Regulatory Brief -- Emergency Locator Transmitters (ELTs) I did not realize ELT's were required on small GA aircraft.
Quote:
"...When ELTs were mandated in 1973, most GA aircraft were equipped with an ELT that transmits on the 121.5 MHz frequency, the designated international distress frequency. The original ELTs were manufactured to the specifications of an FAA technical standard order (TSO-C91) and have an activation rate of less than 25 percent in actual crashes and a 97 percent false-alarm rate. ..."
