See here, you can see that "AFCAS Target" flickers on and off, and it looks like in some circumstances the ATS system isn't actually trying to "track" the selected speed.

This is not a problem in what I would call "managed" mode.

Keep in mind, I haven't yet gone through the manual thoroughly, so I apologize if this is known/expected and caused by user error.

This is happening to me now the F70 (v. 1.0.1) but also happened a few days ago with the F100 (v. 1.0.0.).

To reproduce, once you are in cruise, pull the speed knob towards you and select a different speed, once the aircraft is close to that speed the AFCAS Target indication will start to flicker, from that point on if you try to adjust the speed, the changes won't always be reflected by the blue indication in the speed tape and the ATS won't always react in the way I would expect it to.
