BEagle, do you have a reference for that? The instructors I've spoken to about it seem to be split on whether this is, in fact, the case.
But even if we agree we can carry students without meeting the 3/90 rule, let's also agree that if you do a lesson in a 4-seat aircraft with "passengers" in the back, then you must meet the requirements for carrying passengers..... correct?
