I replicated my winter instant action Take Off 1 mission flight and got similar results still. I'll submit a short track tomorrow. This one was over an hour long.

I appreciate it, will check where we are on this once you submit a new track. Thanks!

Done.

This time around I concentrated on doing a shorter stint to make the ADI did something weird and I sure managed to. It flipps in a way I haven't seen in the legacy module. But no drift was present during the flight.

Next I'll try to record a track of anctual Upgrade ADI drift, as I witnessed yesterday.

 

Flight profile:

Instant Action take off 1

flat wide turns and split S with initial climb, then level

Youtube video uploading to confirm we're seeing the same flips. The video starts right after I saw the first flip to make it occur again. It did.

In the legacy version it was enough for me to turn 90 deg on the ground to taxiway to induce a significant change in drift (see my previous youtube upload). As you can see, this time it was not the case. I even caused the 5 to make a 180 deg rapid twister skid. No ADI drift observed.

OK, drift replicated. It seems that it can be triggered on command, e.g. an ADI drift to the right can be triggered by a wide right turn. As you can see in my afternoon test flight I follow by "pushing the drift" to the left by a wide left turn.

I triggered the bug in 10 minutes and that includes the takeoff and climb.

What seems to be the problem is while there is an internal mechanism facilitating ........................... self-centering when in unaccelerated straight and level flight the threshold values used for detection of the conditions for self-centering are incorrect (too wide) so the ADI tries to level itself in shallow turns. This would explain the possibility to "reverse the drift" directly following a drift accurence.

OK, at this point I'm going to need further pointers as to what type of tracks to gather. I'm out of ideas for now.

Track: please disregard the second half of the track after 11th minute mark.
