The actual CG. I would think that most retracts would change CG since at least the nose gear is in a different position relative to the datum, but I can only speak for the Arrow that I flew for my checkride.

Interesting - never thought much about it. Looking at the Arrow manual,
I see "moment due to retraction of landing gear" 819 in-lbs". Dividing
by 2000 lbs gives a CG change of about a half an inch.

Thanks.
