory Testing**\ Taking the FWD entry door sill height as an example. 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. Be sure to read my blog post on how to prevent damage to power wheelchairs on airplanesand also the FAQ article, 4 ways to prevent wheelchair damage in air travel. This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. Particularly a SunCountry 737-800 ? 19 Where an air bridge is used the risk of a fall is minimised. 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. Tail and Winglet closeups with beautiful airline logos. The 757 sits very high, making it, I think, much more imposing looking.

All a snowbound skier had to cat were walnuts! If not. Heads up this was for Grand Forks Flight Support who will be handeling a SunCountry 737-800 charter for UND Fighting sioux football tomorrow. The CO2 is used to slow down the rate at which the valve expends the gases. He was carrying a bag holding 12 dozen nuts. Wind will determine how fast the aircraft is travelling across the ground on touchdown and how long it will need to brake thereafter. One of the newest developments in evacuation slide technology can be found on the Airbus A380, which was developed by Goodrich Aircraft Interior Products. 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. 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. TRUE/ FALSE. What is the height from the ground to the bottom of the cargo door on a KC-135? Another unique type of evacuation slide is found on the DC-9 family of aircraft and its successors the MD-80 and Boeing 717. Glucose 202 mg/dL \ However, legally planes must be at least 1000 feet above any object on the ground, and must be able to land clear of any congested area in the event of an engine failure. On February 9, 2020, a British Airways Boeing 747-400 broke the New York-London subsonic airliner speed record in 4 hours 56 minutes, pushed by the . This will require specific training to be provided for each type of vehicle, equipment, guarding system or fall restraint system used. Most airline passengers simply accept the fact that passenger jets fly very high. If the door is opened in emergency mode at an abnormal attitude (e.g. Which electrical bus provides the power to charge the Internal Batteries for the Emergency Light System? [4] Today Air Cruisers is part of Zodiac Aerospace and ultimately owned by Safran who are the world's largest provider of evacuation slides. 36 Users should be instructed in the use and limitations of access equipment, and the limits on their authority to modify it. Cabin / Interior Dimensions: Cabin / Interior Width: 120.1 to 122.5 inches (approximate) Cabin / Interior Height: 83 inches +- approximate. HSE aims to reduce work-related death, injury and ill health. We have established the mechanical means by which aircraft doors are kept shut, but there is another aspect to consider. 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. Views from inside the cockpit, Aircraft Cabins Because of the accidental emergency slide deployment that followed, the flight ended up being delayed for seven hours. When the door is placed in the armed position, the device is armed. 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. This sort of thing is extremely unlikely, but it does happen occasionally. So there has to be a balance, which is the reason for the fairly specific altitudes generally used by airliners. This protects the chamber from catastrophic failure due to over pressurizing. Cabin Door Safety Strap How do I report Air Carrier Access Act violations? 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. The LDG LT memo displays on the ECAM when ______. Window exits usually come in two configurations: Window exits are usually equipped with ditching or life lines. I know they had smaller engines, but surely that fuselage must've been really close to the ground?. Which color illuminates in a switch to inform the crew that a system is available? 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. Prior to departure (usually before engine startup), all the aircraft doors are placed into the armed (or automatic) mode by the cabin crew. 15 Aircraft doors should only be operated by door trained personnel such as trained ground staff, cabin crew, engineers or other competent workers. [6], There are four types of inflatable aircraft evacuation aid covered by EASA Technical Order:[7]. Potassium 2.Smmol/L \ 1 While the numbers of falls from height reported to HSE at airports has decreased significantly over recent years, there is a potential for serious injury if safe systems of work and standards are not maintained. All Rights Reserved. The main reason for airliners flying so high is that it saves fuel and therefore saves money, which is always a priority for airlines. There should also be a suitable procedure for the closing of the door and retraction of the air bridge. Both MUST be fully conversant with the signals or codes to be used. (4) Type IV. There are also half-tie restraints which keep the inflating slide from drooping or blowing under the aircraft. . One end has a buckle to connect to attachments on the aircraft's wings. A farmer has 19 sheep All but 7 die How many are left? Airport overviews from the air or ground, Tails and Winglets In 1965 the idea was further developed by combining the inflatable slide with an integrated raft. Seeing a gap in the market for a regional aircraft with mainline capabilities, we launched the E190. This is all in addition to any maintenance that is specified by the manufacturer. For B767-200 the answer is from 4.14m to 4.50 (height to the door, not strictly the cockpit, for which max and min should be slightly more extreme due to distance from centre of Continue Reading 10 Commercial airplanes usually fly above the troposphere, which is the part of the atmosphere where weather events usually happen. This is rarely used however, because the lanyard attached to the handle runs through the girt to the valve, which is several inches too short when the girt is extended fully. Also, most small planes are not equipped with oxygen, which would be necessary if they were to fly too high. They rarely ask about it, or want to know what altitude is used. Fuel During transit or during maintenance visits, the aircraft doors may need to remain open for a number of reasons. They are usually about the same width and height as a seat. What are the TSA security procedures for wheelchair users? Aircraft doors are designed to be used on the ground, where they are not subjected to the pressure difference found at altitude. 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. Tests in 25-knot (46km/h) cross winds have shown these deployment systems to be very effective. Once the slide is separated, the slide remains attached to the aircraft by a mooring line. 3) the work that is being done, for instance whether it involves handling awkward or heavy loads, the suitability of platform or step design.
