Throttle IDLE Note: - If only 2000 RPM is reached with full power the propeller is at CRUISE position and must be set to CLIMB position using the standard procedure. Before Takeoff 0. Engine RUN UP 1. Throttle FREE 2. Airbrakes LOCKED 3. Folding doors LOCKED 4. Emergency jettisoning SECURE 5. Trim NEUTRAL 6. Fuel shutoff valve OPEN 7. Carburetor heat OFF 8. Auxiliary fuel pump ON 9. Engine instruments CHECK 10. Parking brake RELEASED

4 Maximum effective cross wind for take off and landing on wet and dry surfaces is 11 Kts Takeoff and Climbing 1. Directional Control MAINTAIN 2. Lift 22 Kts Kts 4. Climb speed (49-60 Kts) CHECK 5.

6 Soaring Flight During unpowered flight, all unnecessary electrical equipment must be switched off to ensure sufficient electrical power to restart the engine. All large electrical current consumers (i.e. position and strobe lights, landing light) are switched off by an automatic relay. On start up the automatic relay switches the electrical consumers back on. 1. Best Glide ratio 62 Kts (IAS) 2. Min sink rate 217 fpm 58 Kts (IAS) 3. Best Thermaling speed 51 Kts (IAS) Engine Shutdown in Flight 1. Throttle IDLE 2. Airspeed (54 Kts) MAINTAIN 3. Cylinder head temperature (150 o C) CHECK 4. Avionic main switch OFF 5. Ignition OFF 6.
