An Air Swing is one of the five "approved" methods for a compass swing per AC 43-215 and is a viable alternative to the traditional method described above as requested per the OP.
From my experience an air swing is far easier and faster to accomplish. Kinda falls in the work smarter not harder category
Please educate me.

The compass needs to indicate the direction the nose of the aircraft is pointed. If airborne, the GPS may be indicating a ground track of 360 but due to a crosswind the nose of the aircraft is pointed several degrees east of ground track. How do you use the GPS in this situation to calibrate the compass?
