How are you going to fly an ATC heading without a good compass?

It's been my experience that ATC provides a heading for you to fly and keeps an eye
on you for a while to make sure that you are flying the course they actually want. If
your compass is off by, say, 10 degrees, they will give you a corrected heading to
fly.
