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.

Method and system for assisting in the flight management of an aircraft in terms of optimizing the operating costs of said aircraft

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.

Managing the trajectory of an aircraft in case of engine outage

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 Z, 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 FAF, the joining trajectory going from the aircraft to the point FAFand then to the point FF and then to the indicated landing runway without passing through the zone Z. Developments describe the use of a zone Zassociated 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.

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.

Contextual aid to flight management

A method for assisting the navigation of an aircraft comprises: assembly by families of data by a processing unit of predetermined data and acquired data, including meteorological data, the families being predefined, each data value being associated with a time window of validity; formatting the data of the families to associate with each data value a type of graphical representation as text or a scalar, vector, surface, or volume; selection of families of data to be displayed; choice of a display time window for each family of data to be displayed; spatio-temporal discretization of the trajectory; spatio-temporal correlation of the discretized trajectory with each family of data as a function of the time windows of validity, in the display time windows of the family, to extract a sub-assembly from each family of data, by the processing unit; display of the sub-assemblies in a single representation on the same display screen.
