5.6 Best rate of climb speed (V
y
)
5.6.1 Climbing
- speed MAX RPM
- airspeed 75 MPH
- engine instruments CHECK
5.7 Cruise
5.7.1 Cruise flight
- put the aircraft into level flight
- engine speed 4000
– 5500 RPM as required
- airspeed 69
– 120 MPH as required
- engine instruments CHECK
- fuel tank levels CHECK
During cruise flight an RPM up to 5500 can be used. Always monitor all engine parameters during cruise
flight, especially when high engine power settings are used. Higher RPM means higher speed, but fuel
consumption is increased at the same time. An RPM setting around 4500 is usually the best compromise
between speed and fuel consumption. Check the operation of the minimum fuel indicator bulb by pushing
the control button when the fuel level is approaching the minimum fuel quantity (1.1 U.S. gallons).
Monitor the atmospheric conditions as well
– do not enter areas of turbulence at speeds above 110 mph.
Be ready for sudden weather changes during your flight
– stronger headwinds can limit your ability to
safely reach your planned destination.
When carburetor icing is possible, activate carburetor heating. The fuel consumption and remaining fuel
on board should be monitored. Always make a comparison between estimated and actual time above any
waypoint.
Take care when selecting 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 an appropriate
altitude to reach a suitable landing site should an emergency occur.
Always monitor the airspace around you to prevent a mid-air collision.
5.8 Approach
5.8.1 Descent
- throttle JUST ABOVE IDLE OR AS REQUIRED
- engine instruments CHECK
- carburetor heating ACTIVATE WHEN NECESSARY
WARNING
During long approaches and when descending from a considerable height, it is
not advisable to reduce the engine throttle control to idle. In such cases the
engine becomes overcooled and a loss of power might occur. When descending,
set the power to just above the idle so that engine instrument readings range
within the limits for normal use.
5.8.2 Downwind
- power 4000
– 5000 RPM
- airspeed 75
– 90 MPH
- engine instruments CHECK
