    C42 SERIES Pilot Operating Handbook Kinds of operation limitations Aerobatics and manoeuvres with more than 60° bank are prohibited! Daylight VFR conditions only. No flight in icing conditions Do not attempt flight in turbulent conditions or in Winds exceeding 22 kts (40 km/h) and less when it is gusty. Always follow the appropriate regulations for this category of aircraft.
  • Page 22 C42 SERIES Pilot Operating Handbook If the engine has been flooded, close main fuel valve, open the throttle to a half and start the engine. When the engine starts, quickly reduce the throttle to idle. A four-stroke engine requires a fairly long warm up period. Run the engine at 2000 1/min for at least 2 minutes then increase to 2500 1/min - 3000 1/min until the oil temperature is at least 122°F (50°C).

  • Page 23: Flight Operations

    C42 SERIES Pilot Operating Handbook Flight Operations Taxiing The nose wheel steering is conventional and is directly connected to the rudder pedals. Push the right pedal to turn right. Push the left pedal to turn left. Taxiing is simple. The turning radius of the C42 is small. The plane handles cross wind during taxing very well.
  • Page 24 C42 SERIES Pilot Operating Handbook Aircraft with the ROTAX 912 UL S (100 hp) have a greater engine torque which must be countered by a slight right rudder input. The aircraft will take-off at 38 kn (70 km/h). Push the stick slightly forward and increase airspeed to 59 kn (110 km/h) in shallow climb.

  • Page 25: Cruising Flight

    C42 SERIES Pilot Operating Handbook Cruising flight In cruising flight the most economical cruise speeds are between 75 and 91 kn (140 – 170 km/h) – C42CS: 86 – 103 kn (160 – 190 km/h). The required engine performance depends upon aircraft load. Max continuous engine speed is 5500 1/min.

  • Page 26: Stalls

    C42 SERIES Pilot Operating Handbook 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. Stalls In cruising flight configuration (flap position I), the stalling speed is 39 kn (75 km/h).

  • Page 27: Descent And Landing

    C42 SERIES Pilot Operating Handbook Descent and landing Begin with your approach early enough in order to set the correct landing configuration without hurrying. Activate carburettor heat. The electrical fuel pump must be switched on. In order to be able to steeply approach short landing strips, use flap position III (landing).

  • Page 32: Ground Handling

    C42 SERIES Pilot Operating Handbook Ground Handling 5.1 Towing Manual moving of the aircraft is accomplished by using the tail struts upper connections as push points. Since there is no tow bar applicable at the nose gear, you have to press down the tail to raise the nose wheel off the ground. With the nose wheel clear of ground, the aircraft can be simply steered by pivoting it on the main wheels.

  • Page 33: Parking

    Additionally, mount a rope or strap between the engine cowling and propeller spinner and secure to another ground anchor. On IKARUS C42 Series models equipped with a towing device, the towing hook can be used as a third anchorage point.

    C42 SERIES Pilot Operating Handbook 4. Drop procedures After completing the climb to the agreed drop altitude, level off the aircraft and continue horizontal flight at the airspeed of 48 to 59 kn (90 to 110 km/h). For that set the flaps to position II (take-off). Then, the skydiver opens his seat belt, takes up his jump position and signals to the pilot that he is ready to jump.
  • Page 76 C42 SERIES Pilot Operating Handbook Therefore, we recommend to preheat the battery before the starting procedure by spinning of the starter (2-3 times for 2-3 sec.) without switched on magnetos. Once the engine is rotating with a sufficient rpm, the starting procedure can be accomplished as usually.
