2.1. Op er a tion
One of the pri mary fea tures of the
C406-2 se ries ELT’s are their sim plic ity of
op er a tion. As long as the ELT is locked
into its mount ing tray, it will ac ti vate in a
crash. Nei ther the cock pit switch nor the
ELT unit switch can be po si tioned to pre-
vent au to matic ac ti va tion once the unit is
mounted prop erly.
It also is de signed against hu man er ror
and mis use in re gards to au to matic ac ti -
va tion. The unit ac ti vates only when se -
cure-ly mounted in its tray and has pins
5 & 8 jumpered. The ELT can not be ac -
ci dently ac ti vated by drop ping, rough han -
dling or dur ing ship ping.
When the ELT is ac ti vated, the pres ence
of the emer gency swept tone and a flash -
ing front panel light in di cates a nor mally
func tion ing unit. The front panel light must
im me di ately be gin to con tin u ously flash
upon ELT ac ti va tion.
Un der nor mal op er a tion the switch con
-
fig u ra tion on your front panel is the down
po si tion, read ing “ARM”. The switch on
the ELT unit will also be po si tioned down
to read “OFF”. Should an emer gency
arise to the de gree that you want to
man u ally ac ti vate your ELT, re verse ei ther
switch so it is in the up (“ON”) po si tion.
Re mem ber, that as long as the front
panel and ELT switches are in the ARM
/OFF po si tion the ELT will au to mat i cally
ac ti vate on im pact.
If your ELT is ac ti vated ac ci den tally,
you will need to re set it. Do this by mov
-
ing the front panel switch to “ON”, then
im me di ately rock ing it back to “ARM”. You
may also re set the ELT at the unit it self
by po si tion ing the switch on the ELT up
to “ON”, then im me di ately back down to
“OFF”.
2.2. Over all Func tions
Fig ure 2-1 shows the func tional flow for
the ELT. The ELT unit is con sid ered to
be ei ther “AC TIVE” or “IN AC TIVE”. When
“IN AC TIVE”, the unit lies in a state of
rest and per forms no func tions. Taking
the unit from the “IN AC TIVE” to the “AC-
TIVE” state re quires a pos i tive switch
tran si tion from one of three sources:
Panel Mounted Switch
Unit Mounted Switch
G-switch
Upon en ter ing the “AC TIVE” state, the
unit shall meet all the re quire ments as
de scribed herein. To exit the “AC TIVE”
state and en ter the “IN AC TIVE” state, a
“RE SET” con di tion must be en tered. This
may be ac com plished in one of two
ways.
(a) The front panel switch may be tog -
gled from the “ARMED/RE SET” po si tion
to “ON” and then back to “ARMED/RE
-
SET”, or if the switch is al ready in the
“ON” po si tion, it must be placed into the
“ARMED /RE SET” po si tion.
(b) The ELT unit switch may be moved
from the “OFF” po si tion to the “ON” po si
-
tion and then back to the “OFF” po si tion.
If the switch is al ready in the “ON” po si
-
tion, it must be placed into the “OFF”
po si tion.
It should be re mem bered that the ELT
can not be “RE SET” if ei ther the panel
mounted switch or the unit switch is in
the “ON” po si tion.
The pe ri od ic ity of op er a tional checks is
at the op er a tor’s dis cre tion, how ever, a
monthly test is rec om mended. The check
shall only be con ducted dur ing the first
five min utes of any UTC (co or di nated uni
-
ver sal time) hour, and re stricted in du ra -
tion to not more than five sec onds.
