I do disagree [a bit]. Yes, it does work as advertised. Whether it is "sufficient" depends on what that means. No AOA system is "Sufficient". We did without them for many, many years.
... But a better AOA system - what
RV14_TD meant (
I think) was
Fly On-Speed, not
In Speed), is so much better that you have to experience it to understand. It communicates AOA, using a aural tone signal, in a way that, after experiencing and using it for a very short period of time, can make it an integral part of your constant, unavoidable, hard-to-ignore situation awareness about the state of your aircraft aerodynamic performance.
Among other advantages, it "
almost" eliminates the tendency or temptation to pull on the pole/yoke to solve aircraft maneuvering issues that in many cases result in loss of control and fatal low altitude stall spin accidents. It effectively eliminates the need to monitor indicated airspeed inside the cockpit during critical low-altitude phases of flight like traffic patterns, (overshooting final approach!), circling approaches in low/marginal visibility after breaking out of an overcast, etc. etc. When set up properly, it also allows the pilot to quickly and easily determine, achieve and maintain maximum L/D (minimum drag) AOA in situations where that might be important, again, without monitoring indicated airspeed, independently of gross weight, bank angle, or thrust/power setting.
To get a small taste of this go to their
