Abstract: A method of determining a vertical path of an aircraft from its current position, an associated computer program product and a determining system are disclosed. In one aspect, the method includes determining a vertical path of the aircraft including determining an initial path segment and N following path segments, composing the vertical path of the aircraft from the determined path segments and freezing this vertical path. The method further includes determining a status of each of the altitude constraints along the entire vertical path of the aircraft, each status being chosen between an achievable status when the corresponding altitude constraint is satisfied and a missed status otherwise, and displaying the vertical path of the aircraft and statuses of the determined altitude constraints to the operator.

Abstract: An aid method for controlling the energy situation of an aircraft. The method includes determining (i) an energy meeting point corresponding to a constraint point, (ii) a meeting type based on the constraint at the constraint point, (iii) an energy state of the aircraft relative to a reference altitude profile determined by a flight management system, (iv) a high-energy joining profile representative of a future path of the aircraft with an energy dissipation strategy, and (v) energy deviations relative to the high-energy joining profile. Determining the high energy joining profile is carried out backwards depending on the type of meeting and the energy state of the aircraft. The energy deviations are displayed to an operator of the aircraft.

Abstract: This method comprises a step of determining a reference profile along a lateral trajectory precalculated comprising searching, in the precalculated lateral trajectory, at least one segment of discontinuity comprising a lateral discontinuity, determining a required distance corresponding to a minimum flight distance between the two segments bordering the discontinuity segment and integrating each required distance into the reference profile.
This method further comprises a step of determining, on the basis of the reference profile, vertical predictions relating to a vertical trajectory of the aircraft and a step of determining, on the basis of the vertical predictions, a resulting lateral trajectory comprising, for each discontinuity segment, determining a substitution segment connecting the two corresponding bordering segments in a continuous manner.

Abstract: Methods and devices for optimizing the climb of an aircraft or drone are provided. After an optimal continuous climb strategy has been determined, a lateral path is determined, in particular in terms of speeds and turn radii, based on vertical predictions computed in the previous step. Subsequently, computation results are displayed on one or more human-machine interfaces and the climb strategy is actually flown. Embodiments describe the use of altitude and speed constraints and/or settings in respect of speed and/or thrust and/or level-flight avoidance and/or gradient-variation minimization, and iteratively fitting parameters in order to make the profile of the current path coincide with the constrained profile in real time depending on the selected flight dynamics (e.g. energy sharing, constraint on climb gradient, constraint on the vertical climb rate). System (e.g. FMS) and software aspects are described.
