Dual Control Mode Truth Table - Honeywell Primus 880 Pilot's Manual

The third system configuration is similar to the second except that a
Honeywell multifunction display (MFD) system is added. As before,
single or dual controllers can be used. When a single controller is used,
all displays show the same radar data. Dual controllers are used to
operate in the dual mode. The MFD can be slaved to either controller
to duplicate the data displayed on the selected side. Table 2- 1 is a truth
table for dual control modes.
