- two equal sized squares (the ones in the middle of the figure)
- keeping the kites in the given positions
- even speed during the figure
Call IN when the two kites fly horizontally, one directly above the other. The Kite 1 flies with the leading edge in the flying direction, Kite 2 flies sideways. At every corner Kite 1 turns 90°, keeping the leading edge in the flying direction. Kite 2 will be kept in the same attitude for the whole figure. The timing of the turns should be such that both kites fly at the same time vertically in the first square, and horizontally in the second. The size of the squares should be about 20%. Call OUT when, on the last stretch, Kite 1 has travelled at least 10% horizontally.
