23 Clear procedures and means of communication should also be in place for removal of aircraft steps. What are the names of the control laws that are used to operate the flight controls? Previously life rafts were carried separately in the cabin and deployed manually by the crew after a water landing. A centrifugal pump has the following dimensions: d2 = 42 cm, L = 5 cm, and $\beta 2=33^{\circ}$. The aircraft is equipped with ____ cabin doors. 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. Thanks guys. That's quite high due to the 747 cockpit location on the upper deck. The CO2 is used to slow down the rate at which the valve expends the gases. 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. 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. 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). Older slides are yellow and made of neoprene/nylon fabric. (379 kilopascal). Aircraft Cargo Door Opening/Sill Details for Ground Support Equipment Interface AIR1673B . Engine anti-ice is supplied to the _______. If the exit is located over the wing, the step-down outside the airplane may not exceed 27 inches. 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. Particularly a SunCountry 737-800 ? 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. 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. 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 also minimizes the risk of accidental opening. Independent of the inflation system, all slides are equipped with at least one pressure relief device per inflation chamber. Both slides and slide/rafts use non-explosive, inert gas inflation systems. As soon as a plane lands and clears the active runway, the pilots receive taxi instructions from ground controllers. However, such doors do sometimes find themselves unintentionally open. Instead the precautions will be identified solely on the basis of an assessment of the risks involved. 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 large helicopter section. Offering customers one of the most spacious interiors of all single-aisle aircraft, it also delivers impressive economics. At wide doors typical on large aircraft these will be "dual lane" slides capable of carrying two parallel lines of evacuees. HSE aims to reduce work-related death, injury and ill health. 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. 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. They are usually about the same width and height as a seat. 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. 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). There are also half-tie restraints which keep the inflating slide from drooping or blowing under the aircraft. In some emergencies, such as a rapid decompression, pilots want to return to a lower altitude as quickly as possibe. Aircraft General DIMENSIONS Width : 35.79 m Lenght : 39.5 m . 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. a fueling panel with two receptacles, each rated Aircraft doors are designed to be used on the ground, where they are not subjected to the pressure difference found at altitude. Powered wheelchairs andscooters almost always have to be stored underneath the airplane in the cargo hold. Helps a lot. 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. Aircraft ground equipment Passenger boarding bridge or transfer vehicle Requirements for interface with aircraft doors. Depending on the size of your wheelchair/scooter, you may need to fold down your seatback in order for it to fit into the hold. This is a major inconvenience, as it can disrupt your travel plans.

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. In 1965 the idea was further developed by combining the inflatable slide with an integrated raft. The Management Regulations also set out requirements for co-operation and co-ordination between employers. Aircraft doors refer to passenger doors, cargo doors and ground service access doors to various areas of the fuselage. Accident, incident and crash related photos, Air to Air by users, inspections by competent persons, as well as any statutory inspections required by Lifting Operations and Lifting Equipment Regulations (LOLER). a. 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. Noah's ark of the skies: Big or small, domesticated or not, Cargolux has solid expertise in transporting live animals across the world. The main reason for airliners flying so high is that it saves fuel and therefore saves money, which is always a priority for airlines. Where is the control switch for the Standby Compass Light? If not. They rarely ask about it, or want to know what altitude is used. 16 Open aircraft doors must be protected by effective fall prevention barriers, ground support equipment or other means. 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. 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. What is the normal configuration for switches and lights on the A320? [11], Inadvertent slide deployment occurs when the operator of the aircraft door attempts to open the door when it is in the armed position. It represents the fusion of performance and technology, allowing airlines to connect distant points on continents and for route sectors that were previously unprofitable or impossible to perform. Air pressure is measured in kilopascals (kPa). Movement of the _______ are a computerized response to a side stick or autopilot request. To meet this, all evacuation units need to deploy in less than 10 seconds. It should be noted that every airplane has a certified maximum altitude. A dramatic video shot on a smartphone from the ground shows the last moments before the plane crashed in a gorge about 1.6 kilometers (a mile) from newly opened Pokhara International Airport. 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. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft On the other hand, flying too high could have negative safety issues. AIRCRAFT MODEL: WINGSPAN: . An airplane altimeter is a gauge that indicates the height of the plane above the ground. While HSE is aiming for maximum protection for ground workers at airports, the airlines responsibility for cabin crew must also be considered, with consistent procedures to facilitate training. 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. What is the height from the ground to the bottom of the cargo door on a KC-135? It is the responsibility of those involved in both organisations to liaise where they believe there may be a joint interest or need for clarification of responsibilities to ensure that such matters are dealt with effectively, and to ensure there is no conflict of responsibilities with the other organisation. This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. 29 These doors should only be used for emergency evacuation. 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. A bit out of topic, but since the 757 and 737 have the same fuselage width, do they share any similar parts? Aircraft safety cards and in-flight safety demonstrations show the passengers where the nearest emergency exits are and how to use the evacuation slides. [9] Certain slides on board the aircraft have the Tribrid Inflation System, which is connected to a sensing system within the door. Assuming a 3,730-U.S. gallon (14,120-liter) CV jumbo 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. Doors should never be left unprotected once open. According to Quora user and aircraft maintenance engineer Jan Krusat, the makeup of the 767's design team played a key role. 's laboratory values. 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. Type I Slides and Type II Slide/Rafts both function the same on land allowing descent from the door to the ground. Which SSR code describes my disability assistance needs? reach the 787-8 receptacles can be used. Therefore small planes generally fly between 2000 and 10,000 feet. What is the reason for the low ride height of the 737, as I think it limits the length the fuselage can be stretched? Planes flying eastward, including northeast and southeast, will fly at odd altitudes, such as 35,000 feet. 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. Sodium 138 mEq/L \ Lastly, flying high gives you more time to act in the unlikely event of an emergency in flight. Most of the time, flight attendants seamlessly operate these structures.

Electrical anti-ice is operated for all flight operations to inhibit ice build up. 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. More specifically, they are smaller than 25 inches. 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. 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. So again, there has to be a balance, which accounts for the altitudes generally used. 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. 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. Fuel Receptacle 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. [6], There are four types of inflatable aircraft evacuation aid covered by EASA Technical Order:[7]. This protects the chamber from catastrophic failure due to over pressurizing. stairs and bridges are common with 767 and 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. Every type from fighters to helicopters from air forces around the globe, Classic Airliners Airport overviews from the air or ground, Tails and Winglets These types of aircraft have a door sill height greater than 2,0 m (80 in) above the ground. reserve, the 787-8 can be refueled to capacity in Love the way they look though!!!!!!!!
