4.2 Pro Digital Configuration
The following configuration shows a Pro Digital installation, without an advanced autopilot
and flight director. No ACU is required for this installation. This installation would be used
when there is no analog VLOC receiver and the autopilot L/R input is dedicated to the GPS.
The PFD navigation source selection has no control over the autopilot input. Dual digital
radios may also be connected with or without a “Tracker” autopilot.
Tracker autopilots that use L/R steering can also be wired to an ACU so that the PFD displayed
navigation source L/R output is switched to the autopilot. These installations will be wired as
shown in Figure 4.3 minus the heading and course datum, flag, ILS Energize, and glide slope
signals.
