The Polish Air Force is the aerial warfare branch of the Polish Armed Forces. Until July 2004 it was officially known as Wojska Lotnicze i Obrony Powietrznej. In 2014 it consisted of roughly 26,000 military personnel and about 475 aircraft, distributed among ten bases throughout Poland.
The Mil Mi-8 is a medium twin-turbine helicopter, originally designed by the Soviet Central Aerohydrodynamic Institute (TsAGI) in the 1960s and introduced into the Soviet Air Force in 1968. Russian production of the aircraft model still continues as of 2024. In addition to its most common role as a transport helicopter, the Mi-8 is also used as an airborne command post, armed gunship, and reconnaissance platform.
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".
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 which could severely affect the aircraft's performance.
American Eagle Flight 4184, officially operating as Simmons Airlines Flight 4184, was a scheduled domestic passenger flight from Indianapolis, Indiana, to Chicago, Illinois, United States. On October 31, 1994, the ATR 72 performing this route flew into severe icing conditions, lost control and crashed into a field, killing all 68 people on board in the high-speed impact.
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, killing all 29 people on board.
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. Some trees have seeds that have wing-like structures that enable the seed to spin to the ground in autorotation, which helps the seeds to disseminate over a wider area.
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 and its fleet retired.
On 7 April 2013, a Mil Mi-8 helicopter operated by Helicópteros del Pacífico (Helipac) broke up in flight and crashed en route from Iquitos to a Perenco site near the Curaray River, in the Loreto Region of Peru. All 13 people on board were killed. The occupants, all Peruvian nationals, were nine passengers and four crew. Among the passengers were Perenco workers and other contractors.
Pulkovo Aviation Enterprise Flight 9045 was a cargo flight that crashed on approach to Nalchik while carrying 12,515 kg (27,591 lb) of coins from the Saint Petersburg Mint, killing all 13 occupants.
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 American country music duo 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.
