Yes!

..and it is "swung" and has a card, and it is used (read)
often....

3 of our 4 pilots are also boaters..

The compass has no pumps, batteries, power supplies, and the
earths magnetic field has proven to be very reliable..

We keep in in "good order" , same as all other equipment on
the A/C...

A recent compass swing on our plane has turned up some opinions about
magnetic compasses that are surprising to me..

A club member has asked me why we spent money to have a 14 degree error
removed from our compass since it is just a back up instrument if everything
else quits. He just sets the DG to the runway heading on takeoff and uses
that. A couple of 360 in our 172 to look at something on the ground will
put our DG 15 -20 degrees off and it drifts about that much each hour. That
doesn't seem to concern him.

Snip


Are these casual attitudes towards compass accuracy I'm encountering common?
