When descending, reduce the throttle as normal and when necessary, change the propeller
pitch to full-FINE. (For example, when descending from the overhead to circuit height).
Approach
Keep full-FINE selected when landing to be ready for a possible go around.
Engine shutdown
The engine should be in full-FINE for shutdown.
9-1.4.3 Functional Check VPP
NOTE
Functional check of the variable pitch propeller must be executed during
engine run-up (see 4.7)
Engine RPM: 4000 – Adjust variable pitch propeller in direction ‘COARSE’ until engine RPM
decreases significantly. Afterwards adjust back into ‘FINE’ end position (status indicator
FINE steady on); RPM must increase again up to 4000.
CAUTION
Respect power plant limitations and instrument markings (see 2.6) during
functional check – monitor MAP gauge!
