The invention concerns a method for improving maneuverability of an aircraft during approach phases before landing followed by flare-out, the aircraft being equipped with air brakes. The invention is characterized in that it consists in shifting the air brakes into a first curved extended position (CFAA) during the first approach phase before landing and, based on a parameter representing a given altitude and in case of steep-gradient approach, in shifting them to a second position more retracted than the first curved position (CFSA) so as to obtain a flare-out enabling the same incidence to be maintained, corresponding in case of steep-gradient approach to obtain a flare-out with external piloting references usual during steep-gradient approach.
Le procédé améliore la manoeuvrabilité d'un aéronef lors des phases d'approche avant l'atterrissage puis d'arrondi, l'aéronef étant équipé d'aérofreins. Selon le procédé, on met les aérofreins dans une première position déployée courbe CFAA lors de la phase d'approche avant l'atterrissage et, en fonction d'un paramètre représentatif d'une altitude donnée et en cas d'approche sous forte pente, on commande leur passage à une seconde position plus rétractée que la première position courbe (CFSA) de manière à obtenir un arrondi permettant de conserver sensiblement la même incidence, correspondant en cas d'approche sous forte pente à obtenir un arrondi avec des références extérieures de pilotage habituelles pendant la phase d'arrondi.
