A. King KCS-55A Slaving Compass (with HSI)
(PIR-PPS60081, Rev. C)
The King KCS-55A may be installed as an option in non-EFIS equipped airplanes, S/N’s 2842201 and up.
(1) Flux Detector (See Figure 4.)
A flux detector installed in the left wing tip, by W.S. 207.40, provides heading data to the HSI.
CAUTION: PERFORM MAGNETIC HEADING COMPENSATION/CALIBRATION, BELOW,
WHENEVER THE FLUX DETECTOR IS CHANGED.
(a) Removal
1
Remove the left wing tip fairing to expose the flux detector.
2
Disconnect the wiring harness from the top of the flux detector.
3 To remove the flux detector, remove the three (3) brass screws and washers
attaching it to mounting bracket.
(b) Installation
CAUTION: THE FLUX DETECTOR IS SECURED TO THE MOUNTING BRACKET
WITH BRASS SCREWS. ENSURE ONLY BRASS SCREWS ARE USED
WHEN REINSTALLING.
1 Place the flux detector into position on its mounting bracket and secure with brass
screws and washers (3 ea.).
2 Connect wiring harness to the connector on top of the flux detector.
3
Reinstall the left wing tip.
NO
TE: Ensure correct hardware is used when reinstalling wing tip over flux
detector.
(2) Flux Detector Index Error
(a) Place the airplane in simulated flight conditions:
1 Check to see that the doors are closed and flaps are in retracted position
2 Have the engine running at idle (1000 rpm), with the airplane at a level flight attitude.
3
Put the battery master, alternator and all radio switches in the ON position.
4
Power ON the KCS-55A (allow to synchronize).
5 Turn lights – recognition, instrument panel, navigation, position, and strobe – ON.
(b) Place the aircraft on a compass rose in each of the four cardinal headings. At each
cardinal heading, with the slaving control in the “Free Gyro” position, center the slave
meter with the manual slave buttons on the slaving control, and record the difference (plus
or minus) between the cardinal heading and the indicator heading.
(c) Add the four differences, and divide the sum by four. The result is the index error.
(d) Loosen the mounting screws on the flux detector, and rotate the unit as required to cancel
the index error (ex.: if the index error is +2°, set the indexing device at -2°).
(e) Retighten the mounting screws.
