KLR-10 Lift Reserve Indicator (AOA)


The KLR 10 Lift Reserve Indicator provides at-a-glance awareness and audible cues of remaining lift in an easy-to-install, easy-to-read device that’s ready for your experimental aircraft. Mounted on the glare shield, the KLR 10 is right at eye level where you need it and provides continuous AOA awareness when scanning for traffic or monitoring the runway environment on approach.

Facts on the Fly:

  • Angle of Attack (AOA) and airspeed mismanagement account for the majority of preventable loss of control accidents in the pattern and on approach
  • The KLR 10 Lift Reserve Indicator will warn you of low lift margin well in advance of the aerodynamic stall 
  • The KLR 10 improves operational safety by increasing pilot awareness of remaining lift during phases of flight with high angles of attack such as takeoff and landing


Better Angle of Attack. Better Safety All Around.

Did you know that an aircraft will stall at the same Angle of Attack, whereas indicated airspeed will vary? Having an onboard sensor that measures AOA increases safety, particularly in high-AOA, low-speed flight regimes such as landing or maximum performance climbs. The KLR 10 is designed to provide you with clear indication to the wing’s available lift reserve. It alerts you with visual and audible cues well in advance of traditional stall warning systems. So you takeoff safely. You land safely. And you enjoy your flight.


The KLR 10 Key Features

  • Easy installation, replaces an existing wing inspection plate, no need to drill holes in the wing
  • Includes an intuitive, compact 2" indicator which can be mounted in the pilot’s primary field of vision
  • Compelling aural and visual alerts of high AoA allow for timely corrective action
  • Enhanced awareness of lift reserve in all phases of flight provides guidance for more stable approaches and smoother landings.
  • Meets ASTM F3011-13 specification
  • FAA approved for installation in certified aircraft per FAA memorandum number AIR100-14-110-PM01
