A330-900 Takeoff roll Instability

Post by adoceanum » Fri Dec 08, 2023 6:50 pm

After the A330 update on December 7th, I am unable to get the aircraft off the ground; during takeoff roll the airplane suddenly jumps 50 feet (aprox) off the ground, looses airspeed, and bounces up and down onto the runway. This has happened on 3 separate occasions and occurs at Vr, when you're rotating off the ground. I did not have this problem prior to the 12/7 update.

I am trying a delete and fresh reinstall of the A330, but wanted to see if this is a bug. No error on my end; plane is properly loaded and V speeds calculated accordingly. I screen captured a video of one of these incidents and it can be viewed here:

This is not behavior that is normal and we did not change much on the aerodynamics recently for it to behave this way after yesterdays update.

No significant changes at all.

What I think is you hit something there on the runway, initially when you were rolling (before V1) I saw you hit a bump on the video.

Can you try another airport please?

Thank you for the reply. I believe you are correct; tried a takeoff at a different runway/airport and there were no issues.

Must have been a rendering defect in scenery that created a hole/obstacle on the runway.
