FAA Ground School Practice Test

What is the recommended procedure if the aircraft radio fails when landing at a controlled airport?

1. Use visual signals only

2. Observe the traffic flow and look for a light signal

3. Request emergency assistance

4. Attempt to contact ATC using backup radio

The correct answer is: Observe the traffic flow and look for a light signal

When an aircraft's radio fails while approaching to land at a controlled airport, it is essential to adhere to standard operating procedures for such an emergency. Observing the traffic flow and looking for light signals is the recommended procedure because air traffic control (ATC) utilizes visual signals, such as the use of an illuminated light gun, to communicate with pilots who may not be able to receive radio communication. This method allows pilots to visually ascertain how to proceed safely. For instance, a steady green light from the control tower typically indicates that it is safe to land, while a red light may indicate that the aircraft should go around or not land. This procedure emphasizes situational awareness, ensuring that pilots maintain a watchful eye on the surrounding traffic as they seek guidance from ATC through available visual methods. Using visual signals solely may not provide enough context in an impromptu situation, while requesting emergency assistance takes time and may not effectively address immediate needs for landing. Attempting to contact ATC using a backup radio can be a viable option under certain circumstances, but if the primary radio is already inoperative, reliance on visual signals becomes crucial in managing the landing safely.
