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. Both military and civil versions, Blimps / Airships The practice of differentiating between the precautions required for high falls and low falls will no longer apply. . Also, new units are usually constructed of urethane materials and impregnated or coated with an aluminized coating so that the slide will survive for a short while even if fire is nearby. This is not a factor in commercial flying. stairs and bridges are common with 767 and A groundbreaking concept in the air. Wind will determine how fast the aircraft is travelling across the ground on touchdown and how long it will need to brake thereafter. 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. [1] To reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. Indeed, they often fly much lower than this. 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. It rotates at 1200 rpm, and the head generated is 52 m of water. 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. 6). 39 Doors should only be opened by door trained personnel. Other means of access includes service vehicles such as catering high loaders. 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. 62 The long term aim should be better designed access equipment, better guarding, and improved design of aircraft doors and their opening mechanisms. There are also half-tie restraints which keep the inflating slide from drooping or blowing under the aircraft. Particularly a SunCountry 737-800 ? 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. for 500 U.S. gallons per minute (1,893 liters per In particular aircraft structures and components are subject to stringent design requirements, and attachment points can only be provided according to manufacturer's specifications and approval. What can we see in terms of the general dimensions of Y1, in this respect? Their suggestions involved planning, exiting the aircraft and getting off the slide quickly, jumping, the correct body position and avoidance of clothing that could cause safety issues, such as spiked heels and pantyhose. Aircraft painted in beautiful and original liveries, Airport Overviews Contravention of the ANO or any Regulations made under it is a criminal offence. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft 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. Previously life rafts were carried separately in the cabin and deployed manually by the crew after a water landing. 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. It also emphasises the importance of communication between cabin crew and ground staff and use of standard signals (thumb-up signal and knocking at the door). with the appropriate length fuel line that can There are a number of Annexes to the MoU on specific areas. (4) Type IV. 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. Parking the plane. However, it is important to note that this only tends to be the case on passenger aircraft. Copyright 2023 Pilot Institute. RE: 737 And 757 Ground Height #4708763 BY phollingsworth - Thu Feb 09, 2006 5:44 am Taking the FWD entry door sill height as an example. 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. A keen amateur photographer, he also recently reached the milestone of flying his 100th sector as a passenger. 9 Airlines have the ultimate responsibility for procedures for opening their aircraft doors. 11 There are 3 main types of aircraft door: 1) Passenger cabin access doors These doors are used for: Passenger access and egress Servicing the aircraft eg catering 2) Overwing (emergency. If the exit is located over the wing, the step-down outside the airplane may not exceed 27 inches. 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. 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. Which color illuminates in a switch to inform the crew that a system is available? It can be installed as a stand-alone unit or integrated into the aircraft systems and powered from aircraft power. Gravity will then pull the slide to the ground and it will inflate. Slides fitted by main fuselage doors are mounted on the door itself. Typically, aircraft fly around 35,000 or 36,000 feet above sea level. It also minimizes the risk of accidental opening. Air pressure is measured in kilopascals (kPa). Cabin Height: 7 ft 4 In Cabin Width: 12 ft 2 In Cabin Length: 90 ft 2 In Cabin Volume: 6,825 cu ft Door Height: 6 ft 1 In Door Width: 2 ft 8 In Internal Baggage: 128 cu ft Occupancy Crew: 3 Passengers: 19 Operating Weights Max T/O Weight: 169785 Lb Max Landing Weight: 145505 Lb Operating Weight: 97653 Lb Empty Weight: 82078 Lb Specifically, several members of this group were former McDonnell Douglas engineers. On older aircraft, such as the Boeing 737, this is done physically by the cabin crew and on most other aircraft it involves pushing a lever on the door itself which arms the door internally. The highest certified altitude of an airliner was Concordes 60,000 feet. Type I Slides and Type II Slide/Rafts both function the same on land allowing descent from the door to the ground. Steps or a platform must be in position outside the door before it is opened to provide protection from falling, and guard rails must be fully positioned as soon as the door is open. Cabin Door Safety Strap Did you know how aircraft doors worked? Planes flying eastward, including northeast and southeast, will fly at odd altitudes, such as 35,000 feet. 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. These types of aircraft have a door sill height greater than 2,0 m (80 in) above the ground. Once made of steel, most cylinders now are made of aluminum or alloy cores wrapped with fiberglass, or other lightweight, fuel saving materials. Which SSR code describes my disability assistance needs? Movement of the _______ are a computerized response to a side stick or autopilot request. This is one way in which they are kept secure despite the strong forces that aircraft encounter inflight. Carriers may require that passengers wishing to have battery powered wheelchairs transported on a flight check-in one hour prior to scheduled departure. 48 Specific guidance on the roles and responsibilities of those involved in aircraft turnround is given in Aircraft Turnround HSG209. 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). Regardless of the position of the EMER light sw in the flight deck, the F/A sw can activate the Emergency Lights. A teacher walks into the Classroom and says If only Yesterday was Tomorrow Today would have been a Saturday Which Day did the Teacher make this Statement? The main reason for airliners flying so high is that it saves fuel and therefore saves money, which is always a priority for airlines. The following conditions are outlined by the ACAA regarding the carriage of a power wheelchair or scooter: If you arent sure how to disassemble your wheelchair, contact your local wheelchair supplier or reach out to the manufacturer. Fuel receptacle ground height for the 787-8 and other Boeing airplanes is shown in figure 7. Approximately how high is the bottom of the cabin door from the ground? This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. A farmer has 19 sheep All but 7 die How many are left? On the other hand, flying too high could have negative safety issues. As far as possible signals and procedures should be standardised to avoid confusion for cabin or ground crew. FUEL RECEPTACLE GROUND HEIGHT What is the reason for the low ride height of the 737, as I think it limits the length the fuselage can be stretched? [1] There are also design requirements for passengers to be able to evacuate within certain limits; typically 90 seconds for large aircraft. The left wing has Heads up this was for Grand Forks Flight Support who will be handeling a SunCountry 737-800 charter for UND Fighting sioux football tomorrow. 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. This is why when you are cruising in an airliner, it is usually bright and sunny, with all the cloud and rain below you. We are looking for clear, consistent procedures, signals and communication which can be applied at all airports for each aircraft type, as far as this is possible. 3) the work that is being done, for instance whether it involves handling awkward or heavy loads, the suitability of platform or step design. I did a search, but returned nothing. (Typically, modern slides are made of at least two inflation chambers, and should be able to evacuate an aircraft even when one chamber loses all pressure.). 19 Where an air bridge is used the risk of a fall is minimised. Such nets or restraint systems must be adequately tested and secured. It works as an independent system, requiring no action other than arming the door as per normal standard operating procedures. 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 Modern airliners are incredibly safe most of the time, but should something happen which means an emergency landing is required, high altitude gives the pilots much longer to sort things out and find a safe place to land. Where doors are open and passengers are on board the aircraft it is particularly important that the doors are guarded either by a physical barrier or by a suitably trained crew member. 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. Boeing airplanes is shown in figure 7. This should be considered as a strategic factor for the purposes of the EMM. Today some of the corporate jets can fly at 51,000 feet. 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. However, other versions of the story claimed that a passenger had accidentally opened it from the inside. 35 to 60 minutes, depending on the fuel pressure. Assuming a 3,730-U.S. gallon (14,120-liter) 16 Open aircraft doors must be protected by effective fall prevention barriers, ground support equipment or other means. Typically, this will involve providing guarded access equipment and fall protection equipment. 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. Any reason why? They work on the Venturi principle, and draw outside air into the evacuation unit at a rate of about 500:1. What happens if an airline damages my wheelchair? 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. Potassium 2.Smmol/L \ 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. The reasons behind the quirk. In many modern planes, to reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. Where is the control switch for the Standby Compass Light? two cargo doors on the right side, and one bulk 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. Learn more about our use of cookies in our, Unisex President Franklin D. Roosevelt T-Shirt (Multiple Colors), Unisex Equal Access Everywhere T-Shirt (Multiple Colors), Wheelchair Must Be Loaded Upright Keychain/Baggage Tag, how to prevent damage to power wheelchairs on airplanes. 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. These procedures are usually placarded red on the slide, "For Ditching Use Only". After this, some will swing to the side, whereas others retract towards or even into the aircraft's ceiling. When the cover is released and the inflation system activated, the two aspirators come shooting out of the pack, gulping vast quantities of air and restrained only by the fabric tubes to which they are securely fastened. Whereas, I think the 737 looks very short and squatty. We thank you for your support and hope you'll join the largest aviation community on the web. Both slides and slide/rafts use non-explosive, inert gas inflation systems. 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 . Anchorages need to be proof tested when installed and when any usage changes. Procedures may also include a count down before opening the door. Note that powered wheelchairs with a reclining seatback often require much more significant disassembly. Cargo Door (LH) Clear Opening Width: 134 in (3.4 m) Height: 103 in (2.6 m) Forward Lower Deck Cargo Door Clear Door Opening Width: 134 in (above rollers)(3.4 m) Height: 69 in (1.7 m) Aft Lower Deck Cargo Door Clear Door Opening Width: 70 in (above rollers)(1.7 m) Height: 69 in (1.7 m) (24) 88 in x 125 in x 96 in Longitudinal Pallets/Containers Our large helicopter section. Airliners.net is the leading community for discovering and sharing high-quality aviation photography. 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. Door status is indicated on the ECAM DOOR page. 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. 57 The risk of a fall will depend on various factors including: 1) procedures in place for opening aircraft doors. So again, there has to be a balance, which accounts for the altitudes generally used. Passing through an aircraft door represents the start or end of one's time onboard an aircraft. Escape slides are packed and held within the door structure inside the slide bustle, a protruding part of the inside of an aircraft door that varies with aircraft size, door size and door location. 61 Where inspectors find failings of management systems such as: 1) absence of suitable risk assessments; and/or, 2) inadequate arrangements for planning, organising, control etc; and/or, 4) employees are not following safe practices while opening/ closing aircraft doors; and/or, 5) there is a lack of suitably guarded access equipment; and/or. Where immediate prohibition could cause significant health and safety or air safety risks, a deferred notice should be considered. 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. Use of the aircraft attachment points may be used as a means of averting damage to the aircraft door frames and other important parts. All a snowbound skier had to cat were walnuts! 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. To compensate for any wind, new evacuation slides contain internal baffles, which cause the ends nearest the aircraft to inflate first, which are constructed to come out like four elbows and press against the fuselage of the aircraft to the forward and aft sides of the exit door. At wide doors typical on large aircraft these will be "dual lane" slides capable of carrying two parallel lines of evacuees. How to request wheelchair assistance at the airport? 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. 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). NOTE: All passenger cabin doors may be used for emergency evacuation, Cargo and hold doors are not included in this guidance. 37 Supervisors with a responsibility for ensuring that the workplace is safe must be able to recognise any inadequacies in equipment or work practices and will therefore need suitable training. During test flights this maximum is exceeded slightly to verify the that airplane remains safe should it have cause to ascend from that limit. The Fuel Quantity Display is located on the ________. This may mean modifying the equipment or using fall restraint equipment in the short term. Posted on August 27, 2021 - 5 minute read. It should be noted that every airplane has a certified maximum altitude. Employees using fall protection equipment should be trained in its safe use, including user equipment checks. Beautiful shots taken while the sun is below the horizon, Accidents Waste tank negative pressure is provided by cabin differential air when the aircraft is above ______. 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. 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. This is for guidance only; any enforcement should be determined by the circumstances found on site. Any standard fuel truck (i.e., hydrant/tanker) Slides can be single or dual lane, depending on the width of the exit they are fitted to and in testing must show a nominal exit rate of 70 people per minute per lane. But there are good reasons for how high planes fly. 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. Aircraft doors are designed to be used on the ground, where they are not subjected to the pressure difference found at altitude. I'm surprised to see the door height of the 732 even lower than that of the 733/4! Let us know your thoughts and experiences in the comments. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft 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. Therefore small planes generally fly between 2000 and 10,000 feet. Chloride 103 mEq/L \ The Boeing spec sheet lists 9'-00" at OEW and 8'-06" at MTW for a B738. Where possible the door should be closed before the steps are moved away from the aircraft. Last month, a DHL Boeing 757's cargo door opened inflight in Germany, although, thankfully, the aircraft was able to land safely and without injuries to its crew. Can I check my wheelchair at the boarding gate? 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. The total fuel capacity for the 787-8 is 33,528 U.S. The aircraft had a takeoff weight of 892,450 pounds (404,810 kg), and in order to satisfy Fdration Aronautique Internationale regulations, climbed to a height of 6,562 feet (2,000 m). 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. To be suitable the assessment should consider the issues identified above. Both MUST be fully conversant with the signals or codes to be used. Canvas type slides are still found on some out of production Russian aircraft. 17 Where doors are opened from outside by ground handlers such as caterers, the guidance in SIM 05/2008/02 applies. 14 Signals in use for door opening procedures vary at UK airports and between aircraft operators. 31 There are considerable limitations on the use and suitability of fall protection or work restraint equipment on aircraft and access platforms, including availability of attachment points that are rated for fall arrest (ie strong enough), actual height of work, whether there is sufficient height for a fall arrest system to work, the risk of hitting obstructions on the aircraft or vehicle during a fall, and the additional safety risks introduced in attaching and using harnesses. If carried out externally there may be impact from the weather conditions such as high winds. book answer is 10 feet. a. Every type from fighters to helicopters from air forces around the globe, Classic Airliners All Rights Reserved. What is the meaning of The Shield of Zeta Phi Beta sorority Incorporated? 2 Risks arise during maintenance of aircraft and during servicing and turnaround activities. Commercial airplanes can theoretically fly a little higher than this, and of course they can also fly lower if they choose to. Airline personnel can assist you with this, if you bring the tools (typically a small wrench to loosen bolts) with you. These include the Boeing 767, Boeing 757, and Airbus A320-series aircraft. The failure to undertake a risk assessment should be dealt with by reference to the EMM. Another unique type of evacuation slide is found on the DC-9 family of aircraft and its successors the MD-80 and Boeing 717. Type IV combines the ramp and slide into a single functional unit. 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. 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. Because of the accidental emergency slide deployment that followed, the flight ended up being delayed for seven hours. Ground Height). Well the low ones are a lot easier to load without. During transit or during maintenance visits, the aircraft doors may need to remain open for a number of reasons. 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. Glucose 202 mg/dL \ AIRCRAFT MODEL: WINGSPAN: .
