I have returned to FS after 10 years' absence: I'm using FSX on a more than adequate PC dedicated solely to FS. A problem that I had with FS2004 (I think!) is now recurring in FSX and it must be something I am getting wrong: B737, Airbus and CJR700 insist on flying 10 degree nose-up. On AP altitude and speed are OK but flying by hand is a bit tricky with the nose-up attitude. No amount of trimming and engine speed adjustment seem to sort it out.

Prop aircraft are fine - the King Air is really great to fly - it's just with the jets that I have the problem.

Any hints on how to tackle this will be welcome. It was failure to overcome this issue that was a major factor putting me off FS all those years ago.

Could it be a CoG thing? Is it the same when you fly on fumes? Can't think why it should be wrong, though. Maybe it's the aircraft's flight dynamics model that is wrong. ;-)

It's either a speed, load (CG), or configuration (flaps/slats. etc) issue.... need more info...what specific plane, phase of flight, etc.... post a screen shot of the 2D cockpit if you can

I assume you're referring the default aircraft, so my first suggestion would be to forget the Airbus and CRJ because I think they both have dodgy flight models, especially the CRJ.

 

So, for the 737 (using the VC, not 2d panel), my first suggestion would be to load it up in FSX and use the menu to adjust the fuel down to say 30%, take-off, climb, gear and flaps up, auto throttle speed set to 300 and use the ap to climb to 15,000ft.  No you're plodding along on ap holding 15,000 at 300kts............what's your pitch like now?

I've never had that problem with both the default CRJ and the default 737.

 

Flying with that much nose-up attitude sounds like the is autopilot struggling to hold altitude due to a lack of airspeed. Are you sure you're flying at the correct velocities?

Paul I tried your suggestion and got perfectly straight and level flight at the height and speed indicated. So what has been wrong in the past I wonder - I must have had something wrong? How important was the fuel load, is it this that might have upset the trim in some way?

Thanks for the help, I'll work out into other situations from the stable flight that you have enabled me to establish.
