@bilalkah How did you solve the problem? I'm having exactly the same problem with you.

@Jaeyoung-Lim Thank you for your comment! I'm trying to control a Fixed-wing vehicle(actually, VTOL) in offboard mode(ros2) with waypoint lists, using TrajectorySetpoint(uORB) message. My goal is to make vtol behave...

@Jaeyoung-Lim [logfile](https://logs.px4.io/plot_app?log=7dfd87cc-c486-49c3-8761-b666fdd8f33b) Can I share it like this way? It is my first time to share log files to developers, so I don't know if it is enough to you....

@Jaeyoung-Lim Oh, I edited the original comment.

@Jaeyoung-Lim It is true that trajectory_setpoint is not streamed continuously, but that does not seem to be the cause. First, when I analyzed FixedwingPositionControl.cpp, I thought that trajectory_setpoint does not...

@Jaeyoung-Lim Oh, then it would be better to avoid discontinuous trajectory_setpoint publishing. Thank you! But I'm still wondering why altitude goes high even if I changed the code to continuously...

@Jaeyoung-Lim I'm sorry for the late reply. I tried normalizing velocity, and setting acceleration to nonzero value when I was publishing trajectory_setpoint, as you suggested, but it didn't work either.

@Jaeyoung-Lim Then should I report this to TECS implementation team, or did you already tell them? If I need to, how can I do it?

@Jaeyoung-Lim Thank you so much. I'll first try to examine the code myself, and post the issue again soon.

@Jaeyoung-Lim Hi, it's been a while. I found the reason and fixed it by modifying px4 source code. Could you check the new issue #23040 and pull request #23041 ?
