The Procedures Page is displayed by pressing the
PROC key. The Procedures Page provides direct access
to approaches, departures and arrivals — based upon
the active flight plan or direct-to destination. In either
case, the departure and destination airports must have
published procedures associated with them.
To select an approach, departure or arrival:
1. Press the PROC key to display the procedures page.
2. Turn the large right knob to highlight “Select
Approach?”, “Select Departure?” or “Select
Arrival?” and press ENT.
3. A window will appear listing the available pro-
cedures. Turn the large right knob to highlight
the desired procedure and press ENT. (When
a direct-to destination is selected, departures
are offered for the nearest airport.)
4. A second window will appear listing the avail-
able transitions. Turn the large right knob to
highlight 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 pro-
vide navigation guidance relative to the final
approach course.)
5. Turn the large right knob to highlight “Load?”
or “Activate?” (approaches only) and press
ENT. “Load?” will add the procedure to the
flight plan without immediately using it for nav-
igation 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 to later
activate a departure or arrival.
6. For precision approaches and some non-
precision approaches, a reminder window
will appear indicating that GPS guidance on
such approaches is strictly for monitoring only
— use the VLOC receivers and external CDI
(or HSI) for primary navigation. To confirm this
reminder, highlight “Yes?” and press ENT.
