The model aircraft commences the maneuver in level flight by reducing power on base leg, and then turns onto a higher than normal final approach that is parallel with the judges’ line. As model aircraft enters the turn it starts a Side-slip by the application of opposite rudder to the direction of turn, achieving a yaw of at least 20º off track. A marked loss of height must be apparent while maintaining final approach speed. The aim of the Side-slip, if continued, would be to effect a landing in front of the judges.
Before reaching judges’ position however, the Side-slip is corrected, normal flight is resumed and the model aircraft carries out an overshoot from below 5 meters before climbing away. Purpose of this maneuver is to demonstrate a marked loss of height on final approach without an excessive build up of speed or the use of flap. This maneuver may be nominated by all types of model aircraft.
- Model aircraft does not smoothly enter Sideslip upon turning final approach.
- Model aircraft is not yawed at least 20º off track during Sideslip.
- Rate of Sideslip and descent are not constant.
- There is insufficient height loss.
- Excessive speed is built up during descent.
- Approach track not maintained or not flown parallel with judges’ line.
- The Sideslip is not corrected before passing the judges.
- Overshoot is not below 5 meters.
- Not a smooth transition during return to normal flight and climb out.
- Too far away / too close / too high / too low.
