(ELT)
SECTION 1
GENERAL
The ELT consists of a self-contained dual-frequency radio transmit-
I(~rand battery power supply, and is activated by an impact of 5g or more
:lH
may be experienced in a crash landing. The ELT emits an omni-direc-
Iional signal on the international distress frequencies of 121. 5 and 243. 0
MHz. (Some ELT units in export aircraft transmit only on 121. 5 MHz.)
(,eneral aviation and commercial aircraft, the FAA, and CAP monitor
121.5 MHz, and 243. 0 MHz is monitored by the military. Following a
crash landing, the ELT will provide line-of-sight transmission up to 100
nules at 10,000 feet. The duration of ELT transmissions is affected by
ambient temperature. At temperatures of +21° to +54°C (+70° to +130°F),
continuous transmission for 115 hours can be expected; a temperature of
-40°C (-40°F) will shorten the duration to 70 hours.
The ELT is readily identified as a bright orange unit mounted behind
the baggage compartment wall in the tailcone. To gain access to the unit,
remove the baggage compartment wall. The ELT is operated by a control
panel at the forward facing end of the unit (see figure 1).
