How will the wing-span be measured?

Wing span is the projected span, wings level, projected on a horizontal plane, tip to tip. It is usually measured with a simple gage and has to pass through a 28.0 cm gap (parallel edges) without touching. Think of the gage as physically representing two parallel lines spaced 28 cm apart. Glider must pass when the tips are oriented to a plane orthogonal to both lines.
