Method and device for detecting vertical gusts of wind and application thereof to the pitch-attitude control of an aircraft

摘要

An apparatus and method for detecting vertical gusts of wind on board an aircraft in cruising flight is disclosed. The method includes the steps of: calculating an absolute value (|&agr;-&thgr;. vertline.) of a difference between a pair of first differentials with respect to time (&agr; and &thgr;) of a current incidence &agr; and a current pitch attitude &thgr; of the aircraft, comparing the absolute value to an upper threshold (Ss), comparing a current Mach number (M) of the aircraft to a Mach number threshold (Mo), and generating an electrical signal that represents presence of a vertical gust of wind when the absolute value is above the upper threshold, when the current Mach number is above the Mach number threshold, and when aerodynamic flaps and slats of the aircraft are in a clean configuration.
