Aviation is the design, development, production, operation, and use of aircraft, especially heavier-than-air aircraft. Articles related to aviation include:
Air Florida Flight 90 was a scheduled U.S. domestic passenger flight operated by Air Florida from Washington National Airport to Fort Lauderdale–Hollywood International Airport, with an intermediate stopover at Tampa International Airport. On January 13, 1982, the Boeing 737-222 registered as N62AF crashed into the 14th Street Bridge over the Potomac River.

In aeronautics, a descent is any time period during air travel where an aircraft decreases altitude, and is the opposite of an ascent or climb.
The AgustaWestlandAW609, formerly the Bell/Agusta BA609, is a twin-engined tiltrotor VTOL aircraft with a configuration similar to that of the Bell Boeing V-22 Osprey. It is capable of landing vertically like a helicopter while having a range and speed in excess of conventional rotorcraft. The AW609 is aimed at the civil aviation market, in particular VIP customers and offshore oil and gas operators.
The Robinson R22 is a two-seat, two-bladed, single-engined, light utility helicopter manufactured by Robinson Helicopter Company. It was designed in 1973 by Frank D. Robinson, and has been in production since 1979.
USAir Flight 405 was a regularly scheduled domestic passenger flight between LaGuardia Airport in Queens, New York City, New York, and Cleveland, Ohio. On March 22, 1992, a USAir Fokker F28, registration N485US, flying the route, crashed in poor weather in a partially inverted position in Flushing Bay, shortly after liftoff from LaGuardia. The undercarriage lifted off from the runway, but the airplane failed to gain lift, flying only several meters above the ground. The aircraft then veered off the runway and hit several obstructions before coming to rest in Flushing Bay, just beyond the end of the runway. Of the 51 people on board, 27 were killed, including the captain and a member of the cabin crew.
The FAA states "The height–velocity diagram or H/V curve is a graph charting the safe/unsafe flight profiles relevant to a specific helicopter. As operation outside the safe area of the chart can be fatal in the event of a power or transmission failure it is sometimes referred to as the dead man's curve." The EASA refers to it as the "height/velocity avoid curve".
Air Ontario Flight 1363 was a scheduled Air Ontario passenger flight which crashed near Dryden, Ontario, on 10 March 1989 shortly after takeoff from Dryden Regional Airport. The aircraft was a Fokker F28-1000 Fellowship twin jet. It crashed after only 49 seconds because it was not able to attain sufficient altitude to clear the trees beyond the end of the runway, due to ice and snow on the wings.
In aviation, icing conditions are atmospheric conditions that can lead to the formation of water ice on an aircraft. Ice accretion and accumulation can affect the external surfaces of an aircraft – in which case it is referred to as airframe icing – or the engine, resulting in carburetor icing, air inlet icing or more generically engine icing. These phenomena may possibly but do not necessarily occur together. Both airframe and engine icing have resulted in numerous fatal accidents in aviation history.
A deicing boot is a type of ice protection system installed on aircraft surfaces to permit a mechanical deicing in flight. Such boots are generally installed on the leading edges of wings and control surfaces as these areas are most likely to accumulate ice and any contamination could severely affect the aircraft's performance.
In aeronautics, ice protection systems keep atmospheric moisture from accumulating on aircraft surfaces, such as wings, propellers, rotor blades, engine intakes, and environmental control intakes. Ice buildup can change the shape of airfoils and flight control surfaces, degrading control and handling characteristics as well as performance. An anti-icing, de-icing, or ice protection system either prevents formation of ice, or enables the aircraft to shed the ice before it becomes dangerous.
Comair Flight 3272 was a Comair flight from Cincinnati to Detroit on Thursday, January 9, 1997. While on approach for landing, the Embraer EMB 120 Brasilia aircraft crashed nose-down 18 miles (29 km) southwest of Detroit Metropolitan Wayne County Airport at 15:54 EST. All 29 aboard, 26 passengers and three crew members, were killed.
Autorotation is a state of flight in which the main rotor system of a helicopter or other rotary-wing aircraft turns by the action of air moving up through the rotor, as with an autogyro, rather than engine power driving the rotor. The term autorotation dates to a period of early helicopter development between 1915 and 1920, and refers to the rotors turning without the engine. It is analogous to the gliding flight of a fixed-wing aircraft. Autorotation has also evolved to be used by certain trees as a means of disseminating their seeds further.
The 36th Special Regiment of Aviation Transport was a special aviation regiment of the Polish Air Force, established in 1945. All of its aircraft were for national public use, the most important being transport of Polish politicians and Ministry of National Defence highest officials & forces commanders. It was headquartered at the 1st Air Base at Warsaw Chopin Airport. Between 1947 and 1974 it operated as Special Air Regiment, earlier as Government Transport Squadron. It was shut down in 2011 after the 2010 Polish Air Force Tu-154 crash accident report found serious deficiencies in its organization and training, and its aircraft retired.
On 8 September 2017, a Schweizer 269C helicopter crashed after an uncontrolled descent during a power-off landing attempt at the Flying W Airport in Medford, New Jersey, United States. The aircraft had experienced engine trouble during a local sightseeing flight for the benefit of passenger Troy Gentry, cofounder and member of the popular American country music band Montgomery Gentry, which was scheduled to perform at a resort at the airport later that day. The pilot died at the scene; Gentry was pronounced dead after being taken to a hospital.
Ryan International Airlines Flight 590 was a cargo flight carrying mail for the United States Postal Service from Greater Buffalo International Airport (BUF) in Buffalo, New York, to Indianapolis International Airport (IND) in Indiana, with a stopover at Cleveland Hopkins International Airport (CLE) in Cleveland, Ohio. On February 17, 1991, the McDonnell Douglas DC-9-15RC operating the flight crashed on takeoff from Cleveland during icing conditions. Both pilots, the aircraft's only occupants, were killed. The National Transportation Safety Board (NTSB) determined that the causes of the crash were the flight crew failing to deice their aircraft, and the inexperience of the Federal Aviation Administration (FAA), McDonnell Douglas, and Ryan International Airlines with icing condition on DC-9-10 aircraft.
Siberian Light Aviation Flight 42 was a domestic Russian scheduled passenger flight from Kedrovy to Tomsk, both in Tomsk Oblast in Siberia. On 16 July 2021, the Antonov An-28 operating the flight suffered icing in the engines leading to a dual engine failure 10 minutes into the flight and crash landed in a remote area in the Vasyugan Swamp in the Bakcharsky District. The pilot suffered a broken leg requiring surgery, but all of the remaining passengers and crew escaped with only minor injuries. An investigation ultimately concluded that the pilots of the aircraft had not activated the anti-icing system, which led to an accumulation of ice, resulting in engine failure. Initially praised as a hero for his handling of the incident, the pilot of the flight was ultimately criminally charged for violating safety protocols, leading to the crash.
In aviation, ground deicing of aircraft is the process of removing surface frost, ice or frozen contaminants on aircraft surfaces before an aircraft takes off. This prevents even a small amount of surface frost or ice on aircraft surfaces from severely impacting flight performance. Frozen contaminants on surfaces can also break off in flight, damaging engines or control surfaces.
