Airplane gliding occurs when all the engines of an aircraft shut down, but the wings are still functional and can be used for a controlled descent. This is a very rare condition in multi-engine airliners, [1] though it is the obvious result when a single-engine airplane experiences engine failure.
Another way of putting it, the airplane swaps ends. This is a ground loop." [4] The Schleicher ASK 23 is a single-seat glider suitable for new pilots. It has a nose-wheel, and its main wheel is behind the centre of gravity. This avoids the risk of ground-looping at commencement of takeoff in a crosswind behind a tow plane.
Glider pilots routinely practice flying in wingtip vortices when they do a maneuver called "boxing the wake". This involves descending from the higher to lower position behind a tow plane. This is followed by making a rectangular figure by holding the glider at high and low points away from the towing plane before coming back up through the ...
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".
The pilot will use the polar curve information for the particular glider to derive the exact speeds to fly, minimum sink or maximum L/D, depending on the lift and sink conditions in which the glider is flying. A speed to fly ring (known as a 'MacCready Ring'), which is fitted around the aircraft's variometer, will indicate the optimum airspeed ...
The Wright brothers are credited with developing the first practical control surfaces. It is a main part of their patent on flying. [1] Unlike modern control surfaces, they used wing warping. [2]
Pilot's view of a Schempp-Hirth Janus-C glider. The yaw string (red wool) on the canopy and the turn and bank indicator (top center of the instrument panel) both show the glider is not in coordinated flight. The glider is slipping slightly nose-left. Coordinated flight can be restored by the pilot applying pressure to the right rudder pedal.
However, gliding can be achieved with a flat wing, as with a simple paper plane, [2] or even with card-throwing. However, some aircraft with lifting bodies and animals such as the flying snake can achieve gliding flight without any wings by creating a flattened surface underneath.
