- the modified flight plan 36 thus generated is then formed from the current flight plan up to the first characteristic point 24, then of the loop trajectory 32 calculated and iterated one or more times, and finally of the end of the current flight plan, taken either from the first characteristic point 24, or from the geographical position corresponding to reaching at least minus one of the exit conditions, as shown in the example of FIG. 3, where the geographic position corresponding to reaching the exit condition is represented by a loop exit point 115.
- the flight management assistance system 20 estimates, during step 130 and via its estimation module 38, at least one aeronautical quantity at at least one point of the modified flight plan 36, typically at at least one point of the calculated loop path 32, in order to allow the user to best predict what the flight conditions will be when the aircraft 10 follows the calculated loop path 32 .
- the calculated aeronautical quantity is for example the quantity of remaining energy, the temporal instant of passage or the speed of the aircraft 10 at said corresponding point of the modified flight plan 36, or the distance between said corresponding point of the flight plane. modified flight 36 and another point on the modified flight plan 36.
- the flight management assistance system 20 determines, during step 140 and via its determination module 40, the maximum number of iteration (s) of the loop trajectory 32, this preferably as a function of at least one criterion, such as the amount of remaining energy, the maximum time to reach a predefined later point of the flight plan, and the maximum flight time along the loop path 32.
- the determination step 140 is performed after the generation step 120 and the estimation step 130, and those skilled in the art will then understand that if the number of iterations of the loop path 32, planned during the stages of calculation 110 and generation 120 is greater than the maximum number of iterations determined during step 140, said expected number will then be clipped, that is to say corrected to be equal to the maximum number of iterations, and therefore not exceed it.
- the determining step is performed at the same time as the calculating step 110; or alternatively between the calculation step 110 and the generation step 120.
- the flight management assistance system 20 finally displays, during step 150 and via its display module 42, the modified flight plan 36 generated during generation step 120, as well as any quantities aeronautics estimated during the estimation step 130.
- FIG. 3 A schematic example of display is illustrated in FIG. 3, where a person skilled in the art will observe that the part already flown from the modified flight plan 36 is shown in dotted lines, while the part remaining to be flown from the modified flight plan 36 is shown in solid, thick lines.
- the flight management assistance system 20 returns to the initial acquisition step 100, in order to acquire any new characteristic points, to modify the trajectory loop 32 calculated, or to calculate a new loop path 32.
- the flight management assistance system 20 allows the user, such as the pilot of the aircraft 10, to more easily carry out a or several loops during flight with said aircraft 10.
- the flight management aid system 20 then makes it possible to more easily calculate a loop trajectory 32 which can be flown from the current flight plan, and as an optional addition to also provide the user with predictions of value d. one or more aeronautical quantities along the modified flight plan 36, and in particular along the calculated loop path 32.
- the flight management assistance system 20 makes it possible to significantly reduce the cognitive load for the user who no longer has to form a mental image of what the aircraft 10 is going to do for to be able to estimate the future flight situation as the loop trajectory 32 is followed, and in particular to be able to estimate at each end of the turn, that is to say at each end of an iteration of the trajectory of loop 32, the possibility of making an additional turn, that is to say of performing a new iteration of the loop path 32.
- the flight management aid system 20 makes it possible as an optional addition to know, in addition and in advance, the number of iterations that can be carried out of the loop trajectory 32, to construct the loop trajectory 32 with a possible transition to move to another point on the flight plan, in particular when a condition of exit based on a geographic exit position is acquired, and further define one or more exit conditions from said loop path 32.
- the cognitive load for the user is then greatly reduced, which makes it possible to significantly improve the safety of the flight of the aircraft 10. It is thus conceived that the method of assistance to the management and the system of assistance to. the flight management 20 according to the invention make it possible to further improve the assistance in piloting the aircraft 10, in order to make the flight of the aircraft 10 safer, in particular when performing loop (s) during of theft.
