I fitted a digital fluxgate compass to the front of the roof just aft of
the windscreen. This is screwed to the roof having glassed in a plywood
base and will certainly not come loose accidentally. Any analogue
compass centrally mounted is difficult to read because of parallax
errors. I use the digital compass as a reference to update a DG so it is
only read occasionally. I also have a fluxgate feed to a RMI uEncoder.
With this set up you can mount the fluxgate unit wherever you want. I
put mine in the rear fuselage.

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?
