Notes:
[1] For KAP 150/KFC 150, EFIS-enabled KC-19X computer (P/N 065-0042-16) is not supported.
[2] The heading error and course error signal characteristics are determined by the autopilot that is selected in the Interfaces settings.
[3] An attitude source must be provided to the autopilot in order for it to function properly. The KVG 350 gyro or the KI 255/256 ADI may be retained, or
the KG 258 ADI may replace the KI 256 ADI to provide attitude information to the autopilot system. Optionally, the GI 275 may be used instead of
the KI 255/256/KG 258 ADI or the KVG 350 gyro to provide attitude information to the autopilot system.
[4] For the KFC 300 autopilot, a synchro heading input is required. The existing KCS 305 compass system (KSG 105 slaved directional gyro) may be
retained to provide heading information to the autopilot system.
[5] The original attitude and heading system must remain in the aircraft to provide attitude and heading inputs to the autopilot. The original Altitude Alert
Controller must be retained.
[6] The autopilot computer must be configured for a Collins PN-101 (FD-112C/V) HSI. If the autopilot had another HSI prior to the installation of the
GI 275 system, changes to the GDU emulation setting may be required (the installation that was evaluated was an M-4D that had a Collins
FD-112 HSI/ADI in the original configuration).
[7] The KCI 310 indicator contains a Test key that is used to initiate the KFC 300 self-test. If the KCI 310 indicator is removed, an external momentary
switch must be installed to replace the function of the KCI 310 Test switch.
