How long can you fly without an ELT?

No person may operate the aircraft more than 90 days after the ELT is initially removed from the aircraft. Aircraft with a maximum payload capacity of more than 18,000 pounds when used in air transportation.

What is ELT frequency?

ELTs of various types were developed as a means of locating downed aircraft. These electronic, battery operated transmitters operate on one of three frequencies. These operating frequencies are 121.5 MHz, 243.0 MHz, and the newer 406 MHz.

When must an ELT be on the aircraft?

Fixed and deployable automatic type transmitters must be attached to the airplane as far aft as practicable. (2) When 50 percent of their useful life (or, for rechargeable batteries, 50 percent of their useful life of charge) has expired, as established by the transmitter manufacturer under its approval.

Unless something has changed, you can fly without an ELT if you have a single seat airplane or if you stay within 50 miles of where the aircraft is based. If you don’t like those limitations, you’re legal if you install a 121.5 ELT.

What is purpose of an ELT?

ELTs are emergency transmitters that are carried aboard most general aviation aircraft in the U.S. In the event of an aircraft accident, these devices are designed to transmit a distress signal on 121.5 and 243.0 MHz frequencies, and for newer ELTs, on 406 MHz.

What is the purpose of ELT?

How is an ELT activated?

ELTs are mounted aft in the airplane, and may be activated upon impact or manually using the remote switch and control panel indicator in the cockpit. Activation of the ELT triggers an audio alert, and 406-MHz ELTs transmit GPS position for search and rescue.

How long will ELT transmit?

An emergency locator transmitter (ELT) is an independent battery powered transmitter activated by the excessive G-forces experienced during a crash. It transmits a digital signal every 50 seconds on a frequency of 406.025 MHz at 5 watts for at least 24 hours.
