In the U.S., "ramp checks" (especially of gliders) are relatively rare where an FAA representative will, without warning, approach an aircraft and check to make sure it complies with regulations.
During a flight review a few weeks ago, the CFI-G said that one subtle issue that catches a number of aircraft owners is the compass. FAA regulations say that every aircraft must have a "calibrated" compass -- not just a compass. So, during a ramp check, one of the things the FAA rep looks for is entries on the compass calibration card. No entries? Airplane is grounded & a fine is levied.
Although I am not suggesting that you do this, he mentioned that until you have time to calibrate your compass, even just writing some numbers on the card will prevent a fine. Then just "swing it" next time you can either get on a compass rose at the airport or with your gps while flying.
