9-1 Variable Pitch Propeller – Woodcomp KW-30
9-1.1 General
A constant speed/variable pitch propeller (VPP) manufactured by Woodcomp is available as
optional equipment to optimize the propeller efficiency, fuel consumption, and noise in all
flight regimes and power settings. This is achieved by changing the propeller pitch.
Read the Woodcomp operation manual!
9-1.2 Limitations
No change to standard aircraft
9-1.3 Emergency Procedures
Proceed according to generic variable pitch propeller procedure provided in SECTION 3 for
the standard aircraft.
9-1.4 Normal Procedures
9-1.4.1 Set Propeller to FINE
In order to set the propeller to FINE for start-up, take-off and approach, press the middle of
the blue propeller control knob mounted on the instrument panel, and push the knob fully to
the panel.
9-1.4.2 Adjust Propeller COARSE
To adjust the propeller pitch to a coarser setting, depress the button in the middle of the
blue propeller knob on the panel, and pull it rearwards. This is a constant speed propeller,
providing the throttle is set to give sufficient power, then the engine rpm will be maintained.
NOTE
As a safety measure, the mechanical end stop in full COARSE position is
chosen to allow a residual climb rate of 1 m/s in standard atmospheric
conditions at sea level with maximum allowed gross mass.
