Sorry Bill not knocking your suggestion which is technically
sound but, ASI,Altimeter, 2 varios, turn and slip,
AH, compass, FLARM, transponder, radio, ELT, GPS, Palm
Top, Anti collision strobe, AoA meter, logger, data
link and batteries to power the above. I need a bigger
glider or perhaps dispense with the pilot :-)

I suspect that surface ports on the top and bottom
of the nose will also
only work at zero slip/skid angle. Marc

Why would that be?

If both top and bottom ports are on the center line
they should be equally
influenced by slip/skid induced crossflow. You'd just
be measuring the
pressure difference between the ports not the absolute
pressure.

BTW, the guys at Black Forrest with pitch strings report
they give advanced
warning of lift so zooms can start a few seconds sooner.
An electronic AOA
indicator should do the same. Seems an AOA indicator
is both a safety
device and a performance boon.
