Abstract

Operating method for a system for airborne wind energy production, said system comprising a ground station, an airworthy glider with an airfoil, and a tether for connecting said glider with said ground station, said system being constructed and arranged for airborne wind energy production using lift generated by said airfoil exposed to wind, wherein a first operating phase of increasing free length of tether including flying said glider away from said ground station is repeatedly alternated with a second operating phase of decreasing free length of tether including flying said glider towards said ground station. The operating method according to the invention is characterized in that wind conditions are monitored, wherein at wind conditions below a predetermined minimum condition, said glider is pulled towards said ground station via said tether during at least a part of said second operating phase, thereby increasing velocity of said glider, wherein additional velocity is used to raise altitude of said glider during the following second operating phase.
