It is the reason why I added a fall zone.
And this is yet a very optimistic first assessment. You rightly mention:“The “fall-land area” is much larger than the disk of radius of length of the energy-kite system (AWES). Why? Breakaway wing sets with tethers could fall/drag for tens of kilometers and more”.
But most of all the area of 3000 meters x 1000 meters height that was granted by the Norwegian CAA to Kitemill is irrefutable proof of the land and space use problem and confirms what I am telling for years. The Norwegian CAA unterstands it but not AWE players. And the issue is similar whether for the no-fly zone, and the land area. It’s obvious.
I think it is not possible due to the tethers, particularly for crosswind AWES. It would perhaps be possible for small static AWES flying at a high elevation angle. So It must be admitted that a reserved space is essential, and therefore think of maximizing it, using the Power to space use ratio instead of the power/kite area ratio.
