Model aircraft should make a straight and level flight of at least 100 meters length centered on the judges’ position.
- Not a straight course (slight corrections are acceptable with a light aircraft)
- Not constant height.
- Not pass over the landing area.
- Not centered on judges’ position.
- Not parallel with the judges’ line.
- Too short a distance (too long is not an error).
- Model aircraft flight path not smooth and steady.
- Too far away, too close, too high, too low.
