What is the recommended timing for an ELT test?

• A. During the first 5 minutes after the hour
• B. During the last 5 minutes after the hour
• C. At any time with engine running
• D. Only during maintenance weeks

Answer: (A)

Testing an ELT is done in a specific time window—the first five minutes after the hour. This timing helps distinguish a test signal from a real distress call, since monitoring centers and SAR systems expect tests to occur at predictable times and can label them as tests if they’re within that window. Keep the test brief, usually just a short transmission, so you don’t tie up the emergency network or trigger unnecessary responses. The idea is to verify the unit is functioning without causing confusion or false alarms. Testing at a random time, or only during maintenance weeks, isn’t standard practice, and testing while the engine is running doesn’t align with how these checks are normally conducted.
