(3)ELT ADT 406² AF / AP aircraft components
(a)Remote control unit
The remote control unit integrated in the aircraft cockpit consists of :
– a RESET/TEST pushbutton,
– an ELT ON indicator light,
– a two-position ON/ARMED switch with safety cover (flip guard). The safety cover forces the switch
to ARMED position. This switch must always remain in this position, except in the case of manual
distress triggering.
The beacon is integrated in the aircraft as far aft as possible and so it must be connected to the remote
control unit. This remote control unit enables beacon operation to be forced to ON, to be tested (TEST)
or shutdown and restore in standby or ARMED mode (RESET) in the event of an untimely triggering of
the ELT, from the aircraft cockpit.
(b)External antenna
An external antenna is recommended to be installed on the fuselage of the aircraft to maximize
transmission of the distress signal to the satellites as required by JAR OPS.
The cable length should remain as short as possible in order to keep RF losses as close as possible to
0.5 to 1 dB at each frequencies (121.5/243/406.028 MHz) and to reduce the probability of cable damage
during the crash.
