Abstract: A method for assisting in a flight management of an aircraft calculates a local cost function CF(xi, hj) at various altitudes hj along a planned vertical reference flight trajectory over a discrete set of points P(xi, hj) which forms a two-dimensional grid in which the planned vertical reference flight trajectory varies, the local cost function CF(xi, hj) being calculated locally at each point P(xi, hj) according to aircraft data and environmental data predicted at said local point P(xi, hj). Then, for each point P(xi, hj) of the grid, the method determines a neighbourhood including the point P(xi, hj), and associates a colour K(xi, hj) therewith that is dependent on the value of the local cost function CF(xi, hj) using a predetermined bijective lookup transformation. Next, the method displays the coloured grid formed by the coloured neighbourhoods.

Abstract: A method for managing the trajectory of an aircraft implemented by computer comprises the steps consisting of: receiving the aeroplane performance levels, receiving a flight plan, receiving ground relief data, receiving weather data, determining the coordinates of a safety point according to the aeroplane performance levels, the relief data and the weather data, the safety point making it possible to continue the flight according to a predefined SID landing trajectory in case of outage of one or more engines of the aircraft. Developments are described, notably in computation of the spatial coordinates of the safety point, the management of several safety points and/or of EOSID trajectories, the insertion or the activation of an EOSID trajectory including in the absence of engine outage, the management of the Disarm Point flight plan point. System and software aspects are described.

Abstract: A method implemented by computer for calculating a lateral approach trajectory of an aircraft, comprises the steps of receiving selection of a landing runway; determining a zone Z1, the zone defining trajectory limits to carry out a last turn with a view to landing on the indicated runway; receiving indication of a trajectory point FF defining a point of alignment of the aircraft; determining a joining trajectory bound for a point FAF2, the joining trajectory going from the aircraft to the point FAF2 and then to the point FF and then to the indicated landing runway without passing through the zone Z1. Developments describe the use of a zone Z2 associated with visibility conditions, the calculation of the energy to be dissipated, the use of a predefined descent profile, the emission of alerts and trajectory adaptations by increasing the length of the joining trajectory or use of the airbrakes.

Abstract: A method implemented by computer for the management of the flight of an aircraft comprises the steps of receiving flight directives and flight information associated with these directives; determining a flight context of the aircraft; as a function of the context determined, selecting information from among that associated with the formulation of a directive and/or with a current flight directive and/or with a change of a flight directive; sensorially restoring the selected information. Various developments are described, notably links to documentary resources, the determination of anomalies, the use of predefined logic rules and configuration options. System aspects and software aspects are described.

Abstract: An alert management method implemented by a flight management system for triggering alerts during flight of an aircraft, using a look-up table associating, with each alert, at least one flight parameter and establishing, for each alert and the associated flight parameter, a correspondence between the value of the associated parameter and a plurality of predefined ordered priority levels. The method comprises when an alert is triggered: loading a value of the associated flight parameter, as a function of the state of the aircraft in real time, determining the priority level of the current alert out of the plurality, the priority level being determined by the value and from the look-up table; at regular time intervals and for each active alert, reiterating the preceding steps to determine, for each active alert, an associated priority level that is a function of the state of the aircraft in real time.
