When activated, an emergency locator transmitter (ELT) transmits on
A
118.0 and 118.8 MHz.
B
121.5 and 243.0 MHz.✓ Correct Answer
C
123.0 and 119.0 MHz.
Explanation
AIM 6-2-4 says ELTs transmit on 121.5 MHz and 243.0 MHz (and newer ones also on 406 MHz, which satellites monitor, while keeping a 121.5 homing signal). 118.0/118.8 and 123.0/119.0 MHz are ordinary communication frequencies, not emergency beacon frequencies.
