Interpret F.N. 32 Attachment points must be of sufficient strength to support the load imposed by the weight of the worker in the event of a slip or trip and should be fitted and tested by a competent person. 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. This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. 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. Whereas, I think the 737 looks very short and squatty. A fueling control panel 16 Open aircraft doors must be protected by effective fall prevention barriers, ground support equipment or other means. 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. doors four on each side of the airplane The cylinder's volume can be between 100 and 1,000 cubic inches (1.6 and 16.4 litres), pressurized to about 3,000 pounds per square inch (200 standard atmospheres) with either gaseous Nitrogen (N2), or a mixture of Carbon Dioxide (CO2) and Nitrogen. We have established the mechanical means by which aircraft doors are kept shut, but there is another aspect to consider. [13] On the primary entrance door, 1L, some of these aircraft have stairs that are either connected to the door or drop down. This is all in addition to any maintenance that is specified by the manufacturer. 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. The next widebody, DC-10 can be found at Short hops or longer routes - the E190 has the versatility to go the distance. A device can be used to prevent this problem. They should also have sufficient authority to take any necessary action if a situation of imminent danger is identified. 12 Some aircraft doors are automated or semi-automated which can reduce the risks of approaching an unguarded edge to open or close the door. (379 kilopascal). When the slide is in the armed position and the door is opened, the slide pack falls free of the door bustle (a semi-rigid outer container) and the weight and momentum of the slide pulls the lanyard from the valve, initiating the flow of gas. 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.

It is proposed that catering of the new Airbus A380 can be carried out via upper deck doors. 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. A bit out of topic, but since the 757 and 737 have the same fuselage width, do they share any similar parts? 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. Both MUST be fully conversant with the signals or codes to be used. Lastly, flying high gives you more time to act in the unlikely event of an emergency in flight. [11], Inadvertent slide deployment occurs when the operator of the aircraft door attempts to open the door when it is in the armed position. 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. To meet this, all evacuation units need to deploy in less than 10 seconds. The CO2 is used to slow down the rate at which the valve expends the gases. 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. Views from inside the cockpit, Aircraft Cabins [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 777F accommodates 27 standard pallets (96 by 125 inches; 2.5 by 3.1 meters) on the main deck. 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. When activated, how long should the Emergency Lights last? 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. 60 Given the potential for injury it is essential that a suitable and sufficient risk assessment is carried out. They rarely ask about it, or want to know what altitude is used. Representatives of airlines, airports and ground handlers have worked with HSE in the development of this guidance. (Maximum 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. (4) Type IV. Where is the control switch for the Standby Compass Light? 17 Where doors are opened from outside by ground handlers such as caterers, the guidance in SIM 05/2008/02 applies.
