Piloting assistance method for aircraft

The present invention relates to a piloting assistance method for an aircraft, the method consisting in using data from at least one active telemeter sensor (A) in order to construct a sensor safety cordon (B) for avoiding the terrain and obstacles that are overflown. The method; defines and calculates angular sectors (w) over the field of regard facing the pilot; constructs a terrain safety cordon (D) using at least one terrain database (C); for at least some of the angular sectors (w), constructs a hybrid safety cordon (E) that, in each of the angular sectors (w) in question, makes use of the higher of the sensor and terrain safety cordons (B, D); and displays one of the cordons selected from: the hybrid safety cordon (E), the terrain safety cordon (D), and the sensor safety cordon (B).
