Abstract
The invention relates to a method and device for piloting a pitching aircraft. The inventive device () comprises: means () for receiving an ordered load factor (NZc); means () for estimating a load factor (NZcg) that is applied to the aircraft; a means () for calculating a control order for a means () for deflecting a control surface () of the aircraft, taking account of at least the following expression K1·NZc+K2·NZcg, K1 and K2 representing gain values; means () for determining the Mach number; means () for determining the angle of incidence; means () for comparing the angle of incidence with a reference value; and means () for determining a modified gain value (ΔK2) with the aid of the Mach number and the angle of incidence if said angle of incidence is greater than the reference value, said modified gain value (ΔK2) replacing gain value K2 in the calculation performed by the calculation means ().
