When five or six years ago Andy Draper gave me a demonstration flight, the
compass fell off and rolled on the floor. It happened as we taxied back to the
hangar, but had it happened during a critical stage of the flight it could
have been potentially dangerous.
In view of this experience my strong preference is to fit the compass on top
of the instrument module, where it will be more secure. I know that some
Europa owners have gone for this option, even though the standard advice is to
keep the compass as far away as possible from other instruments, particularly
the tacho.
My question is this: have those builders who have fittted the compass on top
of the instrument module experienced unacceptably large false readings
caused by magnetic interference, or is the magnetic interference only a minor
problem?
