Piloting is thus assisted by providing ergonomic and simple alerts, so as to guarantee a safe trajectory for the aircraft. ## Claims ### Claim 1 A method for assisting the piloting of an aircraft, the method being implemented by a computing system comprising electronic circuitry and the method being characterized in that it comprises the following steps: detecting obstacles in an environment of the aircraft; determining a protection zone surrounding each detected obstacle; determining an initial trajectory followed by the aircraft; if the initial trajectory enters a protection zone, determining a corrected trajectory based on the initial trajectory of the aircraft and based on the protection zone surrounding each detected obstacle, such that the aircraft avoids the protection zone; applying the corrected trajectory to the aircraft; and outputting at least one haptic alert in a flight control stick of the aircraft, the haptic alert indicating a direction of deflection applied to the aircraft when applying the corrected trajectory to the aircraft. ### Claim 2 (depends on 1) The method according to claim 1, further comprising: detecting a landing zone on the initial trajectory followed by the aircraft, the detected landing zone being determined as a destination of the initial trajectory of the aircraft, and a destination of the corrected trajectory coincides with the destination of the initial trajectory. ### Claim 3 (depends on 1) The method according to claim 1, wherein dimensions of each protection zone are determined in proportion to a speed of the aircraft. ### Claim 4 (depends on 1) The method according to claim 1, wherein, when the aircraft is hovering over a point of an environment, the method further comprises: determining a static safety zone around the hovering aircraft, the static safety zone being centered on the aircraft and being static with respect to said point of the environment; detecting a movement of the hovering aircraft outside the static safety zone; repositioning the hovering aircraft in the center of the static safety zone; and outputting at least one haptic alert in a flight control stick of the aircraft, the haptic alert indicating a direction of deflection applied to the aircraft when repositioning the aircraft in a center of the static safety zone. ### Claim 5 (depends on 1) The method according to claim 1, wherein the initial trajectory is determined using data from sensors and detectors chosen from among: an inertial unit, a camera, a lidar, a radar, a satellite positioning system, and an attitude determination system. ### Claim 6 (depends on 1) A non-transient storage medium on which there is stored a computer program comprising program code instructions for executing the method according to claim 1 when said instructions are read from said non-transient storage medium and executed by a processor. ### Claim 7 A computing system comprising electronic circuitry configured to implement assistance with the piloting of an aircraft, comprising the following steps: detecting obstacles in an environment of the aircraft; determining a protection zone surrounding each detected obstacle; determining an initial trajectory followed by the aircraft; if the initial trajectory enters a protection zone, determining a corrected trajectory based on the initial trajectory of the aircraft and based on the protection zone surrounding each detected obstacle, such that the aircraft avoids the protection zone; applying the corrected trajectory to the aircraft; and outputting at least one haptic alert in a flight control stick of the aircraft, the haptic alert indicating a direction of deflection applied to the aircraft when applying the corrected trajectory to the aircraft.
