4) A reminder message appears, indicating that
GPS can only be used for approach monitoring.
As mentioned, the VLOC receiver must be
used for this approach. Press the ENT Key to
acknowledge the message.
When an ILS approach is loaded or activated, the ILS
frequency is automatically placed in the standby field of
the VLOC Window. To use this frequency, press the VLOC
Flip-flop Key to place it in the active frequency field.
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).
