acid free white kerosene
fill compass/ get A&P to replace tubing

I'm curious, for those that know sailboat and airplane compasses, why the
difference in fluids?

In sailboats, I was told the reason for using mineral oil was to dampen the
movements, with the more viscous fluid doing that function.

I would think that airplanes would need the same characteristics of the
dampened movement, but yet, people are saying that the thinner kerosene is
the fluid of choice to use in the compass.

Anyone got any insights to this?
