A350 Pitching up violently on takeoff rotation

[alexanderbunda]

I'm not sure if anyone else has this problem, but right after V1 the aircraft takes off like a rocket with minimal sidestick input. I can't pitch the nose down, it only starts an aggressive stall once it runs out of speed.

Hello,

Do you perhaps have any conflicting axis' bound to your peripherals? Might be worth to check if any default MSFS assistance options are enabled that are fighting your manual inputs.

This issue has also been troubling me for a long time, but it seems it has never been fixed.

About 20 seconds after takeoff, the nose suddenly pitches up. Once the autopilot (AP) is engaged, it returns to a normal climb attitude. However, if the AP is engaged during this abnormal phase, then during landing, the moment the AP is disengaged, the nose also pitches up significantly.

It appears to be a trim parameter issue.

(All automatic assistance–related settings in the program have been turned off.)

Hi. Can you provide a video of the issue? If possible, enable the in-sim HUD (full) so we can see the manipulators

I have encountered this issue only when I pull up rather violently on takeoff.

If you pull back slowly, and then keep the nose at 10° or less (as you should) on takeoff, i rarely have this issue.

Since the plane usually wants to nose up on takeoff, slight down pressure on the stick helps.

This is the proper technique. The FBW trim system is actively adjusting on climbout so if you yank the stick back, it tends to over compensate and when you release pressure it needs to release the value which cause the crazy pitch fluctuations.
