A US certification standard for civil airplanes up to 12,500 lb (5,700 kg) maximum takeoff weight is Part 23 of the Federal Aviation Regulations, applicable to airplanes in the normal, utility and acrobatic categories. Part 23, §23.221 requires that single-engine airplanes must demonstrate recovery from either a one-turn spin if intentional ...
Colgan Air Flight 3407 (marketed as Continental Connection Flight 3407) was a scheduled passenger flight from Newark, New Jersey to Buffalo, New York on February 12, 2009. . Approaching Buffalo, the aircraft, a Bombardier Q400, entered an aerodynamic stall from which it did not recover and crashed into a house at 6038 Long Street in Clarence Center, New York at 10:17 pm EST (03:17 UTC), about ...

In aerobatics, the cobra maneuver (or just the cobra), also called dynamic deceleration, [1] among other names (see § Etymology), is a dramatic and demanding maneuver in which an airplane flying at a moderate speed abruptly raises its nose momentarily to a vertical and slightly past vertical attitude, causing an extremely high angle of attack and making the plane into a full-body air brake ...
1/4 loop (pull or push) to vertical, as momentum/airspeed decreases, rudder is applied and the aircraft rotates around its yaw axis, the nose falls through the horizon and points towards the ground, a momentary pause is made to draw the vertical down line, and 1/4 loop to level flight.
Aircraft flight mechanics are relevant to fixed wing (gliders, aeroplanes) and rotary wing (helicopters) aircraft.An aeroplane (airplane in US usage), is defined in ICAO Document 9110 as, "a power-driven heavier than air aircraft, deriving its lift chiefly from aerodynamic reactions on surface which remain fixed under given conditions of flight".
[8] [9] Debris fell through the roof of a private home [4] and significantly damaged a parked vehicle. [10] The engine failure resulted in an in-flight engine fire, extensive damage to the engine nacelle, and minor damage to the fuselage. [11] Passengers also recorded video of the engine nacelle damage and in-flight fire and posted these to ...
In another variation, the flight approaches from the south, preferably near sundown, and one of the aircraft will suddenly split off to the west, flying into the sunset. [9] In all cases, the aircraft performing the pull-up, split off, or missing from the formation is honoring the person (or persons) who has died, and is representing their ...
