ENT
Key to
acknowledge the message.

ILS approach is loaded or activated, the ILS
frequency is automatically placed in the standby field of

Flying the ILS Approach
When ‘Activate?’ is selected for an
ILS approach,
automatic switching of the external CDI is enabled (unless
turned off from the CDI/Alarms Page). Once established
on the inbound course to the FAF, the external CDI
guidance automatically switches from ‘GPS’ (shown in
green text) to ‘VLOC’ (shown in white text). If the pilot
has forgotten to activate the ILS
frequency (step 4 below),
automatic selection of ‘VLOC’ does not occur (refer to
Figure 6-77 for the following steps).
