You can't do a full and free rudder check on a stationary PA 28 either, nor did the guy who did my 170a expect me to. I just followed the check list I use normally in my usual reasonably careful and practical fashion and he seemed happy enough.
Edited to add: Are you dealing with some muppet who is trying to make a point about FAA vs JAA/EASA. If so he's made the point that the FAA regime is sensible and other one isn't!
