HOURMETER-AIRPLANE (OPTIONAL)
An optional hourmeter may be installed to measure airplane accumulated
time. The typical location for the hourmeter is on the right side of
the pedestal, just aft of the SELCAL decoder. It is wired to the right
main gear weight-on-wheels switch, through a switch in the lower
entry door frame. It will measure accumulated time as soon as the
airplane lifts off. The hourmeter receives 28-vdc from a 1-amp HOURMETER
circuit breaker located in the INSTRUMENTS/INDICATIONS
group of the copilot’s circuit breaker panel.
FLIGHT DATA RECORDER (FDR) (OPTIONAL)
The flight data recorder, which may be installed, is a 25-hour Solid-
State Flight Data Recorder (SSFDR) with Underwater Locator Beacon
(ULB) and remote mounted tri-axial accelerometer.
The following CAS illumination is specific to the flight data recorder:
EMERGENCY LOCATOR TRANSMITTER (OPTIONAL)
Dorne & Margolin ELT14
The Dorne & Margolin ELT14 system simultaneously transmits distress
signals on the frequencies of 121.5 and 243.0 MHz. The system will automatically
activate under emergency conditions or may be manually
activated with a cockpit-mounted switch. The system consists of a
transmitter, antenna, remote control and monitor unit, and associated
airplane wiring.
TRANSMITTER AND ANTENNA
The transmitter and antenna are installed in the airplane tail section.
Power for the transmitter is provided by an internal battery pack. The
transmitter incorporates a three-position switch (ARM/OFF/ON). Access
to the transmitter is through an access cover placarded ELT LOCATED
HERE. The antenna is externally mounted and connects to the
transmitter with antenna cable.
Transmitter Switch (ARM/OFF/ON)
Because of its location, this switch is not generally used by the crew. In
the OFF position, the transmitter will not transmit distress signals. This
position is normally used only while servicing the airplane. In the ON
position, distress signals will be transmitted continuously. In the ARM
position, the transmitter will automatically activate if the airplane stops
abruptly. The switch should be in the ARM position for flight.
CAS Color Description
FDR FAIL White The flight data recorder has failed.

REMOTE CONTROL AND MONITOR UNIT
The remote control and monitor unit is installed in the cockpit. Power
for this unit is provided by an internal coin cell. A three-position ON/
ARM/RESET switch provides the remote control for the ELT transmitter.
The ON and ARM positions function the same as described for the
transmitter switch. Once activated, the transmitter may be returned to
an armed status using the RESET function. The ELT can be reset but not
switched off from this control unit.
A red LED, mounted in the end of the switch handle, provides the crew
with the ELT status. The LED indicates ELT status as follows:
OPERATION
To arm the transmitter for automatic activation, the ON/ARM/RESET
switch is placed in the ARM position. If the red LED flashes slowly,
check that the transmitter switch is in the ARM position. If the transmitter
switch is in the ARM position and the LED continues to flash, the
transmitter battery needs replacement. To manually activate the transmitter,
place the ON/ARM/RESET switch to the ON position and
check that the red LED is on continuously. To reset the transmitter, momentarily
place the ON/ARM/RESET switch to RESET and check that
the red LED extinguishes.
LED is: ELT Status:
On continuously The ELT is transmitting.
Flashing slowly (80 times per minute) The ELT transmitter is switched
OFF or the transmitter battery
needs replacement.
Flashing quickly (5 times per second) The remote control/monitor unit
coin cell needs replacement.
Extinguished The ELT is armed.

ARTEX ELT 110-406
The ARTEX ELT 110-406 transmits on 121.5, 243.0 and 406.025 MHz.
The ELT may be manually activated with a cockpit mounted switch or
will automatically activate during an impact. Once activated, the ELT
transmits the standard swept tone on 121.5 and 243.0 MHz. During that
time the 406 MHz transmitter turns on and an encoded digital message
is sent to the satellite. The information contained in the message includes:
