Maximum Landing Weight
The maximum landing weight (MLW) is the maximum aircraft gross weight due to design or operational limitations at which an aircraft is permitted to land. The MLW is set in order to ensure safe landings; if an aircraft weighs too heavy during touchdown, it may suffer structural damage or even break apart upon landing. Aircraft also have a maximum take-off weight, which is almost always higher than the maximum landing weight, so that an aircraft can weigh less upon landing due to burning fuel during the flight. The operation landing weight may be limited to a weight lower than the maximum landing weight by the most restrictive of the following requirements: * Aircraft performance requirements for a given altitude and temperature: :*landing field length requirements, :*approach and landing climb requirements. * Noise requirements If the flight has been of unusually short duration, such as due to an emergency just after takeoff requiring a return to the airport, it may be necessary t ...

Aircraft Gross Weight
The aircraft gross weight (also known as the all-up weight and abbreviated AUW) is the total aircraft weight at ''any moment'' during the flight or ground operation. An aircraft's gross weight will decrease during a flight due to fuel and oil consumption. An aircraft's gross weight may also vary during a flight due to payload dropping or in-flight refuelling. At the moment of releasing its brakes, the gross weight of an aircraft is equal to its takeoff weight. During flight, an aircraft's gross weight is referred to as the ''en-route weight'' or ''in-flight weight''. Design weight limits (structural design weights) An aircraft's gross weight is limited by several weight restrictions in order to avoid overloading its structure or to avoid unacceptable performance or handling qualities while in operation. Aircraft gross weight limits are established during an aircraft's design and certification period and are laid down in the aircraft's type certificate and manufacturer specific ...

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Maximum Take-off Weight
The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft is the maximum weight at which the pilot is allowed to attempt to takeoff, take off, due to structural or other limits. The analogous term for rockets is gross lift-off mass, or GLOW. MTOW is usually specified in units of kilograms or pounds. MTOW is the heaviest weight at which the aircraft has been shown to meet all the airworthiness requirements applicable to it. MTOW of an aircraft is fixed and does not vary with altitude, air temperature, or the length of the runway to be used for takeoff or landing. Maximum permissible takeoff weight or "regulated takeoff weight", varies according to flap setting, altitude, air temperature, length of runway and other factors. It is different from one takeoff to the next, but can never be higher than the MTOW. Certification standards Certification standards applicable to the airworthiness of an aircraft contain many requ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Dumping
Fuel dumping (or a fuel jettison) is a procedure used by aircraft in certain emergency situations before a return to the airport shortly after takeoff, or before landing short of the intended destination (emergency landing) to reduce the aircraft's weight. Aircraft fuel dump Weight issues Aircraft have two major types of weight limits: the maximum takeoff weight and the maximum structural landing weight, with the maximum structural landing weight almost always being the lower of the two. This allows an aircraft on a normal, routine flight to take off at the higher weight, consume fuel en route, and arrive at a lower weight. It is the abnormal, non-routine flight where landing weight can be a problem. If a flight takes off at the maximum takeoff weight and then must land well before its destination, even returning immediately after takeoff to the departure airport (for example, because of mechanical problems or a passenger medical problem), it will contain more fuel than was ...

Air Canada
Air Canada is the flag carrier and the largest airline of Canada by the size and passengers carried. Air Canada maintains its headquarters in the borough of Saint-Laurent, Montreal, Quebec. The airline, founded in 1937, provides scheduled and charter air transport for passengers and cargo to 222 destinations worldwide. It is a founding member of the Star Alliance. Air Canada's major hubs are at Montréal–Trudeau International Airport (YUL), Toronto Pearson International Airport (YYZ), Calgary International Airport (YYC), and Vancouver International Airport (YVR). The airline's regional service is Air Canada Express. Canada's national airline originated from the Canadian federal government's 1936 creation of Trans-Canada Air Lines ( TCA), which began operating its first transcontinental flight routes in 1938. In 1965, TCA was renamed Air Canada following government approval. After the deregulation of the Canadian airline market in the 1980s, the airline was privatized in 198 ...

Boeing 767
The Boeing 767 is an American wide-body aircraft developed and manufactured by Boeing Commercial Airplanes. The aircraft was launched as the 7X7 program on July 14, 1978, the prototype first flew on September 26, 1981, and it was certified on July 30, 1982. The original 767-200 entered service on September 8, 1982, with United Airlines, and the extended-range 767-200ER in 1984. It was stretched into the in October 1986, followed by the 767-300ER in 1988, the most popular variant. The 767-300F, a production Cargo aircraft, freighter version, debuted in October 1995. It was stretched again into the 767-400ER from September 2000. To complement the larger Boeing 747, 747, it has a seven-abreast cross-section, accommodating smaller LD2 unit load device, ULD cargo containers. The 767 is Boeing's first wide-body twinjet, powered by General Electric CF6, Rolls-Royce RB211, or Pratt & Whitney JT9D turbofans. JT9D engines were eventually replaced by Pratt & Whitney PW4000, PW4000 engi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holding (aeronautics)
In aviation, holding (or flying a hold) is a maneuver designed to delay an aircraft already in flight while keeping it within a specified airspace. Implementation A holding pattern for instrument flight rules (IFR) aircraft is usually a racetrack pattern based on a ''holding fix''. This ''fix'' can be a radio beacon such as a non-directional beacon (NDB) or VHF omnidirectional range (VOR). The fix is the start of the first turn of the racetrack pattern. Aircraft will fly towards the fix, and once there will enter a predefined racetrack pattern. A standard holding pattern uses right-hand turns and takes approximately 4 minutes to complete (one minute for each 180-degree turn, and two one-minute straight ahead sections). Deviations from this pattern can happen if long delays are expected; longer legs (usually two or three minutes) may be used, or aircraft with distance measuring equipment (DME) may be assigned patterns with legs defined in nautical miles rather than minutes. ...

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aeroflot Flight 1492
Aeroflot Flight 1492 was a scheduled domestic passenger flight operated by Aeroflot from Moscow–Sheremetyevo to Murmansk, Russia. On 5 May 2019, the Sukhoi Superjet 100 aircraft operating the flight was climbing out when it was struck by lightning. The aircraft suffered an electrical failure and returned to Sheremetyevo for an emergency landing. It bounced on landing and touched down hard, causing the landing gear to collapse, fuel to spill out of the wings, and a fire to erupt. The fire engulfed the rear of the aircraft, killing 41 of the 78 occupants. Aircraft The aircraft was a Russian-built Sukhoi Superjet 100, MSN (manufacturer's serial number) 95135, and was registered as RA-89098. It was delivered new to Aeroflot on 27 September 2017 and had accumulated 2,710 flight hours and 1,658 cycles (a flight cycle consists of a take-off and a landing) before the accident. Aeroflot Superjets are configured with 87 passenger seats, 12 in business and 75 in economy. Accident Flig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
