Extend the ice vanes during ground operation to
minimize foreign object damage (FOD) to the engine.
Taxi speed can be effectively controlled by the use of power
application and the use of the variable pitch propellers in the ground fine
range with the PROP levers retarded to the FEATHER detent.
Brakes - Check.
If brakes have been overhauled, burn in the brakes
by applying near maximum braking (short of
locking) for one or two landings or high speed taxi
runs. After this, check brakes for any tendency to
Flight instruments - Check for normal operation.
Nosewheel steering - Check for no turning
tendency while taxing straight ahead with the
same RPM on both engines, with no braking and
no rudder applied to either side. (This check
must be performed with minimum cross wind.)
Check freedom of movement and ability to turn
aircraft using rudder pedals, engines and
brakes. Note any indication of nosewheel
vibration or shimmy during takeoff or landing.
