Thanks Wolfgang.  I’d just sent in a correction when yours came in.

You may want to check your numbers.

At 100 Knots you're only going to get about 1/4 psi (0.5" Hg)

Bruce,

Thanks for the link to the pressure switches.  I’m looking at airspeed pressure switch options for possibly toggling in lower trim tab servo speeds at higher air speeds.  I did a quick spreadsheet to see if the pressures for the switches at the link were in the needed range.  If I did the calculations right, it looks like the lowest airspeed for the lowest pressure switch at that link (7.5-145 psi range) is for 100 kts.

Tom,
