-
When the ELT is connected to its system in the aircraft and the G-switch is not triggered, but a signal must be transmitted (aircraft out of operation, injured passengers/crew members).
-
When the ELT is conected to its system in the aircraft and you do a self-test (BITE).
-
When the ELT is disconnected from its system, removed from the aircraft and used in portable mode.
Accidental operation occurs:
-
When the ELT is connected to its system in the aircraft, and the G-switch starts transmission without a real emergency (hard landing).
(b) Controls and Indications
The RED indicator and buzzer operate when the ELT operates, or to indicate the BITE test result. When the ELT operates:
-
The RED indicator flashes two times per second during 121,5 MHz
-243 MHz transmission and one long flash during 406 MHz transmission.
-
The buzzer sounds two beeps per second during 121,5 MHz - 243 MHz transmission and is silent during 406 MHz transmission.
The ON/OFF/ARM switch has these functions:
Set to the ON position for manual operation of the ELT. When you set the ON/OFF/ARM switch to the ON position, the BITE test operates automatically before transmission starts.
Set to the OFF position:
-
When the ELT is connected to its system in the aircraft and requires maintenance, or is parked for a long time.
-
When the ELT is disconnected from its system and removed from the aircraft.
-To stop transmission.
Set to the ARM position for automatic operation of the ELT. When you set the ON/OFF/ARM switch to the ARM position from the OFF position the BITE test operates automatically.
**ON A/C 155-199, 211-228, 301-302,
(2) Adapter cable (141MX) and Programming-dongle connector (110MX-A) (Ref. Fig. 006)
The programming-dongle programs the ELT with the correct aircraft identification and country code. You connect the programming-dongle to the RCP connector on the ELT, and set the ELT ON/OFF/ARM switch to the ARM position. The ELT memory is automatically updated with the data stored in the programming-dongle memory.
**ON A/C 151-199, 211-228, 301-302,
(3) RCP (111MX)
(Ref. Fig. 007)
The RCP operates the ELT from a different location in the aircraft, and is connected to the RCP connector on the ELT. The RCP only operates when the ELT ON/OFF/ARM switch is set to the ARM position. The RCP controls and indication have these functions:
The ON-ARMED-TEST/RESET switch:
-
Is set to the ARMED position for automatic operation of the ELT. The switch is kept in the ARMED position by a stop, which is part of the switch assembly.
-
Is set to the ON position for manual operation of the ELT. You must pull the switch to clear the stop, and then set it to the ON position.
-
Is set to the TEST/RESET position to stop accidental operation, or to do a BITE test. The switch goes back automatically to the ARMED position after you have set it to the TEST/RESET position.
The ON/TEST indicator comes on when the ELT operates, or to indicate the BITE test result. When the ELT operates the ON/TEST indicator:
-Flashes two times per second during 121.5 MHz - 243 MHz transmission
-And, one long flash during 406 MHz transmission.
