Initial flight tests of the Aviation Partners Spiroid concept on a GII reportedly reduced cruise fuel consumption by more than 10%.

Aviation Partners plans to fly its second-generation spiroid winglets on a company Dassault Falcon 50 in the third quarter. The flight is part of the $2 million earmark the company received last year to further investigate the novel devices, in part to analyse the potential for reducing aircraft separation distances.
API founder and president Joe Clark says the new spiroids, now in design, are likely to eliminate wingtip vortices in the near field region, although the effects in the far-field, roughly 4.6-5.6km (2.5-3nm) behind the aircraft, will have to be determined by test.
