Here is my AOA/AOS gauge from a different angle. From here, you can clearly see both arrows reading the relative airflow (wind) at the same time. The rod is at the same angle as the wing (cord) and is pointing the same direction as the airplane's nose. You'll see when I use left and right aileron (no rudder input) we get quite a pronounced adverse yaw. You'll also see a stall where the AOA reading drops into the red. At the end, you'll see the landing where I'm lined up with the runway and you can see the relative wind (crosswind) coming from the right. At the last moment, a crosswind gust pushes the plane to the right before touchdown.

This indicator can be useful for new pilots and others to directly see and understand their AOA and sideslip angle based on the relative wind. I believe it may even be helpful in reduce the number of stall/spin accidents.

Very nice. This indicator would definitely show the greater adverse yaw of the wing wagger vs. the tail wagger. Maybe dynamic proactive rudder should be called verse yaw or even stabilized yaw.

Yes. Something else it shows is the difference between starting a turn with aileron vs rudder. A turn initiated with aileron will always move the arrow and show some adverse yaw. Whereas a turn initiated with rudder will be coordinated with the arrow consistently pointing into the relative airflow.

Something else that's very interesting is reading ground effect with the arrow AOA gauge. And yes, the stall/spin video is coming up .

Here is a link to the other video I posted. It shows the gauge as viewed from the cockpit.

So what's the idea to prevent accidents? Film this and use it for training post flight? I like the idea of that, but i can't imagine looking out at that device while in actual flight. Maybe that's my hard headedness showing itself again.

Ir needs to be mounted where the light bar goes.
