Angle Of Attack Indicator Enhances Safety And Performance By Providing Visual And Audible Cues Of Angle Of Attack
The FAA has sent a letter of approval to BendixKing allowing the installation of the KLR 10 Lift Reserve Indicator in certified general aviation aircraft. The KLR 10 improves operational safety by increasing pilot awareness of how much lift remains during phases of flight with the highest angles of attack (AoA), such as takeoff, approach and landing, which account for the majority of preventable loss-of-control accidents.
“Airspeed alone is not a reliable parameter to show how much remaining lift a plane has in advance of an aerodynamic stall since this will vary with aircraft weight, angle of bank and other factors,” said Kevin Gould, president, BendixKing. “Because of this, AoA is a concept that has been embraced by both the FAA and the aviation industry. And with the new KLR 10, BendixKing is at the forefront of bringing advanced safety systems to the general aviation cockpit. We developed the KLR 10 to provide pilots full-time, intuitive AoA awareness, where they receive compelling, easy-to-interpret alerts as the wing approaches its critical angle of attack.”
The KLR 10 delivers AoA information through an intuitive, color-coded visual display that represents lift reserve in a compact indicator, with red indicating little lift is left and green indicating there is enough lift for stable flight. As well, the KLR 10 uses audible cues like “Check AoA” and “Caution, too slow” when it is connected through aircraft audio sources. Additional features of the KLR 10 are:
- Low cost and lightweight
- Easy installation, replaces an existing wing inspection plate, no need to drill holes in the wing
- Includes an intuitive, compact two inch indicator located which can be mounted in the pilot’s primary field of vision
- Compelling aural and visual alerts of high AoA help allow for timely corrective action
- Meets ASTM F3011-13 specification
- FAA approved for installation in certified aircraft per FAA memorandum number AIR100-14-110-PM01
AoA has been used by the military and commercial carriers for decades. With the KLR 10, pilots and operators will now have similar AoA awareness technology for general aviation aircraft in an easy-to-install, affordable product.
The KLR 10 has an MSRP of $1,600 and is available for purchase immediately via the BendixKing Dealer Network. BendixKing will be showcasing the KLR 10 and its latest products at all upcoming aviation trade shows including AEA March 13, 2014 in Nashville, TN.
