Methods and apparatus are provided for monitoring execution of air traffic control (ATC) conditional clearances for a user aircraft. The method monitors ATC clearances transmitted to all other aircraft across each communication channel from an airport. Every other aircraft is identified and the relevant data each ATC clearance is transcribed. A dependency table is generated for the user aircraft with the relevant data from every other aircraft. The dependency table identifies each relevant clearance that must be completed by all other aircraft before the user aircraft executes a conditional ATC clearance. The status of all relevant dependent ATC clearances is monitored and the user aircraft is informed of its conditional ATC clearance upon completion of the relevant dependent ATC clearances.
