FIG. 1 is a diagram of an aircraft 100. The aircraft 100 includes a cockpit 102, a cabin 104, a wing 106, and a wing 108. The cockpit 102 includes a system 200 that is operable to dynamically modify an initial trajectory profile of the aircraft 100 during flight in response to identifying an impermissible flight condition. For example, while the aircraft 100 is travelling between a starting point and a destination point, the system 200 can modify the initial trajectory profile (e.g. modify a turn center location) in response to a determination that flight conditions of the aircraft 100 make travelling along the initial trajectory profile “impermissible” according to one or more operational rules associated with the aircraft 100. The system 200 is described in greater detail with respect to FIG. 2.
