Date Sep. 30, 1993.The present invention relates to an airplane detection system to surely detect an airplane moving along a runway or a taxiway. The system employs a wheel detection sensor for providing a wheel detected output when emitted electromagnetic waves are blocked by the wheels of the airplane and a fuselage detection sensor for providing a fuselage detected output when receiving the reflection of the emitted electromagnetic waves from the fuselage of the airplane. According to the output signals from both the sensors, the system detects the airplane.
