Emergency Locator Transmitter
The emergency locator transmitter (ELT) unit is located in the aft tail cone equipment.
The unit is self-contained and battery powered. An indicator light provides a visual
indication of ELT operation. A switch mounted in the unit and a cockpit switch provides
control of the ELT. The ELT cockpit switch panel is located on the instrument panel. An
inertia switch located within the ELT unit automatically activates the ELT unit. Should
an accident occur, the ELT unit would automatically transmit alert tones on the
international distress frequencies of 121.5, 243 and 406 MHz. These frequencies are
monitored by government monitoring stations, military, CAA, FAA and Coast Guard
aircraft. The unit’s internal battery allows transmission of the emergency signal for at
least 50 hours. A flashing indicator light on the ELT unit adjacent to the connectors
indicates ELT unit operation. In the cockpit, a flashing indicator light and an aural
signal also indicate operation. A reset switch, located in the cockpit, is used to stop
ELT transmissions by electronically resetting the G switch, should the ELT be
inadvertently triggered following a hard landing, sudden stop, or other reason. Refer
to the Maintenance Manual of your aircraft for more information on the ELT.
