Systems and methods for enhanced adoptive validation of ATC clearance requests are provided. In certain implementations, a system comprises a processor executing a controller pilot data link communication application, and at least one source of dynamic information coupled to the processor, wherein the dynamic information comprises data relevant to possible flight paths of an aircraft, the dynamic information being changeable during the flight of the aircraft, wherein the processor processes at least one clearance request that identifies a deviation from the present flight path and validates the at least one clearance request against the dynamic information.
