The lever used to control power
by
in-
troducing fuel-air mixture into the intake
passages of the engine. Settings are
reflected by readings
on
the manifold
pressure gage.
This lever requests the governor to
maintain rpm at a selected value and, in
the maximum decrease rpm position,
feathers the propeller.
This lever is used to set fuel flow in all
modes of operation and cuts off fuel
completely for engine shutdown.
Indicates the rotational speed
of
the en-
gine/propeller in revolutions per minute
(rpm).
Regulates the rpm
of
the engine/propel-
ler by increasing or decreasing the pro-
peller pitch through a pitch change
mechanism in the propeller hub.
An instrument that measures the abso-
lute pressure in the intake manifold
of
an engine, expressed
in
inches of mer-
cury (in. Hg).
The Exhaust Gas Temperature Indi-
cator is used to identify the lean and
best-power fuel flow mixtures for vari-
ous power settings during cruise.
