Taxying out on Saturday, on my way to the Ice Cream Social, I noticed that the compass was about 90? out. Tapping the glass didn't help.
On the flight the compass just seemed to randomly rotate as though it was completely demagnetised. I've never heard of this happening before. I haven't made any changes behind the panel since it was last working normally.
If it has demagnetised, does anyone know how this happened and can it be re-magnetised?
On a more positive note, it was my first long cruising flight since fitting a P-Mag and I got the EGT to come down from peak while leaning, on a carburetted O320, and fuel burn was about 10% improved cruising at 155 KTAS and 10,500'.
