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

The method 3400 also includes generating, at the processor, an initial trajectory profile based on the at least one waypoint and the set of operational rules, at 3404. For example, referring to FIG. 2, the flight management system 202 generate the initial trajectory profile 232 based on the at least one waypoint and the set of operational rules 222.

The method 3400 also includes identifying, at the processor, an impermissible flight condition associated with the initial trajectory profile, at 3406. The impermissible flight condition violates at least one operational rule of the set of operational rules. For example, referring to FIG. 2, the flight management system 202 identifies an impermissible flight condition associated with the initial trajectory profile 232. The impermissible flight condition violates at least one of the operational rules 224-228.

According to one implementation, the impermissible flight condition is identified based on a flight time associated with the initial trajectory profile exceeding a particular flight time or a flight distance associated with the initial trajectory profile exceeding a particular flight distance. According to another implementation, the impermissible flight condition is identified based on a turn radius of a particular turn within the initial trajectory profile being greater than a threshold radius associated with capturing a hold.
