Powerplant
Control:
1)
Power
levers;
2)
Speed
levers.
POWER
(THROTTLE)
LEVER
Two
power
levers
operate
in
a
quadrant
on
the
center
pedestal
which
is
marked
“FLT
IDLE”,
“GROUND
IDLE,”
and
“REVERSE.”
The
power
lever
connects
to
the
propeller
pitch
control
and
the
fuel
control
unit.
When
the
power
lever
is
between
FLT
IDLE
and
REVERSE,
any
movement
positions
the
propeller
pitch
control
to
provide
a
blade
angle
proportional
to
the
power
required.
When
the
power
levers
is
positioned
forward
of
the
FLT
IDLE,
propeller
pitch
control
is
provided
by
the
speed
levers.
The
power
lever
can
move
freely
between
HIGH
(full
forward)
and
FLT
IDLE
positions.
It
is
not
possible
to
move
aft
of
FLT
IDLE
while
the
aircraft
is
in
the
air.
SPEED
(RPM)
LEVER
Two
speed
levers
operate
in
a
quadrant
on
the
center
pedestal
which
is
marked
“RPM
HIGH”
(forward)
and
“LOW”
(aft).
The
speed
lever
connects
to
the
propeller
governor
and
to
the
underspeed
governor
in
the
fuel
control
unit.
NOTE
In
the
real
aircraft
there
is
a
detent
to
prevent
accidental
movement
aft
of
FLT
IDLE.
The
power
lever
has
to
be
lifted
before
it
can
move
aft.
In
this
case
we
decided
to
restrict
movement
below
FLT
IDLE
while
the
aircraft
is
in
the
air.
