During an ELT test, what audible indication confirms proper operation?

• A. Silent test
• B. One beep
• C. Two beeps
• D. Three beeps within the first five minutes of the hour

Answer: (D)

When testing an ELT, you’re checking that the transmitter actually operates and can broadcast a distress signal. The proper indication is three audible beeps delivered in quick succession, and this should occur within the first five minutes of the hour. That specific pattern confirms the unit is transmitting correctly and that the test is being conducted within the designated window to avoid false alarms and interference with real emergencies. If you hear silence or only one or two beeps, the transmitter may not be functioning properly, or the test wasn’t performed according to the procedure.
