Manual propeller control
switch is a toggle button, located
separately from the propeller controller unit on the instrument
panel. This switch allows:
o
Direct control of the propeller pitch when manual mode
(MAN) is selected with the automatic/manual selector
switch.
o
Moving the switch up moves the propeller in the fine
direction. The fine indicator light should be illuminated
orange during this operation.
o
Moving the switch down moves the propeller in the coarse
direction. The coarse indicator light should be illuminated
orange in this operation.
o
With the automatic/manual switch set to AUTO, and the
propeller control selector knob selected to HOLD, the
switch (manual propeller control) is used to set a pilot
selected propeller governing speed.
Actuate the switch to change the propeller pitch in
the direction desired. When the desired rpm is
reached, release the switch. The propeller/engine will
be governed to that speed.
Set the desired power with the throttle.
NOTE
When power is initially applied to the propeller controller, the speed
setting at which the HOLD mode will govern the propeller is set equal
to the pre-set CRUISE mode governing speed, until altered by pilot
selection.
