SECTION I
Introduction and General
This supplement contains basic operating instructions for avionics and
instrumentation which may be installed on the aircraft. As installed
equipment varies with each aircraft, it is the pilot’s responsibility to
become familiar with the operation and function of all installed equipment.
This supplement must be carried in the applicable basic FAA approved
300CB Model 269C-1 Rotorcraft Flight Manual when the rotorcraft is
equipped with any of the instruments or avionics whose operation is
contained herein.
Except as modified by this flight manual supplement, operation in
compliance with the basic approved Rotorcraft Flight Manual is mandatory.

CSP-C1-1A
FAA Approved: 03 Oct 1995 7
Revised: 23 Jul 1999

SECTION II
Limitations
The installation of the equipment listed in this supplement is for VFR
aircraft, only, and does not make the aircraft eligible for flight into IFR or
IMC conditions.
If this aircraft has an installed GPS Navigation System, a placard (Garmin
P/N 161-00024-00, S.A.C. P/N 269A4646-265, or equivalent) stating “GPS
limited to VRF use only” must be installed in clear view, and be easily
readable by the pilot.
If this aircraft has an installed GPS Navigation System, the GPS
manufacturer’s operation manual must be immediately available to the
flight crew.

7.1 FAA Approved: 03 Oct 1995
Revised: 23 Jul 1999

SECTION III
Emergency and Malfunction Procedures
In case of electrical system failure, all unnecessary electrical equipment
should be turned “OFF” to conserve battery power.
Specific emergency procedures for avionics are provided in the individual
operating instructions where applicable.

SECTION IV
Normal Procedures
The pilot’s cyclic stick pistol grip incorporates a three position “trigger”
switch. When the “trigger” switch is pulled to the first detent, the plot’s
microphone is connected to the aircraft intercom (ICS) system. When the
“trigger” switch is pulled through the first detent into the second detent, the
pilot’s microphone is connected to the radio transmitter and the radio
transmitter is “keyed” to transmit. When the “trigger” switch is released, it
returns to the “off” position.
If the aircraft is equipped with dual controls, the “trigger” switch on the
co-pilot’s cyclic stick pistol grip operates the same as the “trigger” switch
on the pilot’s cyclic stick, except the co-pilot “trigger” switch controls the
co-pilot’s microphone.
An optional floor mounted “ICS-XMIT” foot activated switch may be
installed. When the footswitch is depressed on the side placarded “ICS”,
the crewmember with the footswitch, has his microphone connected to the
aircraft intercom system. When the footswitch is depressed on the side
placarded “XMIT”, the crewmember with the footswitch, has his
microphone connected to the radio transmitter and the radio transmitter is
“keyed” to transmit.
The aircraft is provided with headset plug-ins for all crew members. These
plug-ins are hanging cords and are located between the pilot and co-pilot
seats near the top of the seatbacks. The pilot’s plug-in is a plain cord. The
co-pilot plug-in includes a plastic box, (with a clothing clip for attaching to
shirt pocket, etc.) an “ICS” momentary activation switch (for access to the
intercom system) and a coiled cord.
CAUTION
AVIONICS SHOULD BE TURNED ON ONLY
AFTER ENGINE STARTUP. THIS IS A SIMPLE
PRECAUTION WHICH HELPS PROTECT THE
SOLID STATE CIRCUITRY AND EXTENDS THE
OPERATING LIFE OF YOUR AVIONICS EQUIP-
MENT.
