Question

No person may use an ATC transponder unless it has been tested and inspected within at least the preceding ________.

1) 24 hours
2) 48 hours
3) 72 hours
4) 96 hours

Answer 1

An ATC transponder must be tested and inspected every 24 calendar months to comply with aviation regulations. This ensures accurate communication with air traffic controllers for maintaining aircraft separation.

Step-by-step explanation:

The correct answer to the question about the required interval for testing and inspecting an ATC (Air Traffic Control) transponder is that it should be done every 24 calendar months. This requirement is mandated by aviation regulations for most aircraft that will operate within controlled airspace under Instrument Flight Rules (IFR) or Visual Flight Rules (VFR). The rule states that no person may use an ATC transponder unless it has been tested and inspected within at least the preceding 24 calendar months. Satisfying this condition helps ensure that the transponder provides accurate information to air traffic controllers so they can maintain proper aircraft separation.
