Claim:
1. A method of determining and displaying on a display device of a system for anti-collision monitoring of an aircraft, limits of flight margins in relation to obstructions located in a flight zone, the monitoring system generating collision alerts for obstructions located in a protection envelope of the aircraft and being able to calculate at least one flight maneuver predefined in a vertical plane, the method comprising: determining current flight parameters comprising current position, altitude, heading, speed including vertical speed, angle of approach, and roll rate of the aircraft, with avionic systems transmitting the aircraft's flight parameters in real time, determining a current trajectory comprising a vertical trajectory in the vertical plane extrapolated from said current flight parameters with the anti-collision system, calculating a plurality of radial trajectories in vertical planes distributed over the flight zone with the anti-collision monitoring system, said radial trajectories being rectilinear prolongations, beyond the protection envelope, of the current vertical trajectory of the aircraft in the vertical planes according to an azimuthal angular interval defined in the system, calculating and displaying on the display device in the flight zone a first monitoring zone with the anti-collision monitoring system in a form of a sector of disk surrounding the current trajectory of the aircraft and a second monitoring zone outside of the first monitoring zone in the flight zone, and the second monitoring zone being formed by a left lateral sector and a right lateral sector with respect to a direction of movement of the aircraft, calculating flight maneuvers of a first type with the anti-collision monitoring system, wherein the first type of flight maneuver includes three flight phases: based on the radial trajectories belonging to the first monitoring zone, and calculating flight maneuvers of a second type with the anti-collision monitoring system, wherein the second type of flight maneuver includes three phases: calculating the parameters for carrying out the flight maneuvers with the anti-collision monitoring system, comprising a point of intersection with an obstruction, based on each radial trajectory, said parameters comprising the position of the point of initiation of the maneuver, and displaying on the display device the current position of the aircraft and the position of the point of initiation of the flight maneuver closest to the current position of the aircraft for each obstruction and for each radial trajectory, said points of initiation of the flight maneuvers of all the radial trajectories representing flight margin limits of the aircraft at its current position in relation to the obstructions on the flight zone, wherein the display device displays the delimitations between the first flight zone and the second flight zone.
