4.3 Cruise
In cruising flight the most economical cruise speeds are between 140 and
170 km/h (75 – 91 kts) for the models C42 (C42A), C42B and C42C, or
between 160 km/h and 190 km/h (86 kts et 102kts) for the C42CS. The
required engine performance depends upon aircraft load at the maximal
continuous engine speed is 5500 rpm.
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.
Example: Typical cruising set up:
Rotax 912 UL Rotax 912 ULS
Engine RPM: 4500 rpm 4500 rpm
Air Speed : 150 km/h (81 kts) 160 km/h (86 kts)
Fuel consumption: 10 -12 l/h 11 - 13 l/h
The maximum speed of must never be exceeded (VNE):
C42 (C42A) : 180 km/h (97 kts)
C42B & C42C : 216 km/h (116 kts)
C42CS : 225 km/h (121 kts)
In a turbulent weather the maximum airspeed is 180 km/h (97 kts) for the
C42 (C42A), C42B and C42C, or 187 km/h (100 kts) for the C42CS.
At the first indication of carburetor icing (rpm drop, stuttering engine
running, increase in fuel consumption as indicated by the flow meter, if
installed) apply carburetor heat and, if possible, fly the aircraft into non-
icing conditions
