EMERGENCY LOCATOR TRANSMITTER (ELT)
ELT 110-4 MODEL
The ELT 110-4 Model, when activated, transmits a radio signal on
frequencies of 121.5 and 243.0 MHz, to facilitate airplane location
during search and rescue operations.
The system comprises a transmitter with an ON/OFF switch and an
impact switch installed in the lavatory right ceiling panel, an antenna
located on the top rear and a remote panel located on the cockpit.
ELT may be manually or automatically activated. In both cases a red
light flashes on the cockpit panel to indicate the ELT activation.
Manual activation may be performed when any switch is set to ON
position.
Automatic activation occurs when the transmitter switch is set to OFF
position, the cockpit switch is set to ARM position and the airplane
suffers a deceleration greater than 5 g's.
In both cases (manual and automatic activation) the pilot may
deactivate the ELT, performing the TEST/RESET function.
