Let us consider a crosswind AWES with an aircraft and a long tether moving fast with high tension, generally at a relatively low elevation angle of about 30-35°.
The footprint can be seen as the area of the ground equipment. AWES footprints can be expected to be low.
In the other hand the land use is the delimited zone by the tether as the radius of said area by taking account of all wind directions. If the tether length is 1 km, the land use would be at least 3.14 km², where secondary use would be difficult or not possible due to heavy and highly tensioned aircraft and long tether going fast. It is the reason why the Power to space use ratio should be considered, not the power/kite area or even the power/footprint ratios, but the power/land use ratio (and also the power/space use ratio delimiting the no flight zone).
