TRANSMITTER (ELT)
SUPPLEMENT
EMERGENCY LOCATOR
TRANSMITTER (ELT)
SECTION 1
GENERAL
The ELT consists of a self-contained dual-frequency radio transmitter
and battery power supply, and is activated by an impact of 5g or more as
may be experienced in a crash landing. The ELT emits an omni-directional
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.) General
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 miles at 10,000 feet.
The ELT supplied in domestic aircraft transmits on both distress frequen-
cies simultaneously at 75 mw rated power output for 50 continuous hours
in the temperature range of -4°F to +131°F (-20°C to +55°C). The ELT unit in
export aircraft transmits on 121.5 MHz at 25 mw rated power output for 50
continuous hours in the temperature range of -4°F to +131°F (-20°C to
+55°C).
The ELT is readily identified as a bright orange unit mounted on the
right hand side of the baggage compartment wall in the tailcone. To gain
access to the unit, remove the cover. The ELT is operated by a control panel
at the forward facing end of the unit (see figure 1).
