BLR Aerospace Earns EASA Approval for King Air Winglets

The performance improvements are a direct result of an increase in effective wingspan and associated increase in aspect ratio combined with the beneficial impact of the winglet acting as a physical pressure barrier, conserving valuable lift.


Everett, WA, May 8, 2008 — An amended STC will enable European operators of King Air 200GTs to modify their aircraft with performance-enhancing Winglet Systems. The FAA granted an STC amendment to BLR Aerospace in April, and EASA approval was granted this week.

EASA has already approved certification of the King Air 200 and 300 Winglet Systems. The King Air 200GT incorporates the PT6A-52 engine for increased thermal dynamic power. Winglets are expected to be even more effective on the faster- and higher-flying GTs.

The performance improvements are a direct result of an increase in effective wingspan and associated increase in aspect ratio combined with the beneficial impact of the winglet acting as a physical pressure barrier, conserving valuable lift.

Operators of Winglet-equipped aircraft realize increased cruise speed (3-6 knots) or reduced fuel consumption (3.5 percent less burn), and increased vertical rate of climb (250-400 fpm). Additional benefits include reduced drag, and improved handling qualities. It all adds up to a measurable return on investment for operators, according to Dave Marone, vice president, Sales/Marketing.

European operators who are interested in Winglets may work with dealers in France, Germany, or Sweden.
