ATTITUDE INDICATOR
The attitude indicator is a self-contained
4-inch, DC-powered instrument which
displays the pitch and roll flight attitude of
the helicopter in relation to the earth's
horizontal plane. A pitch trim knob adjusts
the aircraft symbol vertically. An
inclinometer is built in to the instrument face
to provide yaw trim indication. An ATT FAIL
flag is visible when attitude information is
unreliable.
AIRSPEED INDICATOR
The airspeed indicator is a standard 3-inch
pitot -static instrument that indicates the
airspeed in knots on a scale graduated from
0 to 180 knots.
ALTIMETER (BAROMETRIC)
The altimeter, a standard 3-inch instrument,
indicates the altitude of the helicopter from
minus 1000 feet to plus 27,500 feet. The
barometric pressure scale for setting
reference pressure is shown in inches of
mercury and in millibars.
The magnetic compass is mounted on the central windshield post. A compass card
holder is provided to record the individual helicopter magnetic deviation.
