5. UTILIZATION OF THE ELT ADT 406² AF / AP (Ref. Fig. 8)
CAUTION : IN THE EVENT OF UNTIMELY BEACON ACTIVATION, SHUTDOWN THE BEACON AND
INFORM THE CLOSEST SEARCH AND RESCUE (SAR) OR AIRPORT CONTROL TOWER
IMMEDIATELY.
The ELT ADT 406² can be activated in two modes :
– automatic when the acceleration sensor is triggered,
– manual.
A. Automatic activation
The acceleration sensor has detected an impact sufficient to trigger it. The indicator light (8) and the aural
indicator indicate beacon activation.
Otherwise do not do anything and leave the beacon in operation until the rescue team arrives.
Upon automatic activation the ELT enter directly in a waiting condition for about 30s (self test is not
performed). This state is displayed by a 2s slow rate blinking on indicator light (8) 1.75s ON, 0.25s OFF.
WARNING :
In case of false activation the operator shall shut down the ELT as described in C. After
this delay the ELT will transmit actual distress signals on the three availables distress frequencies.
B. Manual activation
There are two cases in which a distress signal may be triggered manually :
– the acceleration sensor (G.switch) has not been triggered but a distress signal must be sent (injured
passengers, aircraft out of operation ...),
– the aircraft is on the ground and must be evacuated.
(1)First case, from the Remote Control
Raise the safety cover (guard) on the remote control unit and place the switch in the ON position (lever
upwards).
An automatic self-test sequence is performed (see §D Beacon Self Test).
Then the indicator light (8) and the aural indicator indicate beacon activation. This signal is permanently
displayed on the Remote Control LED.
Do not do anything and leave the beacon in operation until the rescue team arrives.
After about 30s of waiting condition, the beacon will transmit the three actual distress frequencies 121.5-
243-406 MHz.
(2)Second case, from the beacon
Place the beacon switch (9) in the ON position (pull and slide).
An automatic self-test sequence is performed (see §D Beacon Self Test).
