We are running a Classic PilotAware installed on a group owned PA-22. It is situated on the far right of the coaming and powered by the recommended Anker power pack.
All works fine - and has, without doubt, forewarned us of a potential conflict several times since installation in February - but we have begun to notice our standard compass wandering (situated directly in front of the P1 position, on the left, on top of the coaming.
The aircraft had its annual, which included a compass swing, in March 18.
Has anyone suspected that PilotAware has influenced their compass. PAW maybe completely innocent and it is an old aeroplane, but I would be interested to hear of any issue and, maybe, solutions.
We could install it on the back shelf, which will be very effective on a fabric covered aeroplane, on catching someone sneaking up behind us, but that would be much less useful, I would think for head on conflicts.
Many thanks, in advance, for any comments.
