ENGINE COOLING
The down-draft engine cooling system provides ground and
inflight power plant cooling. Engine baffling directs
air
over
and around the cylinders and out the cowl flap openings.
Cowl flap doors allow proper
air
flow on the ground and
during low- speed high-power climb. Pulling the cowl flap
control opens the cowl flaps.
VACUUM SYSTEM
An engine- driven vacuum pump supplies suction for the vac-
uum-operatedgyroscopic flight instruments, the retractable
step, and the Mooney Positive Control system. Air entering
the vacuum- powered instruments
is
filtered; hence, sluggish
~
or erratic operation of vacuum-driven instruments may in-
dicate that
a
clogged vacuum filter element
is
preventing
adequate air intake. The
HI
or
LO
indicator light above the
artificial horizon will glow if vacuum
is
above or below
limits.
INSTRUMENTS
FLIGHT INSTRUMENTS
All primary flight instruments are grouped on the floating
shock-mounted flight panel directly in front of the pilot's
seat. The basic gyro flight references are the artificial
horizon, the directional gyro, the vertical speed indicator,
and the turn coordinator. Standard flight instrumentation
also includes the airspeed indicator and the altimeter.
The
flap-position indicator is on the
aft
end of the nose wheel
well.
A standard eight-day clock is mounted in the pilot's control
wheel. The magnetic compass
is
mounted on the windshield
post above the instrument panel. The outside
air
temper-
ature gage with probe is installed through the windshield.
