During cruising flight an RPM up to 5500 can be used. Always monitor all
engine parameters during cruise flight, especially when high engine
settings is set. Higher RPM means higher speed, but fuel consumption is
increased significantly at the same time. An RPM setting around 4500 is
usually the best compromise between time and fuel consumption. A
propeller setting is always an important factor. Monitor minimum fuel bulb
indication condition by pushing control button when you expect minimum
fuel quantity (4.1 Litter).
Monitor the atmospheric condition as well
– do not enter turbulence area in
a high speed. Be ready for a sudden weather change during your flight
–
stronger head wind can limit your ability to safely reach planned
destination.
Select carefully the flight path
– avoid flying over large urban areas, large
forests or large water areas as well as over mountains. Landing
possibilities are very limited in case of engine failure or other emergency
over those areas. Always have some suitable landing area within a gliding
range. When it is necessary to cross a large area not suitable for
emergency landing, always climb to the appropriate altitude to reach
suitable landing site once emergency occurs.
