C. Adjustment
Before attempting to compensate compass, every effort should be made to place aircraft in
simulated flight conditions; check to see that doors are closed, flaps in retracted position, engine
running, throttle set at cruise position and aircraft in level flight attitude. Aircraft master switch,
alternator switch and all radio switches should be in ON position. All other cockpit controlled
electrical switches should be in OFF position.
NOTE: Use a non-magnetic screwdriver to adjust magnetic compass
(1) Set adjustment screws of compensator on zero. Zero position of adjusting screws is when dot
of screw is lined up with dot of frame.
(2) Head aircraft on a magnetic North heading. Adjust N-S adjustment screw until compass reads
exactly North.
(3) Head aircraft on a magnetic East heading and do same as Step 2, adjusting E-W adjusting
screw.
(4) Head aircraft on a magnetic South heading and note resulting South error. Adjust N-S
adjusting screw until one-half of this error has been removed.
(5) Head aircraft on magnetic West and do same as Step 4, adjusting E-W adjustment screw.
(6) Head aircraft in successive magnetic 30° headings and record compass readings on
appropriate deviation card. Deviations must not exceed ± 10° on any heading.
6. Magnetometer
In 6X S/N’s 3232014 & up and 6XT S/N’s 3255015 & up with the optional Avidyne Entegra Electronic
Flight Display System installed, the Magnetometer / OAT Sensor Assembly (Mag/OAT) mounted in the
underside of the outboard left wing, supplies magnetic heading information to the Primary Flight Display
(PFD).
See Appendix 2 (grid 3L3) for additional information.
