Is there a published measurement for the AOI or distance from rib to orifice of the pitot? New plane, ASI is way off on the low end.
Thanks

Where is/are the statics port(s)? Doesn't matter how accurate the pitot pressure is if the static pressure is wrong.
That's a good question, where are they typically?
Top is pitot and bottom is static. This is the type on our Cub.

Airspeed in a Super Cub doesn't work worth a dam at low speeds. Look where the pitot/static tube is. Notice it's proximity to the flaps which are deployed for landing. Guess what the air does in front of the flaps. Power, pitch and time in the seat.
I fly the PSTOL flaps with a flat attitude where the pitot is in the slip stream but you are sinking as well. My airspeed is probably solid but I know it isn't accurate from glancing at the ground speed and I am more focused on the approach and adjusting my power and pitch.And, FWIW, the ASI on that Cub in the video had a pretty rock solid airspeed indication the whole way down.
All great ideas for you experimental guys. People ask me all the time what airspeed I use for landing. I have no idea, I fly the airplane by feel, pitch and power. I can tell you the Top Cub has a more accurate air speed indicator. They did a lot of testing to find the best place to put the static port.
