2.2.3 ELT REMOTE UNIT LOCATION AND INSTALLATION
The ELT Remote Unit assembly must be mounted in the cockpit where the pilot can
easily reach the switches and see the light.
Note:
The Remote Switch Unit is required by TSO-C126 and TSO C91a, for AK-451-
(AF)(AP) Configurations. It is not optional.
It is strongly recommended that the Remote Unit be located in an area that is part of
the pilots normal instrument scan.
Mark a cutout for the cockpit panel switch with the dimensions shown in Figure 10.
Install the Remote Unit assembly by fitting it into the cutout, using four 4-40 screws
and Nylock nuts.
If the unit is to be mounted in a location that does not have a flush mounting surface
(i.e. beneath the panel glare shield), an angle bracket should be fabricated. See Figure
10.1
TSO-C126/RTCA DO-204 paragraphs 1.3 and 2.2.6.1 state, “A remote control to
operate and monitor the transmitter shall be required if the ELT unit is not readily
accessible from the pilot’s position.”
Note:
For Canadian aircraft installation, a placard displaying the
following warning will be placed near the ELT remote unit:
“FOR AVIATION EMERGENCY USE ONLY.
UNAUTHORIZED OPERATION PROHIBITED.”
