Garmin G36 and 37 GPS/WAAS Antennas
This installation uses one G36 GPS/WAAS antenna and a G37 GPS/WAAS/XM antenna. The
antennas are located in the upper, forward cabin.
Signal Conditioner (2)
Each GEA 71 receives signals from its on-side engine turbine speed sensor, propeller speed
sensor and fuel flow sensors via a Meggitt Signal Conditioner, p/n 85-292-4. This unit converts
the signals from the engine sensors to a signal usable by the GEA 71. These units are installed
behind the instrument panel. Electrical power to the No. 1 Engine Signal Conditioner is
provided from No. 1 Triple Fed Bus and to the No. 2 Engine Signal Conditioner from No. 2
Triple Fed Bus. Both signal conditioners will power-up immediately with external or aircraft
power or battery operation.
Standby Indicators
This STC has two options for standby primary flight indications. The first option is a Mid-
Continent Instruments MD 302 Standby Attitude Module that provides attitude, airspeed, and
altitude indications in one electronic assembly. The second option consists of three separate
mechanical indicators, one each for airspeed, altitude, and attitude.
Mid-Continent Instruments MD 302 Standby Attitude Module (SAM)
Mid-Continent Instruments, part number 6420302-2, is an electronic 3-in-1 standby indicator
assembly instrument with two 2.4" diagonal LCD displays provides standby altitude, airspeed,
and attitude information to the cockpit. It is powered from Standby Instrument Bus and the
emergency standby battery. Lighting Control is connected to the No.1 Dual Fed Bus. It
receives static and pitot pressures from the right-hand pitot/static system. The MD 302 is a
standalone unit and does not interface to any G1000 avionics. The MD302 is installed on the
main instrument panel, between the pilot's PFD and the MFD.
