Dear Mark,
Thank you for getting back to me and for sharing the reference video.
However, I would like to point out a few things regarding the video provided. Since it was recorded from the passenger cabin, it lacks the flight deck parameters (such as EPR, IAS trend, and wind vectors) necessary to make a direct and accurate comparison between the real aircraft's ATS behavior and the simulator.
Furthermore, the meteorological conditions in the video clearly show active weather, with nearby CBs and apparent turbulence. In an environment with shifting wind direction and speed, it is completely normal and expected for the ATS to make significant and continuous thrust adjustments to maintain the target speed.
This contrasts directly with the video I recorded and sent to you. In my simulator footage, you can see that the wind direction and speed are completely constant. While perfectly steady winds are too unreal, in this controlled environment, a stable wind vector should not trigger such erratic ATS responses and severe thrust hunting. Without external atmospheric disturbances, the system should be able to stabilize the power setting rather than continuously chasing the speed.
I'll sent a ticket as instructed!
Thank you again for your time and assistance.
