Over the past year, we have been experimenting with an aural AoA
system. I thought an RV-focused training video that illustrates how ON SPEED can be applied during different phases of flight might be of interest to some of the folks in our community:
There are FAQs at the end of the video that answer some of the questions we've had about the system, the most prevalent of which is "is the tone that loud in the cockpit?" (no, it's not). I included a short clip that attempts to convey what the aural system sounds like at ambient cockpit noise level.
We are continuing to experiment with different user configurations, but this video uses the standard aural logic that allows the pilot to hear the entire back side of the drag curve, as I thought that is the best way to convey some of the basic concepts of flying AoA
. I realize the airspeed/AoA debate has been raging since about 1903, but the purpose of this training video is to simply illustrate the concept of flying ON SPEED, and how it's applied as a technique
to help maintain aircraft control and optimize performance. The tactical advantage of an aural system, is that you don't have to look inside the cockpit.
If you've got a properly calibrated AoA
system in your RV, you can achieve much, if not all of the utility demonstrated in the video.
