APPROACHES 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 published approach. 1. Press the PROC key to display the procedures page. 2. Turn the large right knob to highlight "Select Approach?" and press the ENT key. 3. A window will appear listing the available procedures. Turn the large right knob to highlight the desired procedure and press the ENT key. 4. A second window will appear listing the available transitions. Turn the large right knob to highlight the desired transition waypoint and press the ENT key. 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. 5. Turn the large right knob to highlight "Load?" or "Activate?" and press the ENT key. "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. "Activate?" 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 indicating that GPS guidance on such approaches is strictly for monitoring only-use the VLOC receiver 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. As you select an approach, a "GPS" designation to the right of 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 guidance, 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. Activating the approach overrides the "en route" portion of the active flight plan, proceeding directly to the "approach" portion (for a full approach, directly to the approach transition). Activating the approach also initiates automatic CDI scaling transitions 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 airport. Later, if vectored to final, use the following 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. 16 190-00356-01 Rev H
