The following CAS illumination is specific to the CVR:
The erase function is initiated by pressing the erase button on the CVR
panel. An interlocking device only allows this function to work when
the airplane is on the ground and parking brake is set. When erase function
is complete, a three-second tone is output to the headphone jack.
Voice recorder system power is 28-vdc supplied through a 3-amp CVR
circuit breaker located on the pilot’s circuit breaker panel (INSTRUMENTS/
INDICATIONS group).

CLOCKS
Each instrument panel is equipped with a multi-function chronometer
to display GMT, local time (LT), flight time (FT), and elapsed time (ET).
The SEL button selects what is to be displayed and the CTL button controls
what is being displayed (Figure 5-21). Pressing SEL sequentially
selects GMT, LT, FT or ET for display. FT starts counting when the main
gear weight-on-wheels switches transition to the air mode and stops
counting when they transition back to ground mode. The CTL button
resets FT back to zero when held down for three seconds. ET is started
and reset when the CTL button is pushed momentarily. Depressing the
SEL and CTL buttons simultaneously enters the set mode and GMT or
LT can be set. The CTL button is then pressed to increment the flashing
digit to the desired value. Pressing the SEL button enters that value and
toggles to the next digit to be set.
Power for the chronometers is 28-vdc supplied through a 1-amp L and
R CLOCK circuit breaker located on pilot’s and copilot’s circuit breaker
panels respectively (INSTRUMENT/INDICATIONS group).

HOURMETER-AIRCRAFT (OPTIONAL)
An optional hourmeter may be installed to measure aircraft accumulated
time. The typical location for the hourmeter is on the RH side of the
pedestal, just aft of the SELCAL decoder. It is wired to the right hand
main gear weight-on-wheels switch, through a switch in the lower
entry door frame. It will measure accumulated time as soon as the
aircraft 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
