Abstract: A method and system for evaluating the position of landing gear on an aircraft has been developed. A change is detected in audio noise of the aircraft from an enhanced flight audio recording system (EFARS) and compared with a database of audio outputs of the aircraft with the landing gear extended. An increase in vibrations of the aircraft is detected with a flight management system (FMS) and compared to a database of vibrations of the aircraft with the landing gear extended. A decrease in airspeed of the aircraft is detected with the FMS and compared with a database of airspeed of the aircraft with the landing gear extended. The position of the landing gear is determined based on results of comparisons of the change in audio noise, the increase in vibrations and the decrease in airspeed. The position of the landing gear to is then indicated to the pilot.
