Procedure for aiding takeoff of an aircraft.

摘要

Procedure for aiding takeoff of an aircraft (1) comprising a trailing edge flaps (7) and a leading edge slats (8) and an adjustable horizontal tailplane (2) to which are articulated about elevators (4) process according to which: - VR value aircraft speed is prespecified called rolling speed, which must begin rolling takeoff, having said value VR be within a range of values ​​of speed imposed by the regulations; and - is applied to said aircraft (1) a pitch command for aiding takeoff deflecting said adjustable horizontal tailplane (2) with an angle whose value is predetermined, characterized in that: - in said range of speed values, is chosen arbitrarily a reference speed VRref and is determined, for this reference speed VRref, the value (iH1) of the angle of deflection of said adjustable horizontal tailplane only in function of the longitudinal position (cg) of the center of gravity (CG) of said aircraft takeoff; - the difference between said rotation speed VR and said reference speed VRref is determined; and - said pitch command aid takeoff is corrected according to said speed difference, to make it similar to a takeoff to another, the behavior of the aircraft in rolling.
