The model aircraft approaches in straight and level flight on a line parallel with the judges’ line, and then a one quarter circle turn is made in a direction away from the judges’ line. This is followed by a 360-degree turn in the opposite direction, followed by a 270-degree turn in the first direction, completing the maneuver on the original approach line. The intersection (mid point) of the maneuver shall be on a line that is at right angles to the direction of entry and passes through the center of the judges’ line.
- Entry into first circle not at right angles to original flight path.
- Circles unequal size.
- Circles misshapen.
- Constant height not maintained.
- Intersection not centered on judges’ position.
- Entry and exit paths not on same line.
- Entry and exit paths not parallel with judges’ line.
- Overall size of maneuver not realistic for prototype.
- Model aircraft flight path not smooth and steady.
- Too far away / too close / too high / too low.
