Patent ID: 7499773

Claim:
A method of assisting the piloting of an aircraft in which a guard curve is determined as a function of the resources of the aircraft, wherein: the position of an obstacle or a point of the terrain situated in front of the aircraft is measured by telemetry, a distance D is calculated between the guard curve and the obstacle or terrain point, the points of a piloting curve (CP) for presenting to the pilot are calculated, in a plurality of angular sectors ( 30 ) predefined as a function of a field of regard (FOR), by selecting for each vertical profile of the terrain in a predefined angular sector, the point of the profile that corresponds to a maximum pull-up order, if such a point exists, and if there is no such point, by selecting the point of the profile that corresponds to a minimum pull-down order, the pull-down or pull-up order ⅆ φ ⅆ t being determined using the formula: ⅆ φ ⅆ t = G * ( D + τ * ⅆ D ⅆ t ) where G is a gain and τ is a warning time, where dD is the variation in the distance D between two successive time markers, and where dt is the time that elapses between said two time markers, and a pull-up order is produced when the sum ( D + τ * ⅆ D ⅆ t ) is negative, and a pull-down order is produced when the sum ( D + τ * ⅆ D ⅆ t ) is positive.
