Sometimes the simpler the better. At least that’s the philosophy James Weibe has always seemed to follow. He’s definitely embraced that approach with the new visual angle of attack (AoA) indicator. No electronics. No special pitot tube.
The Radiant AoA is a simple vane-style pointer you mount to the wing nearest you—well, because you want to see it. According to Radiant, “Our new Visual AOA provides direct visual feedback of the aircraft’s Angle Of Attack. Any pitch change or power change is immediately reflected in the indication. It is designed to mount on the leading edge of an experimental aircraft. It is available with a generic mount for the leading edge of aircraft. A top side mount for Sonex (low wing) aircraft is also available.” The instrument is easily removable to prevent skewering your next Young Eagles ride. (Mom says thanks.)
Weibe includes a demo video for your consideration. “When viewed in flight, the responsiveness to pitch change is immediate, and the vane position precisely shows the changes in airflow and AOA. The best example of this is a 30 second demo clip. In the video, James manipulates the pitch of the aircraft, thus causing the AOA vane to show the effect immediately and precisely.”
