13.3 Cruising flight
When transitioning to cruise flight, strive for an economical cruise speed.
The required engine performance depends upon aircraft load.
Max continuous engine speed is 5500 1/min.
In order to fly the aircraft comfortably, it should be trimmed to the desired
airspeed with the throttle set for the appropriate rpm for horizontal flight.
Typical cruising flight (approximate values):
ROTAX 912 UL
ROTAX 912 ULS
Engine speed
4800 1/min
4800 1/min
Airspeed
81- 86 kn
92-97 kn
150-160 km/h
170-180 km/h
Fuel flow (approx.)
2.86-3.30 gph
3.30-3.74 gph
13-15 l/h
15-17 l/h
In a turbulent weather, the maximum speed V
B
(see operating limitations)
must be observed.
The maximum permissible speed V
NE
(see operating limitations) must not be
exceeded.
At the first indication of carburettor icing (rpm drop, stuttering engine
running, increase in fuel consumption) apply carburettor and, if possible,
fly the aircraft into non-icing conditions.
13.4 Turning flight
Turns are coordinated using the ailerons and rudders.
With the increase of airspeed, significantly less amount of rudder
deflection is needed.
Banks of 45 degrees or more are not recommended, a banking angle of
more than 60 degrees is prohibited. In steep banks keep the nose and
airspeed under control by means of the rudders and elevator.
