Plus if a plane goes higher, it has to burn more fuel in order to get there. 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. To avoid rapid depressurization, it is paramount that these structures cannot be breached inflight. 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. 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. A groundbreaking concept in the air. Data not published, based on our estimates, center aisle. Both military and civil versions, Blimps / Airships Chloride 103 mEq/L \ 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. Tests in 25-knot (46km/h) cross winds have shown these deployment systems to be very effective. 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. Door status is indicated on the ECAM DOOR page. Where current equipment and guarding are obviously inadequate, we should be asking for immediate improvements. But in fact, small aircraft generally fly much lower than that for a variety of other reasons. Indeed, a similar situation befell another PIA aircraft in 2019. When activated, how long should the Emergency Lights last? 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. 21 Whether the door is opened from inside or outside, the steps and adjustable guard rails should be positioned as close to the aircraft as possible to avoid risks of falls from the platform or the open door. Procedures may also include a count down before opening the door. This is why when you are on a long flight, you will . Most airline passengers simply accept the fact that passenger jets fly very high. The regulating valve mechanically meters out the gas at a pressure of roughly 300 to 600 pounds per square inch (20 to 41atm) and a rate of about 4 cubic feet (0.11m3) per minute. 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. 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. The high pressure of the cabin forces the wedge-shaped, plug-like door into its socket. He was carrying a bag holding 12 dozen nuts. 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. 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. That's quite high due to the 747 cockpit location on the upper deck. What rights do airline passengers with disabilities have in Europe? Electrical anti-ice is operated for all flight operations to inhibit ice build up. There should also be a suitable procedure for the closing of the door and retraction of the air bridge. 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. 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). This type of slide is in the aircraft's tailcone, and deploys after the tailcone is jettisoned by flight attendants, allowing for evacuation through the rear of the airframe. 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. height: 12'5 - 3.79 mtr max. Heads up this was for Grand Forks Flight Support who will be handeling a SunCountry 737-800 charter for UND Fighting sioux football tomorrow. 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. From Boeing's data, a 747-8 cockpit ranges from 7.56 to 7.90m above the ground . Both military and civil versions, Blimps / Airships 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. Assuming a 3,730-U.S. gallon (14,120-liter) 777 airplanes. The 757 sits very high, making it, I think, much more imposing looking. 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. 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. gallons (126,917 liters). 38.70 m / 127 ft 0 in Overall length Ground to underbelly is 226 to 246 cm on SP. Some Russian-built aircraft like the Tupolev Tu-154 have a very complicated process to activate and deploy the slides. State the rationale for any abnormalities and identify any treatment needed. This prevents it from being released until the aircraft is on the ground, where there is not such a pressure difference. Use of the aircraft attachment points may be used as a means of averting damage to the aircraft door frames and other important parts. 41 Every employer has a duty to protect so far as is reasonably practicable the health and safety of their employees whilst working at a height. 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. Transportation Section can give further advice, if required. 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 For large, wide body aircraft such as A380s and B747s a successful deployment is complete in about five to seven seconds, depending on conditions (such as temperature and winds). After this, some will swing to the side, whereas others retract towards or even into the aircraft's ceiling. Engine anti-ice is supplied to the _______. What is the height from the ground to the bottom of the cargo door on a KC-135? Because of the accidental emergency slide deployment that followed, the flight ended up being delayed for seven hours. The left wing has The reasons behind the quirk. Hope this helps. Check these cargo hold dimensions! Wing Anti-ice is operated in flight when required by icing conditions, but can also be operated for _____ on the ground for testing purposes. 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. **Laboratory Testing**\ Every type from fighters to helicopters from air forces around the globe, Classic Airliners This allows for the prompt dispatch of the plane at one end, and an equally prompt disembarking process at the other. It all makes sense when you know the reasons for it! 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. . The procedure to use this exit may involve removing a plug-type pressure bulkhead, or a swing type door that leads directly to a walkway. But there are good reasons for how high planes fly. If the battery on the wheelchair is labeled as non-spillable by the manufacturer, or if the wheelchair can be loaded, stored, secured and unloaded in an upright position in the cargo hold, the battery does not need to be removed from the wheelchair. The outboard armrest of each pilot seat is enlarged and has enhanced position controls to enable specific positioning of the armrest for uuse of the Side Stick. If the door is opened in emergency mode at an abnormal attitude (e.g. 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. 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. 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. 45 The CAA Safety Regulation Group (SRG) and HSE are both involved in enforcing existing legislation and standards at airports in line with their statutory responsibilities. Representatives of airlines, airports and ground handlers have worked with HSE in the development of this guidance. Older slides are yellow and made of neoprene/nylon fabric. What are the TSA security procedures for wheelchair users? Airline personnel can assist you with this, if you bring the tools (typically a small wrench to loosen bolts) with you. We thank you for your support and hope you'll join the largest aviation community on the web. The plane set to take off for Puerto Rico struck the tail of another JetBlue plane with no one inside. Several factors contributed to the 767's doors having different operational characteristics to other aircraft. 3) the work that is being done, for instance whether it involves handling awkward or heavy loads, the suitability of platform or step design. Where attachment points are on guard rails, the rails must be of sufficient strength to withstand foreseeable forces. Gravity will then pull the slide to the ground and it will inflate. Independent of the inflation system, all slides are equipped with at least one pressure relief device per inflation chamber. Figure 7. according to Boeing manual, the front passenger door: min. Ground Height). 10 Some airlines have already introduced door nets to protect against falls from open doors. (Continue to next page) Birds rarely fly that high, which is important, as bird strikes, though rare, can be disastrous if they happen. Boeing 747 Tail Height. 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. 2 Risks arise during maintenance of aircraft and during servicing and turnaround activities. However, other versions of the story claimed that a passenger had accidentally opened it from the inside. The minimum for these large jets would sit around . TRUE/ FALSE. Whereas, I think the 737 looks very short and squatty. 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. Typically there are two high pressure hoses attached to the valve, which are connected at the other end to aspirators. [4] Today Air Cruisers is part of Zodiac Aerospace and ultimately owned by Safran who are the world's largest provider of evacuation slides. Here are the 10 steps from arrival to take-off: 1. Have you ever witnessed an event in which an unauthorized attend has been made to open one? When on Battery Power, which Dome light can be turned on? 15 Aircraft doors should only be operated by door trained personnel such as trained ground staff, cabin crew, engineers or other competent workers. Specific requirements for different types of GSE are in BS EN 12312 (see Appendix 1 ). CV jumbo Why didn't they make the 757 wider. FUEL RECEPTACLE GROUND HEIGHT 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. Can the aircraft be flown with the Cabin Surveillance System (CSS) inoperative? 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. Powered wheelchairs andscooters almost always have to be stored underneath the airplane in the cargo hold. 43 The Lifting Operations and Lifting Equipment Regulations 1998 also apply to high loader vehicles. Sodium 138 mEq/L \ Tail and Winglet closeups with beautiful airline logos. So there has to be a balance, which is the reason for the fairly specific altitudes generally used by airliners. 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. (Maximum 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. The Boeing 737 is designed to fill the smaller jet airliners space over a given range of seats. a. And a substantial majority of small planes are flown for recreational purposes, and pilots enjoy flying lower, where they can see things below them. Potable Water pressure is provided by _________. The aircraft is equipped with ____ cabin doors. 56 Table 1 sets out some risks of serious personal injury that require immediate action, after which further action may be necessary to secure compliance and to achieve the benchmark of negligible risk of serious personal injury. Most of the time, flight attendants seamlessly operate these structures. As the thread title says - anyone know how high the door of a 737 is off the ground? An evacuation slide is an inflatable slide used to evacuate an aircraft quickly. The Fuel Quantity Display is located on the ________. Training should include aircraft manufacturers requirements, awareness of emergency chute operation and deactivation and risk of falls. for 500 U.S. gallons per minute (1,893 liters per There are also half-tie restraints which keep the inflating slide from drooping or blowing under the aircraft. 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. So again, there has to be a balance, which accounts for the altitudes generally used. 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. In such cases, safety equipment must be used and certain precautions followed. Fuel receptacle ground height for the 787-8 and other Boeing airplanes is shown in figure 7. 42 The Work at Height Regulations 2005 address all work at height where a person could fall a distance liable to cause personal injury. Let us know your thoughts and experiences in the comments. Assuming radial entry flow, determine the theoretical values for (a) the flow rate and (b) the power. Cabin / Interior Dimensions: Cabin / Interior Width: 120.1 to 122.5 inches (approximate) Cabin / Interior Height: 83 inches +- approximate. TRUE/FALSE. The Management Regulations also set out requirements for co-operation and co-ordination between employers. It is proposed that catering of the new Airbus A380 can be carried out via upper deck doors. 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. AIRCRAFT MODEL: WINGSPAN: . Any reason why? An airplane altimeter is a gauge that indicates the height of the plane above the ground. But small aircraft such as those flown by private pilots cannot fly this high, and usually do not go above 10,000 feet. This is not a factor in commercial flying. This is one way in which they are kept secure despite the strong forces that aircraft encounter inflight. Accident, incident and crash related photos, Air to Air The 787-8 is equipped with eight passenger entry 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.
