TAXIING

POWER Lever BETA range can be used during taxi to control taxi
speed and improve brake life. A leaf spring is installed in the control
quadrant which the POWER Lever contacts and provides the pilot with
a noticeable "feel". With the POWER Lever moved to this position in
the BETA range, the propeller is near zero thrust in a static, 52% idle
condition. Besides acting as a zero thrust reference during taxi, this
POWER Lever position (lever against spring) is used after landing to
minimize brake wear. POWER Lever movement further aft of the BETA
range will result in increased engine power and reverse thrust from the
propeller blades.
•
The use of reverse thrust should be minimized,
especially on unprepared surfaces, to minimize
propeller blade erosion and possible damage.
•
Do not leave the POWER Lever in the BETA range
for extended periods (greater than 30 seconds)
when parked with a right crosswind to avoid damage
to the cargo pod.
During low-speed taxi with a strong tailwind, or when
stopped with a strong tailwind, a moderate vibration can
occur as a result of reverse airflow through the propeller
disk with the blades at a positive pitch angle. This vibration
can be significantly reduced by placing the POWER Lever
in the BETA range, or it can be eliminated by turning the
airplane into the wind.
Refer to the Taxiing Diagram figure for additional taxiing instructions.
