Selecting Approaches
In order to select an approach, you must first have an active
direct-to or flight plan that terminates at an airport with a pub-
lished approach.
Press the PROC key to display the Procedures
1.
Page.
2.
Turn the large right knob to
highlight "Select Approach?"
and press ENT.
3.
A window will appear listing
the available procedures.
Turn the large right knob
to highlight the desired
procedure and press ENT.
4.
A second window will
appear listing the avail-
able transitions. Turn the
large right knob to high-
light the desired transition
waypoint and press ENT.
(The approach "Vectors"
option assumes you will
receive vectors to the final
course segment of the approach and will provide
navigation guidance relative to the final approach
course).
Turn the large right knob to highlight "Load?" or
5.
"Activate?" and press ENT. ("Load?" will add the
procedure to the flight plan without immediately
using it for navigation guidance. This allows you
to continue navigating the original flight plan, but
keeps the procedure available on the Active Flight
Plan Page for quick activation when needed. "Acti-
APPROACHES
vate?" overrides the "en route" portion of the active
flight plan, proceeding directly to the "approach"
portion).
6.
For non-GPS approved
approaches, a reminder
window will appear indi-
cating that GPS guid-
ance on such approaches
is strictly for monitor-
ing only—use the VLOC
receiver and external CDI
(or HSI) for primary navigation. To confirm this
reminder, highlight "Yes?" and press ENT.
Not all approaches in the database are approved for GPS use.
As you select an approach, a
the procedure name indicates the procedure can be flown using
the GPS receiver. Some procedures will not have this designation,
meaning the GPS receiver may be used for supplemental navigation
guidance only. If the GPS receiver cannot be used for primary guid-
ance, you must use the appropriate receiver for the selected approach
(e.g., VOR or ADF). The final course segment of ILS approaches,
for example, must be flown by tuning the VLOC receiver to
the proper frequency and coupling the VLOC receiver to the
external CDI (or HSI).
A selected approach may be activated or loaded. Loading
the approach adds the procedure to the flight plan without
immediately using it for navigation guidance. You can continue
navigating the original flight plan, but the procedure is available
for quick activation when needed. Activating the approach over-
rides the "en route" portion of the active flight plan, proceeding
directly to the "approach" portion. 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, en route to the destination air-
port. Later, if vectored to final, use the steps to select "Activating
an Approach with Vectors-To-Final"—which makes the inbound
course to the FAF waypoint active. Otherwise, activate the full
approach using the "Activate Approach?" option.
