If the AP display did not change to EFIS it is not getting ARINC steering signals from the AF-
ARINC module. Check the following:
i. Verify that the AP/FD LAT and VER sources are set correct; LAT HDG VER ALT
ii. If you have installed an AUTOPILOT Source Select switch is it in EFIS mode?
iii. Check the following connections:
AF-ARINC DB-25 Function Autopilot DB-25
25 ARINC Out B 15
13 ARINC Out A 14
g. Verify that the AP will follow the heading Bug, as you turn the heading bug left and right on
the EFIS screen the control stick should follow it.
If the control stick did not follow the heading bug check steps i. and ii. from above.
