SECTION 6

PROCEDURES

5)Turn the large right knob to highlight ‘Load?’ or ‘Activate?’ (approaches only) and press the ENT Key. (‘Load?’ adds the procedure to the flight plan without immediately using it for navigation guidance. This allows the pilot to continue navigating the original flight plan, but keeps the procedure available on the Active Flight Plan Page for quick activation when needed.)

6)For precision approaches and some non- precision approaches, a reminder window appears 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 the ENT Key.

Not all approaches in the database are approved for GPS use. When selecting an approach, a ‘GPS’ designation to the right of the procedure name (Figure 6-4) indicates the procedure can be flown using the GPS receiver. Some procedures do not have this designation, meaning the GPS receiver may be used for supplemental navigation guidance only. 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).

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.

Activating an approach:

1)Press the PROC Key to display the Procedures Page (Figure 6-5).

2)Turn the large right knob to highlight ‘Activate Approach?’ (Figure 6-5) and press the ENT Key.
