Since SU5, there seems to have been introduced a bug in the Flaps Index value.
It’s a little complex to explain, but maybe the attached Screen shot may help.
If you use a STREAM DECK, PLEASE check it out and either confirm or deny you are seeing this.
If you INC / Dec the Flaps up /down, all is ok, unless when the Flaps are at Zero, you do one or more additional decrements. Then the Flaps Index get one out of step with the flaps lever postion and the flaps.
Ref Screen Shot,
1st 2 up / down cycles are OK, because there was not an extra DEC done when the Flaps Index was at Zero.
Then when Index was at zero, an additional Dec was done.
Then with the INC, the Flap position (green) moved, but the Index remained at zero, till the Flaps were Inc to position 2. (and Index was now 1 step behind at 1)
When you get to MAX Index, it re-syncs to the correct value.
If you have a Stream Deck, you can very easily see this happen in say the C172 ( G1000 or Steam)
STREAM DECK users, please try this and report back if you find the same issue, – if you do, we all need to submit a ZenDesk Ticket to get it fixed, to back pre SU#4
