Abstract: Examples for flight navigation determination are presented herein. An example may involve obtaining a target destination for an aircraft and determining an initial flight path between a current location and the target destination. The flight path may include a series of waypoints for guiding navigation. The example may further involve obtaining terrain information that represents elevations of obstacles along the initial flight path and modifying the initial flight path to generate a revised flight path using the terrain information. The revised flight path may include modifications to the series of waypoints of the initial flight path such that navigation of the revised flight path avoids obstacles positioned along the initial flight path. The obstacles may have an elevation that exceeds an adjustable threshold elevation that depends on the initial flight path. The example may further involve providing the revised flight path to a navigation system of the aircraft.

Abstract: Systems and methods for displaying position sensitive datalink messages on avionics displays are provided. In one embodiment, a flight deck instrument display system for an aircraft comprises: a flight plan display screen that displays a graphical representation of at least a part of an aircraft's planned flight path together with symbology representing a position of the aircraft with respect to the aircraft's planned flight path; wherein the flight plan display screen further displays at least one symbol positioned along the graphical representation of at least a part of the aircraft's planned flight path that indicates a point of applicability for a received uplink datalink message.
