Maximum Landing Weight
The maximum landing weight (MLW), also known as the maximum structural landing weight or maximum structural landing mass, 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 ...

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 specifi ...

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; i.e. "going in circles." 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 ...

Aircraft Operations
An aircraft ( 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 the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." 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, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeroflot Flight 1492
Aeroflot Flight 1492 was a scheduled domestic passenger flight operated by Aeroflot from Sheremetyevo International Airport, Moscow–Sheremetyevo to Murmansk Airport, Murmansk, Russia. On 5 May 2019, the Sukhoi Superjet 100 aircraft operating the flight was climbout, climbing out when it was struck by Lightning strike, lightning. The aircraft suffered an electrical failure and returned to Sheremetyevo for an emergency landing. It bounced landing, 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 aircraft registration, registered as RA-89098. The aircraft had accumulated 2,710 flight hours and 1,658 cycles before the accident. Aeroflot Superjets are configured with 87 passenger seats, 12 in business class and ...

Global News
Global News is the news and Current affairs (news format), current affairs division of the Canadian Global Television Network. The network is owned by Corus Entertainment, which oversees all of the network's national news programming as well as local news on its 21 owned-and-operated stations. Corus currently operates one all-news radio station, and previously operated several talk radio stations, under the "Global News Radio" brand. The same division also operates a news website under the same brand. National programs Although Global stations had always carried local news in various forms, the first tentative steps towards a national presence came in 1994 with the launch of ''First National (television show), First National'' with Peter Kent, an early-evening program focusing on national and international news but airing only in central Canada. After acquiring the Western International Communications (WIC) group of stations, Global cancelled ''First National'' in February 2001 ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Fighter Aircraft
Fighter aircraft (early on also ''pursuit aircraft'') are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air supremacy, air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical bombing, tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. 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 aircraft, ground attack and some types, such as fighter-b ...

Spanish Air Force
The Spanish Air and Space Force () is the aerial and space warfare branch of the Spanish Armed Forces. History Early stages Hot air balloons have been used with military purposes in Spain as far back as 1896. In 1905, with the help of Alfredo Kindelán, Leonardo Torres Quevedo directed the construction of the first Spanish dirigible in the Army Military Aerostatics Service, created in 1896 and located in Guadalajara. The new airship was completed successfully in 1908 and, named 'Torres Quevedo', made numerous test and exhibition flights.Francisco A. González Redondo''Leonardo Torres Quevedo, 1902–1908. The Foundations for 100 years of Airship designs''In book: Proceedings of the 7th International Airship Convention, pp.1–12, Publisher: German Society for Aeronautics and Astronautics (DGLR), October 2008.

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 main types of weight limits: the maximum takeoff weight is composed of DOW (Dry Operating Weight) plus Payload (passengers and cargo), collectively the ZFW (Zero Fuel Weight), plus the trip fuel, contingency, alternate, final reserve and the block fuel (taxi fuel), 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 a higher weight, consume fuel en route, and arrive at a lower weight. It is an 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 w ...
