System Description
The Mid-Continent MD302 Standby Attitude Module (SAM) is installed as part of G1000H
configuration part number 4220650-3.
The MD302 SAM is a self-contained situational awareness instrument that provides four
secondary functions: attitude, altitude, airspeed and slip indication. The central control knob is the
only user interface on the unit located at the middle-right of the unit bezel.
The MD302 SAM contains an internal and field-replaceable Nanophosphate lithium-ion battery,
which recharges during normal flight, contains a heater for low temperature conditions, and
provides a minimum of 1 hour of operation and up to 2.5 hours when new. If aircraft power to the
unit is lost in flight, the unit will immediately begin operating on internal battery power.
Power to the MD302 is provided via the
SAM
(CB175, 1.5 amp) circuit breaker located on the left
side of the circuit breaker panel (Figure 16).
Refer to Figure 4
for the MD302 unit location. Refer to 28-AC-075 Rotorcraft Flight Manual
Supplement for MD302 operation.
