In many modern planes, to reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. Where are the Live TV circuit breakers located? This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. (Maximum Both slides and slide/rafts use non-explosive, inert gas inflation systems. This sort of thing is extremely unlikely, but it does happen occasionally. Pictures of great freighter aircraft, Government Aircraft 35 to 60 minutes, depending on the fuel pressure. Typically there are two high pressure hoses attached to the valve, which are connected at the other end to aspirators. Any reason why? 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. reserve, the 787-8 can be refueled to capacity in Most airline passengers simply accept the fact that passenger jets fly very high. It is proposed that catering of the new Airbus A380 can be carried out via upper deck doors. However, it is important to note that this only tends to be the case on passenger 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. Typically, this will involve providing guarded access equipment and fall protection equipment. Door opening may be from inside or outside the aircraft but must be according to agreed procedures, to avoid any risk of accidental activation of the emergency chute. 64 The industry has worked with HSE on this issue and there is general industry acceptance that the standards outlined in this document are reasonably practicable. 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. Typically, aircraft fly around 35,000 or 36,000 feet above sea level. Beautiful shots taken while the sun is below the horizon, Accidents . Helps a lot. Who makes the plaid blue coat Jesse stone wears in Sea Change. Also, most small planes are not equipped with oxygen, which would be necessary if they were to fly too high. Can I check my wheelchair at the boarding gate? Some switches illuminate a ____ light when they are selected ON, to advise the crew that they are selected on and operating. Today some of the corporate jets can fly at 51,000 feet. Views from inside the cockpit, Aircraft Cabins 777 airplanes. From Boeing's data, a 747-8 cockpit ranges from 7.56 to 7.90m above the ground . 9 Airlines have the ultimate responsibility for procedures for opening their aircraft doors. Passing through an aircraft door represents the start or end of one's time onboard an aircraft. Aircraft painted in beautiful and original liveries, Airport Overviews It is not essential for aircraft to avoid bad weather, but it is a good idea. 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. 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. The total fuel capacity for the 787-8 is 33,528 U.S. What is the $K_{\text {eq }}$ for this reaction? 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. 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. 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). Birds rarely fly that high, which is important, as bird strikes, though rare, can be disastrous if they happen. Specific requirements for different types of GSE are in BS EN 12312 (see Appendix 1 ). 29 These doors should only be used for emergency evacuation. These types of aircraft have a door sill height greater than 2,0 m (80 in) above the ground. The Boeing 737 is designed to fill the smaller jet airliners space over a given range of seats. 14 Signals in use for door opening procedures vary at UK airports and between aircraft operators. Cabin Door Safety Strap 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. 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. I hope this has not already been discussed. Let us know your thoughts and experiences in the comments. We thank you for your support and hope you'll join the largest aviation community on the web. 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. 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. Aircraft doors are designed to be used on the ground, where they are not subjected to the pressure difference found at altitude. 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. The failure to undertake a risk assessment should be dealt with by reference to the EMM. It is probably not really safe for them to be much above 10,000 feet. Sets found in the same folder A320/321 Oxygen But there are good reasons for how high planes fly. Both military and civil versions, Blimps / Airships CHENNAI/NEW DELHI/BENGALURU: An emergency exit of an Indigo flight was accidentally unlocked by a passenger last month while the aircraft was on the ground, delaying it for over two hours. How aircraft doors open can differ, but the first movement is always one of inward motion. 34 Employees involved in airside operations must receive specific training on airside safety awareness, vehicle and aircraft familiarisation, aircraft approach and full use of safety features and procedures, including relevant turnaround plans, whilst servicing aircraft. 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. Canvas type slides are still found on some out of production Russian aircraft. 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 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. 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 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. 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. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft 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. with the appropriate length fuel line that can Specifically, several members of this group were former McDonnell Douglas engineers. Again, airliners can generally cope with turbulence, but it is preferable to avoid it if possible. Communication is again paramount. nose up position due to the loss of landing gear), the slide will inflate normally but will also inflate several feet of additional slide to ensure the slide reaches the ground. Cargo holds vary in size, based on the aircraft type. 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. 17 Where doors are opened from outside by ground handlers such as caterers, the guidance in SIM 05/2008/02 applies. 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. All a snowbound skier had to cat were walnuts! a. How can I reduce the risk of my wheelchair being damaged? Both military and civil versions, Blimps / Airships Anyway, I was curious about the ground height of the 757 in relation to the 737. -N60659 RE: Question About 737 Door Height From Ground #4427985 This is why when you are on a long flight, you will . Our large helicopter section. Which display unit shows the Engine/Warning Display (E/WD)? Where immediate prohibition could cause significant health and safety or air safety risks, a deferred notice should be considered. Various forms of indicators, such as lights, flags and pins with ribbons are used to indicate an armed condition.[10]. 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. There are certain rules for exactly where airliners can fly, and the direction of travel can affect what altitude they will climb to. What is the reason for the low ride height of the 737, as I think it limits the length the fuselage can be stretched? . 62 The long term aim should be better designed access equipment, better guarding, and improved design of aircraft doors and their opening mechanisms. It rotates at 1200 rpm, and the head generated is 52 m of water. That's quite high due to the 747 cockpit location on the upper deck. (379 kilopascal). In such cases, safety equipment must be used and certain precautions followed. What is the height from the ground to the bottom of the cargo door on a KC-135? Some Russian-built aircraft like the Tupolev Tu-154 have a very complicated process to activate and deploy the slides. To meet this, all evacuation units need to deploy in less than 10 seconds. [13] On the primary entrance door, 1L, some of these aircraft have stairs that are either connected to the door or drop down. This may mean modifying the equipment or using fall restraint equipment in the short term. Another unique type of evacuation slide is found on the DC-9 family of aircraft and its successors the MD-80 and Boeing 717. How many video display units are installed in the cockpit? 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. Interpret F.N. 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. After this, some will swing to the side, whereas others retract towards or even into the aircraft's ceiling. There are a number of Annexes to the MoU on specific areas. Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes In 1965 the idea was further developed by combining the inflatable slide with an integrated raft. And a substantial majority of small planes are flown for recreational purposes, and pilots enjoy flying lower, where they can see things below them. This protects the chamber from catastrophic failure due to over pressurizing. Glucose 202 mg/dL \ However, a planes engines need oxygen in order to function, so flying too high can also cause problems. The aircraft was on the ground at the time of the incident. 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. [11], Inadvertent slide deployment occurs when the operator of the aircraft door attempts to open the door when it is in the armed position. Clear procedures and signals should be used to open the door. Technical Specifications Dimensions Wing Area: 5,500 ft2 (510.95 m2) Exterior Exterior Height: 63 ft 5 in Wing Span: 195 ft 8 in Length: 231 ft 10 in Interior Cabin Width: 20 ft 0 In Internal Baggage: 6,190 cu ft Occupancy Crew: 3 Passengers: 539 Operating Weights Max T/O Weight: 735000 Lb Fuel Capacity: 48445 gal Lb Range Max Range: 5292 nm Everything from the Goodyear blimp to the Zeppelin, Night Photos 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. by users, inspections by competent persons, as well as any statutory inspections required by Lifting Operations and Lifting Equipment Regulations (LOLER). [6], There are four types of inflatable aircraft evacuation aid covered by EASA Technical Order:[7]. Can the aircraft be flown with the Cabin Surveillance System (CSS) inoperative? Views from inside the cockpit, Aircraft Cabins Everything from the Goodyear blimp to the Zeppelin, Night Photos 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. Doors Dimensions: Main Entry Door (front right): 34 by 72 inches At the end of the walkway is the slide pack and a manual tailcone jettison handle for use if the tailcone has not already been automatically jettisoned by opening the walkway entrance. Fuel receptacle ground height for the 787-8 and other Boeing airplanes is shown in figure 7. Slides are required on all passenger carrying aircraft where the door sill height (measured as the normal height above ground level) is such that able bodied passengers would be unable to jump or "step down" from the exit without a significant risk of injury. Our site uses cookies. 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. Most of the time, flight attendants seamlessly operate these structures. In the center, forward part of the pack, a multi-layered piece of heavy urethane or neoprene/nylon fabric, called the girt, is left hanging out to a length of about 2ft (0.61m). The troposphere is usually said to finish at 36,000 feet. 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.
