PROCEDURES
Activating
Approaches
5
Not all approaches in the database are approved for GPS use. As
you select an approach, a “ GP
S
” designation to the right of the proce-
dure name indicates the procedure can be fl own using the GPS re-
ceiver. Some procedures will not have this designation, meaning the
GPS receiver may be used for supplemental navigation guidance only.
ILS approaches, for example, must be fl own by tuning the VLOC receiver to the proper
frequency and coupling the VLOC receiver to the external CDI (or HSI).
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 fl ight plan,
proceeding directly to the “approach” portion (for a full approach, directly to the initial
approach fi x). Activating the approach also initiates automatic CDI scaling transition as
the approach progresses.
To activate an approach:
1. Press the P key to display the procedures page.
2a. Rotate the large right knob ( d ) to highlight “Activate Approach?” and press E .
Another procedures page option allows you to activate the fi nal course segment of the
approach. This option assumes you will receive vectors to the fi nal approach fi x (FAF) and
guides you to intercept the fi nal course, before reaching the FAF.
To activate the approach, with vectors to final:
1. Press the P key to display the procedures page.
2b. Rotate the large right knob ( d ) to highlight “Activate Vector-To-Final?” and press E .
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 steps above
to select “Activate Vector-To-Final”—which makes the inbound course to the FAF way-
point active. Otherwise, activate the full approach using the”Activate Approach?” option.
