A321 Oscillation

Post by Brett-Hill »

Just been flying the a321 AC CFM in fsx at high altitude (35,000ft @ 285kts AS) and I am getting a small bit of an up & down oscillation. it can been seen very well on wingview with the wing bending up and down with the pitch. Its as if the autopilot is a little slow in response to try and keep the Aircraft at that altitude... any ideas?

285 knots appears a bit slow. i thought the travel speed was about 470 knots.

Very simple
On the Aircraft.cfg section :
(FLIGHT TUNING)
pitch_stability=1.2 change to 2.0
save as usual.
Problem solved
