Abstract: A method is provided for monitoring compliance with air traffic control (ATC) instructions by an air crew of an aircraft. First, voice and text ATC commands are received by an ATC instruction moderator support system (AIMSS) located on board the aircraft. The voice and text ATC commands are converted into a data format by the AIMSS. The ATC commands are used to determine an expected aircraft state while a current aircraft state is determined by the aircraft sensors. The current aircraft state is compared with the expected state and determined if it is in compliance. If the current state is in non-compliance, it is determined if the non-compliance is allowable and it is then classified as either no action or incorrect action by the aircrew. Finally, an alert of the noncompliance is generated with the AIMSS.
