(c) Place the aircraft on the South compass rose heading. Rotate the indicator card to South
using the manual slave buttons on the slaving control. With a non-magnetic screwdriver in
the N/S opening on the slaving control, adjust to remove one-half (1/2) of the existing
deviation shown by the slave meter.
(d) Place the aircraft on the West compass rose heading. Rotate the indicator card to West
using the manual slave buttons on the slaving control. With a non-magnetic screwdriver in
the E/W opening on the slaving control, adjust to remove one-half (1/2) of the existing
deviation shown by the slave meter.
(e) If deviation (difference between actual magnetic heading and what compass indicates on
that particular heading) exceeds ± 10° on any heading, instrument replacement may be
necessary. To verify, do the following:
1 Check whether any magnetic metals are near compass (tools, flashlights, pocket
knives, wristwatches, etc.)
2
Check to be sure screwdriver being used to make adjustments is either fiber or a
non-magnetic metal, such as brass.
3
When satisfied that errors in excess of 10° are the fault of the instrument, replace
instrument. After installing a new instrument, repeat procedures (1) and (2).
(f) After all adjustments are completed, the indicator shall read within ± 2° of any compass
rose heading on which the aircraft is placed.
