7.2.5 ACU Wiring
Wire as shown in Section 9 keeping all grounds as short as possible. No additional
HIRF shielding is required. The ACU case must be grounded to airframe ground for
proper operation.
7.2.6 Back Up NAV Indicator Wiring
Wire as shown in Figures 9.24, 9.25, and 9.26. Do not parallel more than one NAV
Indicator to each ACU. When paralleling the wiring make the splice as close to the
navigation receiver as practical. Do not splice the connection at the back of the NAV
indicator.
7.2.7 Autopilot Wiring
Wire autopilot to ACU as shown in Section 9. Remove any existing connections and
switching between GPS and NAV receivers to autopilot. Only ARINC 429 wiring may
remain between the GPS and autopilot for NAV mode GPSS. The ACU will perform all
switching functions to autopilot for GPS1, GPS2, NAV1, and NAV2.
