Abstract: This aid method for controlling the energy situation of an aircraft includes steps for determining (120) an energy meeting point corresponding to a constraint point, determining (130) a meeting type based on the constraint at the constraint point, determining (140) an energy state of the aircraft relative to a reference altitude profile determined by a flight management system, determining (150) a high-energy joining profile representative of a future path of the aircraft with an energy dissipation strategy, the determination being carried out backwards depending on the type of meeting and the energy state of the aircraft, determining (160) energy deviations relative to the high-energy joining profile, and displaying (170) energy deviations.

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: The present invention relates to a device and a method for assisting aircraft guidance. The method for assisting aircraft guidance is operated by a computation platform for aircraft and comprises steps:



of acquisition of state variables characterizing an aircraft in flight, of environment variables characterizing the environment of the aircraft and of trajectory variables characterizing a reference trajectory of the aircraft;
of calculation of a predicted real trajectory for an upcoming change of direction of the aircraft, based on said state variables, on said environment variables and on said reference trajectory variables;
of determination of conformity to determine if the predicted real trajectory which is calculated conforms or does not conform to the reference trajectory; and
of configuration of a trajectory deviation alert, when the predicted real trajectory does not conform to the reference trajectory.

Abstract: An approach assistance method includes: an initial calculation step for calculating a reference path and the application of a stabilization test for determining whether the reference path makes the landing possible; modification steps implemented in a sequence and applying predefined modification rules and applying the stabilization test after each modification; and a transmitting step including transmitting the reference path to the human pilot, to an autopilot and/or to a traffic management system as soon as the reference path passes the stabilization test.

Abstract: A method implemented by computer for the management of the descent of an aircraft, comprises the steps of: receiving a descent profile; determining a search band comprising a plurality of flight segments of the profile; and selecting a flight segment in the search band. Various selection criteria are described, in particular the consideration of the commands of pitch-up and/or separation with respect to the active segment (anticipation distance). Other developments comprise the fact that the search band is configurable, the consideration of the load factor, modalities of tangent capture (trajectory with no segment crossing), compliance with altitude constraints, the determination of capture parabola modeling the trajectory, as well as the activation of the segment selected as control reference. System aspects and software aspects are described.

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.

Abstract: This method for determining a flight distance over a discontinuity segment comprises the steps of determining an altitude of entry to said trajectory portion and an altitude of exit from said trajectory portion, discretization of an altitude interval delimited by the altitude of entry and the altitude of exit into a plurality of elementary intervals, each elementary interval being defined using an elementary step and, for each elementary interval, determining an elementary slope of the aircraft.
This method further comprises a step of determining the flight distance over the discontinuity segment as a function of a direct distance between the framing segments, the elementary slopes, the elementary steps and the total extent of said trajectory portion.
