Window exits usually come in two configurations: Window exits are usually equipped with ditching or life lines. Sodium 138 mEq/L \ Commercial airplanes can theoretically fly a little higher than this, and of course they can also fly lower if they choose to. The left wing has It also made inspection and work on the engines very easy. If the door is opened in emergency mode at an abnormal attitude (e.g. However, for all the reasons mentioned above, this is mainly theoretical, and most commercial airplanes fly much lower than this. foward galley cabin circuit breaker panel. 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. We thank you for your support and hope you'll join the largest aviation community on the web. 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. Our large helicopter section. Therefore small planes generally fly between 2000 and 10,000 feet. Your reliance on this aircraft size information is at your own risk. receptacle ground height for the 787-8 and other The practice of differentiating between the precautions required for high falls and low falls will no longer apply. 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. Posted on August 27, 2021 - 5 minute read. 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. They rarely ask about it, or want to know what altitude is used. Various forms of indicators, such as lights, flags and pins with ribbons are used to indicate an armed condition.[10]. It also minimizes the risk of accidental opening. 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. There are a number of Annexes to the MoU on specific areas. Typically, this will involve providing guarded access equipment and fall protection equipment. Cabin Door Safety Strap State the rationale for any abnormalities and identify any treatment needed. On the ground, the packs can receive compressed air from a ________, the APU, or the engines. 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. .

Where attachment points are on guard rails, the rails must be of sufficient strength to withstand foreseeable forces. 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. Parking the plane. But there are good reasons for how high planes fly. 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. It works by sounding an audible alert (voice) when the door operator, whether trained or not, is about to open the door in the armed position. 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). Airliners.net is the leading community for discovering and sharing high-quality aviation photography. As soon as a plane lands and clears the active runway, the pilots receive taxi instructions from ground controllers. The entire, self-contained slide pack is approximately 3ft (0.91m) wide, 2.5ft (0.76m) long and about 1ft (0.30m) high, depending on aircraft type. This sort of thing is extremely unlikely, but it does happen occasionally. Stay informed:Sign up for ourdailyandweeklyaviation news digests! As the thread title says - anyone know how high the door of a 737 is off the ground? 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. 2) the availability and adequacy of any existing fall protection measures including guarding and personal fall protection systems. Most of the time, flight attendants seamlessly operate these structures. 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). 38.70 m / 127 ft 0 in Overall length 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? What does this mean emulate what you respect in your friends? 3 Risks to ground handlers and aircraft crew have been identified during opening of the aircraft door, when the door must be cracked and then opened, sometimes swinging out from the aircraft body. A groundbreaking concept in the air. 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. 20 These may be provided by the ground handler, the airport or the airline operator and should be designed to be compatible with the aircraft type, and to provide adequate protection from risk of falls. What is the condition of the Slide Arming Lever when the yellow arm plate is down and flush with the door?

This is why when you are cruising in an airliner, it is usually bright and sunny, with all the cloud and rain below you. 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. 35 to 60 minutes, depending on the fuel pressure. More specifically, they are smaller than 25 inches. Where are the Live TV circuit breakers located? If the exit is located over the wing, the step-down outside the airplane may not exceed 27 inches. 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. FUEL RECEPTACLE GROUND HEIGHT It all makes sense when you know the reasons for it! 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. It is probably not really safe for them to be much above 10,000 feet. 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. Which SSR code describes my disability assistance needs? [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. 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. 3) the work that is being done, for instance whether it involves handling awkward or heavy loads, the suitability of platform or step design. When on Battery Power, which Dome light can be turned on? 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. In some emergencies, such as a rapid decompression, pilots want to return to a lower altitude as quickly as possibe. 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. Airline personnel can assist you with this, if you bring the tools (typically a small wrench to loosen bolts) with you.

Let us know your thoughts and experiences in the comments. Further guidance is also contained in various British and European standards on which the Transportation Section can advise. Which color illuminates in a switch to inform the crew that a system is available? Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft This is not a factor in commercial flying. 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. An airplane altimeter is a gauge that indicates the height of the plane above the ground. [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 aircraft is equipped with ____ cabin doors. All a snowbound skier had to cat were walnuts! Independent of the inflation system, all slides are equipped with at least one pressure relief device per inflation chamber. The 787-8 is equipped with eight passenger entry Aircraft painted in beautiful and original liveries, Airport Overviews These include the Boeing 767, Boeing 757, and Airbus A320-series aircraft. Flying higher means that commercial airplanes can avoid most other airborne traffic. This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. Also, most small planes are not equipped with oxygen, which would be necessary if they were to fly too high. Cargo holds vary in size, based on the aircraft type. He was carrying a bag holding 12 dozen nuts. To avoid rapid depressurization, it is paramount that these structures cannot be breached inflight. How to request wheelchair assistance at the airport?

With his mittened hands, he cracked open the shells. Wiki User 2010-05-04 18:35:56 Study now See answer (1) Copy Depending on Aircraft Gross weight and strut. This damage can be classified as follows: 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. 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. This may, for example, involve lifting up the flap on the girt bar, and pulling the detach handle. A device can be used to prevent this problem. If not. As the operation and design of such steps are part of the aircraft design, safe operation is dependent on training and competence of cabin crew. Why didn't they make the 757 wider. These procedures are usually placarded red on the slide, "For Ditching Use Only". 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. 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. Tests in 25-knot (46km/h) cross winds have shown these deployment systems to be very effective. In many modern planes, to reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. Both military and civil versions, Blimps / Airships 17 Where doors are opened from outside by ground handlers such as caterers, the guidance in SIM 05/2008/02 applies. Birds rarely fly that high, which is important, as bird strikes, though rare, can be disastrous if they happen. A bit out of topic, but since the 757 and 737 have the same fuselage width, do they share any similar parts? The minimum for these large jets would sit around . Helps a lot. The plane set to take off for Puerto Rico struck the tail of another JetBlue plane with no one inside. Aircraft painted in beautiful and original liveries, Airport Overviews These may be attached to the inside frame of the window exit, or located in a nearby storage locker. [6], There are four types of inflatable aircraft evacuation aid covered by EASA Technical Order:[7]. 35,000 feet or thereabouts is the altitude at which fuel efficiency is greatest, while there is still enough oxygen available to power the engines. What is the height from the ground to the bottom of the cargo door on a KC-135? 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). 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. Passing through an aircraft door represents the start or end of one's time onboard an aircraft. 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.

The new slide/raft design was put forward to the International Air Transport Association (IATA), by Jack Grant, Qantas operations safety superintendent. The main reason for airliners flying so high is that it saves fuel and therefore saves money, which is always a priority for airlines. 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. Electrical anti-ice is operated for all flight operations to inhibit ice build up. So again, there has to be a balance, which accounts for the altitudes generally used. How aircraft doors open can differ, but the first movement is always one of inward motion. 24 The Turnround Plan should ensure that all ground staff have completed their tasks and left the aircraft or can exit safely using passenger steps before doors are closed and steps removed. 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. All large commercial aircraft have escape slides on the main doors but some also have slides for exits over the wings. What can we see in terms of the general dimensions of Y1, in this respect? Approximately how high is the bottom of the cabin door from the ground? During transit or during maintenance visits, the aircraft doors may need to remain open for a number of reasons. After this, some will swing to the side, whereas others retract towards or even into the aircraft's ceiling. An open door displays in _____. 42 The Work at Height Regulations 2005 address all work at height where a person could fall a distance liable to cause personal injury. 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. Check these cargo hold dimensions! 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. Movement of the _______ are a computerized response to a side stick or autopilot request. according to Boeing manual, the front passenger door: min. Batteries that appear to be damaged or leaking may be removed and separately packaged by the carrier. Journalist - A graduate in German, Jake has a passion for aviation history, and enjoys sampling new carriers and aircraft even if doing so demands an unorthodox itinerary. Potable Water pressure is provided by _________. 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. And a substantial majority of small planes are flown for recreational purposes, and pilots enjoy flying lower, where they can see things below them. Each nut that was opened resulted in one kernel and two shell halves. Gravity will then pull the slide to the ground and it will inflate. This may mean modifying the equipment or using fall restraint equipment in the short term. Can I use my own wheelchair in the airport? Did you know how aircraft doors worked? What is so special about the outboard arm rest on each pilot seat? Boeing airplanes is shown in figure 7. The 777F accommodates 27 standard pallets (96 by 125 inches; 2.5 by 3.1 meters) on the main deck. Accident, incident and crash related photos, Air to Air 29 These doors should only be used for emergency evacuation. This is one way in which they are kept secure despite the strong forces that aircraft encounter inflight. During test flights this maximum is exceeded slightly to verify the that airplane remains safe should it have cause to ascend from that limit. For the slide to deploy correctly, it is packed in a manner that has the aspirators directly under the outer cover. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft Any reason why? 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. 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. One end has a buckle to connect to attachments on the aircraft's wings. 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 What is the reason for the low ride height of the 737, as I think it limits the length the fuselage can be stretched? Training should include aircraft manufacturers requirements, awareness of emergency chute operation and deactivation and risk of falls. 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. Prior to departure (usually before engine startup), all the aircraft doors are placed into the armed (or automatic) mode by the cabin crew. At wide doors typical on large aircraft these will be "dual lane" slides capable of carrying two parallel lines of evacuees. 10 Some airlines have already introduced door nets to protect against falls from open doors. Representatives of airlines, airports and ground handlers have worked with HSE in the development of this guidance. Any standard fuel truck (i.e., hydrant/tanker) 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. Assuming radial entry flow, determine the theoretical values for (a) the flow rate and (b) the power. Powered wheelchairs andscooters almost always have to be stored underneath the airplane in the cargo hold. Whilst bigger than the Embraer E-Jets, Boeing feels this is an optimum size range for a small city jet which can also be used for medium-haul international services. Views from inside the cockpit, Aircraft Cabins Anchorages need to be proof tested when installed and when any usage changes. 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. Delta Air Lines' departing Boeing 737 plane then came to a safe stop on the John F. Kennedy International Airport runway as the other crossed in front around 8:45 p.m., the Federal Aviation . Such nets or restraint systems must be adequately tested and secured. One of the newest developments in evacuation slide technology can be found on the Airbus A380, which was developed by Goodrich Aircraft Interior Products. 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. 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. Aircraft flying government officials, Helicopters
