Dear subscribers,
Based on the discussions on this list I am putting an AOA indicator in.
I am putting it in the right wing outside of the fuel tank.
The unit calculates the angle of attack taking the pressure from the top
of the wing, the bottom of the wing, the static pressure and ram air
pressure.
You are required to make a hole in the top and bottom of the wing. The
holes are supposed to have the same % of cord dimension from the leading
edge (see attached sketch).
Question: is someone able to provide a procedure to determine these two
points? How accurate does that have to be?
My idea was: guess and mark the leading edge, take the half dimension of
the thickness of the tailing side. Roll the wing that I get a horizontal
plane through these two points by using a water level. Take a led on a
string and mark top and bottom surface of the wing (see sketch).
Thanks for your help
Ralf
