Abstract: The invention relates to a method for assisting the piloting of an aircraft in the vicinity of a landing or takeoff point, by: determining the locus of entry and/or exit points for a given approach and/or departure altitude that are not safe for reaching the landing and/or takeoff point; and presenting a diagram including said locus on a display device.

Abstract: A system (20) on board or suitable for use on board an aircraft to define an aircraft track having a plurality of segments, the system includes a display unit (10) arranged to display an image (11) containing a representation of the footprint of a segment (S, S1, S2) in a plane or level; an analog input member (17) for inputting altitude data (A) into a computer (13) connected to the display unit; and a calculation program or module arranged to determine a representation (C1, C2, PR1, PR2) of relief that is dangerous for a flight altitude equal to the value of the altitude data (A), and to superimpose (or include) the representation on (in) the image (11).

Abstract: A method is provided for assisting the piloting of a rotorcraft in which vertical speed variation (DVZ) of the rotorcraft is determined as a function of a horizontal speed variation (DVH) of the aircraft and as a function of data representative of the power (W) absorbed for providing the rotorcraft with lift and forward advance, the ratio between variation speed vertical (DVZ) and the horizontal speed (VH) of the rotorcraft is calculated, and a piloting assistance symbol is presented on a display in a position (?) that is a function of the ratio.
