The problem: During my climb passing 10,000' (VNAV/LNAV/CLB Thrust), the autopilot obviously pitches for it's climb speed without the 250kt restriction. The issue is that acceleration to the new FMC speed and climb are extremely slow. We're talking 200/400FPM and 1kt every 3 seconds. The workaround for now: I can simply open the FSUIPC menu, make no changes, and click cancel or OK and the NGX is instantly climbing and accelerating at "normal" rates. Programs used: ASE (direct wind control mode [the source of my problem?]). FSUIPC registered (No wind smoothing options). Given what I can do to fix the issue, what would be the problem in the first place? There must be some significance in the fact that simply opening and then closing the FSUIPC menu will fix the issue.

My recommendation would be to wipe the fsuipc config file and start over - could be something weird in there. I have vague recollections of this happening to me either in FS9 or FSX a long time ago, and I think that was the fix I did. I could also be imagining that, of course. To check some other things, what is your TAT immediately before and after closing the menu, and what weather program are you using? -stefan edit: hurf durf I read good. Ignore the weather program question, I'm still interested in the TAT question.

It seemed normal to me for a 90F day. 5C at 10,000ft. I'll continue to mess around with it. I deleted the FSUIPC.ini file and copied my old hardware settings back in. We'll see how it goes.

I to have this problem...But the FSUIPC trick doesn't always work... So I often find myself clearing all weather, then back to normal.
