What does that have to do with compass fluid? Compass checks are
carried out during taxi, particularly for an IFR flight. Attitude
indicator erect and steady; heading indicator set and indicating
during turns; turn coordinator functioning and ball free; compass free
and floating, altimeter set and indicating proper elevation, radios
set. That's about as much as I can remember, since my Instrument
ticket lapsed eight years ago.
Compass is not part of the preflight.

Tell me: what does the compass do in a turn to or from North
versus a turn to or from South? Why does this make it useless for
rolling out on a heading unless we use a timer?
