[SOLVED] Negative pitch, minimal climb and no speed increase

Recommended Posts

Hello

I'm having some very strange issues with the 737NGX. I start it up from the stock cold and dark state, taxi and take off. No problems during that phase. But once in the air the aircraft doesn't climb well or gain speed. The PFD shows a negative pitch yet the aircraft is still in a climb. Engines run at normal climb thrust (e.g. ~88%). When I increase the thrust manually the nose goes down to -5 degrees without the aircraft gaining any more speed then 220 kt while still climbing at a small rate.

I use P3D v4.3 and re-installed the 737 package in attempt to fix the issue.

The only thing that has changed since the last successful flight (which has been a while ago) is the throttle input. I've replaced a failing throttle lever with Saitek Throttle blocks and I'm using them via FSUIPC rather then the default interface. Didn't give me problems with any other PMDG or other product. Yet I mention it as it's the only change that has been made. Couldn't really verify it as the source of the issue however and the throttle works just fine on the plane.

Here's a picture of just such a state:

Did anybody else encounter such issues? Is this a known problem? What steps would you suggest to troubleshoot?

Thanks

Hi,

It is a known issue with FSUIPC where the profile gets corrupted and though the flaps are retracted, they are still considered as deployed.

Delete the FSUIPC profile and build a new one from scratch.

Looks like that fixed it. Just removing the profile didn't do it but after I removed the entire ini file and rebuilt the profile it worked. Gonna play it safe and rebuild it for all aircraft.

Thanks for your help.
