REFLECTOR: AOA / Pitot tube and electric to the wing tips

[Don Johnston via Reflector]

Tagging on...

The wing wire duct is precut.  I don't think that I've ever heard of wing
cores that weren't cut for wires.  When you drill the holes for the wingtip
lights, you'll see the duct close to the leading edge.

AOA:  The AOA indicators that I've seen have to be calibrated after
installation.  So they will be calibrated to whatever condition you want.
In our case, the canard.
