Method and device for ensuring the safety of a low-altitude flight of an aircraft
First Claim
1. A method of ensuring the safety of a low-altitude flight of an aircraft which is guided along a flight trajectory, comprising a lateral trajectory and a vertical trajectory, said method comprising:
- determining current flight conditions;
realizing a function for global and autonomous monitoring of said low-altitude flight of the aircraft, with the aid of said current flight conditions, making it possible to preserve the integrity of said aircraft during said flight; and
presenting the results of the monitoring function thus realized to an operator,wherein, to realize said monitoring function, a first monitoring is realized so as to verify compatibility of a precomputed vertical trajectory with an updated theoretical performance of the aircraft,wherein, to realize said first monitoring;
a protection profile is formed with the aid of computation parameters relating to the aircraft and of exterior parameters, which are measured and updated, wherein said protection profile depends on a capacity of the aircraft to perform a resource at constant speed and at maximum slope,the protection profile is projected onto the vertical trajectory from a current position of the aircraft, downstream, along said vertical trajectory, anda check is carried out to verify if said protection profile thus projected tangentially intercepts said vertical trajectory, and a signal for warning a pilot of the aircraft is emitted when said protection profile tangentially intercepts said vertical trajectory.
