I've noticed during radio navaid tracking, that it is still not holding a proper WCA. The aircraft will slowly drift downwind over time.

Hi, I've logged this for the team, are you able to link a video of this happening in the meantime for me to add for them as well. Thank you

I'll see what I can do. Naturally, the drift takes some time to occur, so to illustrate it happening would be a long-ish video.
