BLR Aerospace of Everett, Wash., received an STC for winglets on the King Air 300. According to BLR, winglets increase cruise speed by five to eight knots, reduce fuel consumption by 3.5 percent and increase rate of climb by 300 fpm. Meanwhile, Sierra Industries of Uvalde, Texas, is developing winglets for the Citation 500 and 560 series. The company says winglets will reduce drag, minimize turbulence and counteract wingtip vortices.
