After playing with the 55 simulator I’m sort of glad the SR20 installation doesn’t force alt. preselect on us; too damned complicated, particularly in the approach phase.
Bernie: Thanx for the tip.
Got it working. Re installed WinZip (was using Norton zip). I agree that the alt option is a bit tricky but am still inclined to order this option with the feeling that it would be used more after I got used to the other aspects of the SR20.
If nothing else, it would work as a backup altimeter and remind you to double check DH or MDA. Having said this, I agree it is not the most user freindly interface.
What we need now is a program that lets us practice with the Garmin 430 and S stec 55 together!
