Methods and systems are provided for generating a route that facilitates navigating a vehicle to a diversion destination while satisfying applicable safety thresholds or other constraints, such as a maximum landing weight. One exemplary method of facilitating an aircraft landing at a diversion airport involves obtaining a current position of the aircraft, identifying a landing threshold influenced by a characteristic of the aircraft, obtaining one or more constraints associating with diverting to the diversion airport, and determining a route from the current position to the diversion airport based at least in part on the landing threshold and the one or more constraints. The route satisfies the constraints and results in a predicted value for the aircraft, e.g., a predicted aircraft landing weight, that satisfies the landing threshold. A graphical representation of the route is displayed on a display device onboard the aircraft.

Methods and systems are provided for presenting contextual weather information with respect to a predetermined route of a vehicle. Routing data for a vehicle is integrated with weather data for an area to generate contextual weather information.

A reference vertical profile comprises a set of vertical constraints, and a method comprises a step of selecting an altitude constraint to be complied with, a step of calculating a vertical-profile prediction making it possible to comply with the constraint, a step of validating the vertical-profile prediction, if the vertical-profile prediction is validated, a step of applying the vertical-profile prediction, otherwise a step of determining the existence of a following altitude constraint to be complied with; if a following altitude constraint exists: a step of selecting a following altitude constraint to be complied with; a return to the step of detecting non-compliance with an altitude constraint; otherwise, a step of applying an exit procedure.

A method for managing a multi-destination flight of an aircraft comprises a first step of constructing an initial flight plan of a mission between an endmost departure point and an endmost arrival point, having a series of temporally ordered waypoints. A second step comprises selecting one or more waypoints from among the waypoints, and transforming the selected waypoint or waypoints into one or more corresponding intermediate touchdown points, each intermediate touchdown point having the same initial coordinates as the corresponding waypoint of which it is the transform, and each intermediate touchdown point comprising a computerized relationship of association with a dedicated intermediate arrival procedure, ready to be activated.

Method, system, and user terminal are disclosed for splicing a flight route splicing m. Various embodiments may includes: obtaining a first flight route and a second flight route of an unmanned aerial vehicle; extracting a flight height of a highest waypoint having a greatest flight height in the first flight route and the second flight route and ground elevations of a series of waypoints between a termination waypoint of the first flight route and a start waypoint of the second flight route; obtaining a flight height of an intermediate flight route; determining the intermediate flight route; and splicing the first flight route and the second flight route according to the intermediate flight route to generate a spliced flight route.

A method comprises computing position information from a global navigation satellite system (GNSS); computing an altitude measurement based on retrieved information from a vertical position sensor; determining a vertical protection level (VPL) associated with the position information; splitting the VPL into an upward VPL component and a downward VPL component; determining a vertical alert limit (VAL) associated with the altitude measurement; and splitting the VAL into an upward VAL component and a downward VAL component. The method optimizes an integrity budget allocation between the upward and downward VPL components. The method then recomputes the upward and downward VPL components given the optimized integrity budget allocation.
