| The 'wind-window' This is a theoretical concept which you must have clear in your mind before using your kite. The wind-window is the region of 3-dimensio-nal space in which your kite will operate, and resembles one quarter of a sphere. IMPORTANT: The power generated by your kite will vary according to which part of the window it is flying in. Minimum power is at the 'zenith'(directly above you),this is called the neutral zone. Maximum power is generated when the kite is located at the centre and towards the bottom of the window, which is in effect dead downwind of you. Never fly your kite in this power zone. On the extreme right and left-hand edges of the window, the power generated is moderate. These are the zones you will mostly fly your kite in while sailing. |
