Posted for Colyn Case <colyncase@earthlink.net>:

while we're on this, I'm interested where others, especially IVP owners, put
their flap switch for the AOA, and what the AOA really does with that
information.   Roughly speaking, it's going to store separate pressure curves
for flaps on and flaps off.   but which would be most conservative:
a) put the switch so that it detects ANY flaps
b) 10 degrees
c) 20 degrees
d) full

My thought was to put it at 12 degrees or so.

[Having worked many airshows with Jim Frantz, the developer of the AOA Pro, the standard answer to your question was to install the flap switch so it actuates with any flap actuation. It simplifies the installation and is the most conservative setting. FWIW.... <Marv>   ]
