SYSTEM AND METHOD TO MODIFY AN AIRCRAFT FLIGHT TRAJECTORY

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.
