摘要

A method includes generating a flight plan of an aircraft. The flight plan is based on at least one waypoint and a set of operational rules associated with the aircraft. The method also includes generating an initial trajectory profile based on the at least one waypoint and the set of operational rules. The method further includes identifying an impermissible flight condition associated with the initial trajectory profile. The impermissible flight condition violates at least one operational rule of the set of operational rules. The method further includes generating a modified trajectory profile by modifying at least one aspect of the initial trajectory profile to remove the impermissible flight condition. The modified trajectory profile can be used by a pilot to fly the aircraft, the modified trajectory profile can be used by an autopilot system, or the modified trajectory profile can be displayed.

說明書

Referring to FIG. 4, a diagram of another flight plan 230B having a trajectory profile 232B (e.g., a non-continuous trajectory profile) based on an impermissible flight condition is shown. According to one implementation, the flight plan 230B corresponds to the flight plan 230 of FIG. 2. The flight plan 230B includes a first waypoint 234B, a second waypoint 236B, a third waypoint 238B, and a destination 214B. If the aircraft 100 travels according to the trajectory profile 22B, the aircraft 100 is to fly past the first waypoint 234B and turn towards the second waypoint 236B. After flying past the second waypoint 236B, the aircraft 100 is to turn towards the third waypoint 238B. After flying past the third waypoint 238B, the aircraft 100 is to turn towards the destination 214B.
