EMERGENCY LOCATOR TRANSMITTER (ELT)
ELT 96 MODEL (OR ELT 97 MODEL)
The ELT 96 Model (or ELT 97 Model), when activated, transmits a
radio signal on frequencies of 121.5 MHz, 243.0 MHz and 406.0 MHz,
to facilitate airplane location during search and rescue operations.
The system comprises a transmitter, which also can be used in a
portable mode, 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,
provided the portable mode is not removed for ground operation.
Manual activation may be performed either through the ELT front panel
switch or remote switch in cockpit, in both cases setting the switch to
MAN position.
Automatic activation occurs when the ELT switch and the remote
control switch are set to AUTO position and airplane suffers a
deceleration as a function of acceleration/time conditions.
In both cases (manual and automatic activation) the pilot may
deactivate the ELT, performing the AUTO TEST/RESET function.
PORTABLE MODE OPERATION
To operate the ELT 96 or the ELT 97 in portable mode, perform the
following procedures:
− Release the quick-opening fireproof fasteners to remove the ELT
from its compartment.
− Disconnect the fixed antenna coaxial plug from the ANT connector.
− Release the auxiliary antenna from its attaching clips and connect it
to the ANT connector.
− Set the switch to MAN/RESET position.
− Hold or install the ELT vertically, preferably in a cleared area and as
high as possible.
NOTE: When using in temperatures below freezing, keep ELT inside
your jacket with antenna outside for longest operations life.
