NOTICE

CESSNA SECTION 7
MODEL 208B G1000 AIRPLANE AND SYSTEMS DESCRIPTION
EMERGENCY POWER LEVER (Continued)
Operation of the EMERGENCY POWER Lever is prohibited with the
primary power lever out of the IDLE position. The EMERGENCY
POWER Lever overrides normal fuel control functions and results in the
direct operation of the fuel metering valve. The EMERGENCY POWER
Lever will override the automatic fuel governing and engine
acceleration scheduling controlled during normal operation by the
primary power lever.
CAUTION
Inappropriate use of the EMERGENCY POWER Lever
may adversely affect engine operation and durability.
Use of the EMERGENCY POWER Lever during normal
operation of the power lever may result in engine
surges, or exceeding the ITT, NG, and torque limits.
PROPELLER CONTROL LEVER
The PROP RPM Lever is connected through linkage to the propeller
governor mounted on top of the front section of the engine, and
controls propeller governor settings from the maximum RPM position to
full feather. The PROP RPM Lever has MAX, MIN, and FEATHER
positions. The MAX position is used when high RPM is desired and
governs the propeller speed at 1900 RPM. PROP RPM Lever settings
from the MAX position to MIN permit the pilot to select the desired
engine RPM for cruise. The FEATHER position is used during normal
engine shutdown to stop rotation of the power turbine and front section
of the engine. Since lubrication is not available after the gas generator
section of the engine has shut down, rotation of the forward section of
the engine is not desirable. Also, feathering the propeller when the
engine is shut down minimizes propeller windmilling during windy
conditions. A mechanical stop in the lever slot requires that the PROP
RPM Lever be moved to the left to clear the stop before it can be
moved into or out of the FEATHER position.
FUEL CONDITION LEVER
The FUEL CONDITION Lever is connected through linkage to a
combined lever and stop mechanism on the fuel control unit. The lever
and stop also function as an idle stop for the fuel control unit rod. The
FUEL CONDITION Lever controls the minimum RPM of the gas
generator turbine (N g) when the power lever is in the IDLE position.
The FUEL CONDITION Lever has CUTOFF, LOW IDLE, and HIGH
IDLE positions. The CUTOFF position shuts off all fuel to the engine
fuel nozzles. LOW IDLE positions the control rod stop to provide an
RPM of 52% N g. HIGH IDLE positions the control rod stop to provide an
RPM of 65% N g .
