Simviation Forums

I am having a problem with my autopilot. Any jet I seem to use, the autopilot will climb for 5000 feet maybe 10,000 at the set rate, however it then slows upto 500fpm regardless of the rate set. I move it up or down the plane will start to climb a little faster but then go back to 500fpm.
Any ideas?
Thanks

Seems to happen to me too from time to time.. All you need to do is to reactivate the ALT hold after you change the vertical speed.
