Optional Interfaces
5.4.1
Autopilot
The EFD1000 E5 with ACU emulates a KI-525A, NSD-360A and PN-101 HSI by providing
HDG Datum, CRS Datum, and navigation L/R outputs to a connected autopilot. Any
autopilot compatible with the KI-525A, NSD-360A or PN-101 HSI is compatible with the
EFD1000 E5 System.
Note- the E5 does not support flight director display. The existing AI/FD indicator
(relocated) must be used for flight director.
Section 9 of this document shows interconnect diagrams for common autopilots that are
compatible with the EFD1000 E5. Because the EFD1000 E5 outputs Heading Datum and
Course Datum via the ACU the existing HSI/DG is no longer required to provide this
output to the autopilot.
When the EFD1000 E5 System is installed, the ACU controls all analog navigation signals
provided to the autopilot. Navigation signal output to the autopilot is switched
depending on which sensor is coupled to the EFD1000 E5 display. Therefore, the
LT/RT/UP/DN, flags, and ILS Energize must only be connected between the ACU and
autopilot, and there should be no direct connection between the navigation receiver and
the autopilot.
5.4.1.1
EA100 Adapter
See Appendix E for detailed EA100 installation eligibility. The EA100 can only be used to
replace the analog outputs from the attitude indicators and autopilots identified in
Appendix E. No other autopilot interfaces are authorized. KFC250 autopilots must have
the P/N 065-5016-XX Adapter Board to be eligible for connection to the EA100.
