ARTEX C406-N
TRANSMITTER (ELT)
GENERAL
The Artex C406-N Emergency Locator Transmitter (ELT) installation
uses a solid-state 3-frequency transmitter powered by an internal
lithium battery. The navigation function of the C406-N ELT receives
power from the airplane's main battery thru AVIONICS BUS 1. The
C406-N is also equipped with an instrument panel-mounted remote
switch assembly, that includes a red warning light, and an external
antenna mounted on the top of the tailcone. The remote switch
assembly is installed along the upper right side of the instrument panel
and controls ELT operating modes from the flight crew station. When
the remote switch is set to the ARM position, the transmitter is
energized only when the internal G Switch senses longitudinal inertia
forces per TSO-C91a/TSO-C126. When the remote switch is set to the
ON position, the transmitter is immediately energized.
The C406-N transmitter unit is located in the dorsal fin (right side). On
the ELT transmitter unit is a panel containing an ON/OFF Switch and a
transmitter warning light.
The ELT installation uses two different warnings to tell the pilot when
the ELT is energized. The aural warning is an unusual buzzing sound
that is easily heard by the pilot. The visual warning is a flashing red light
directly above the remote switch that shows the pilot that the ELT has
been activated.
When the C406-N is energized, the ELT transmits the standard swept
tone signal on the international VHF frequency of 121.5 MHz and UHF
frequency of 243.0 MHz until battery power is gone. The 121.5 MHz
signal is mainly used to pinpoint the beacon during search and rescue
operations, and is monitored by general aviation, commercial aircraft,
and government agencies.
In addition, for the first 24 hours of the ELT being energized, a 406.028
MHz signal is transmitted at 50 second intervals. This transmission
lasts 440 milliseconds and contains identification data programmed into
the ELT and is received by COSPAS/SARSAT satellites. The
transmitted data may include the Aircraft ID, GPS coordinates, ELT
Serial Number, Country Code, and COSPAS/SARSAT ID.
