12. A non-transitory computer readable medium comprising instructions which, when executed, cause a machine to at least: a) calculate a set of motion primitives associated with a first aircraft intent description and a position of an aircraft based on combinations of AIDL instructions, the motion primitives including steady-state conditions or maneuvers to bring an aircraft from one steady-state condition to another; b) represent the motion primitives in AIDL; c) collect information associated with at least one of 1) an aircraft performance model, 2) an environmental model, 3) a flight dynamic model, or 4) the motion primitives; d) initialize a finite state machine based on the collected information, the finite state machine being configured to concatenate motion primitives, wherein states of the finite state machine correspond to steady-state conditions and transitions between the states are defined by maneuvers; e) collect specifications associated with at least one of: 1) flight plan instructions, 2) user preference indications, or 3) operational context indications; f) represent the specifications in a first formal language; g) combine the initialized finite state machine with the specifications represented in the first formal language to obtain a trajectory that satisfies a trajectory specification threshold; h) determine whether the obtained trajectory satisfies the trajectory specification threshold; i) iteratively initialize the finite state machine based on the information until a subsequently determined set of motion primitives satisfies the trajectory specification threshold, the subsequently determined set of motion primitives determined using incrementally modified motion primitives when the obtained trajectory is determined not to satisfy the trajectory specification threshold; and j) produce a representation of a second aircraft intent description of the obtained trajectory represented in AIDL and finalizing the method when the obtained trajectory is determined to satisfy the trajectory specification threshold.
