FAA Ground School Practice Test

What is the maximum interval allowed between transponder inspections?

1. 12 months

2. 18 months

3. 24 months

4. 36 months

The correct answer is: 24 months

The maximum interval allowed between transponder inspections is 24 months. This requirement is established by the Federal Aviation Administration (FAA) to ensure that transponders, which are crucial for aircraft identification and tracking, are functioning properly and are compliant with regulatory standards. Regular inspections help verify that the transponder is transmitting accurate information, which is vital for situational awareness and safety during flight operations. Meeting this 24-month timeline helps maintain the integrity of air traffic control systems and ensures that aviation safety standards are upheld. By adhering to this schedule, operators can avoid potential penalties for non-compliance and ensure their aircraft remain airworthy. Regular inspections also contribute to the overall safety of the aviation system by minimizing the risk of equipment failures that could compromise flight safety.
