BLR Aerospace (BLR) is working with the Federal Aviation Administration (FAA) to amend its Supplemental Type Certificate (STC) that will expand the approved performance envelope for King Air 90s equipped with BLR Winglet Systems. FAA approval was expected by the end of June.
The STC, known as the Ultimate Performance Package™ (UPP), will enable King Air 90 operators to take full advantage of increased gross weight performance improvements, which are significant, with installation of BLR Winglets.
- Up to 30 percent reduction in runway length requirements
- Max takeoff weight increase from 10,100 lbs or 9,650 lbs (depending on aircraft serial number) to 10,500 lbs
- Max landing weight increase from 9,650 lbs or 9,168 lbs (depending on aircraft serial number) to 9,860 lbs
The UPP will be available as an upgrade to King Air 90 operators already flying with BLR Winglets. Operators purchasing Winglets and the Whisper Prop® propeller system will receive the expanded performance STC at no additional cost.
BLR states that it’s been clearly demonstrated that installation of BLR Winglets improves aerodynamic performance for King Airs and translates into bottom-line productivity improvements. And that UPP will provide access to more runways, provide a significant increase in useful load, increase the margin of safety, and improve virtually every aspect of King Air 90 flight.
The BLR Winglet System adds lightweight, composite winglets and a small wing span extension, reducing drag and improving low-speed handling. This translates into fuel savings or increased climb and cruise speeds and high altitude stability, as well as lower takeoff speeds. Whisper Prop is a five-blade, carbon fiber propeller with natural composite core for superior noise and vibration reduction. Whisper Prop is certified for installation on multiple King Air models.
