A selected approach may be activated or loaded. Once
an approach is selected, it may be activated for navigation
from the Procedures Page. Activating the approach
overrides the 'enroute' portion of the active flight plan,
proceeding directly to the 'approach' portion (for a full
approach, directly to the initial approach fix). Activating
the approach also initiates automatic CDI scaling transition
as the approach progresses.
In many cases, it may be easiest to 'Load' the full
approach while still some distance away, enroute to the
destination airport. Later, if vectored to final, use the
following steps to select 'Activate Vector-To-Final'—which
makes the inbound course to the final approach fix (FAF)
waypoint active. Otherwise, activate the full approach
using the 'Activate Approach?' option.
Activating an approach:
1) With an approach loaded in the active flight
plan, press the PROC Key to display the
Procedures Page.
Turn the large right knob to highlight 'Activate
2)
Approach?' and press the ENT Key.
The 'Activate Vector-To-Final?' option allows the pilot
to activate the final course segment of the approach. This
option assumes the pilot will receive vectors to the FAF
and provides guidance to intercept the final course, before
reaching the FAF.
