FSUPIC and PMDG 737

[Jim Harnes]

With FSUPIC set with defaults, my PMDG 737 performs perfectly. However, when changing to any other settings, the aircraft VNAV climb speeds and feet-per-minute rates and VNAV path altitude hold do not function properly. For example, with a cruise altitude of FL370 set in the MCP and VNAV path showing on the PFD, the altitude constantly varies +/-120-200 feet. Of course TAS chases altitude. When I reset FSUPIC to defaults, normal aircraft flight behavior returns. This happens with all weather setting cleared, i.e., clear weather, no wind.

Having registered FSUPIC, I want to use its non-default features.

BTW, this happens with 3.14 and the version provided by PMDG, 3.129.

Are there log settings which might point to the cause?

Thanks,

Jim Harnes

That surely cannot be so with any individual options. They all do different things. The ones that may do things like that are "Enable V/S sign correction" and "Reverse the elevator trim sense" on the Technical page. Don't enable either of those when using any non-default autopilot.
