SECTION 6 PROCEDURES Select Destination 'Select' and 'Load' the approach 'Activate' the approach DO NOT USE FOR NAVIGATION 4) 'Activate' the full approach or vectors-to-final, as appropriate. In some scenarios, it may be more convenient to immediately activate the approach and skip the 'Load' process outlined in the preceding step 3. The GNC 420 provides both options. Approaches with Procedure Turns The procedure turn portion of an approach is stored as one of the legs of the approach. For this reason, the GNC 420 requires no special operations from the pilot (other than flying the procedure turn itself) beyond what is required for any other type of approach.  Lynchburg (VA) Regional VOR or GPS Rwy 03   Figure 6-8 Sample Approach Approach operations on the GNC 420 typically begin with the same basic steps (refer to Figure 6-8 for the following steps): 1) Select the destination airport using the Directto Key, or as the last waypoint in the active flight plan. 2) Choose the 'Select Approach?' option from the Procedures Page (Section 6.1) or from the Active Flight Plan Page Menu (Section 5.2, Active Flight Plan Options). 3) 'Load' the approach (often while enroute) in anticipation of its future use. This places the approach in the active flight plan, but retains course guidance in the enroute section until the approach is 'activated'. DO NOT USE FOR NAVIGATION Figure 6-9 Sample Approach with Procedure Turn This example uses the VOR Runway 03 approach for Lynchburg (Virginia) Regional Airport, KLYH, and assumes a departure from Frederick (Maryland) Municipal Airport, KFDK. 6-4 GNC 420(A) Pilot's Guide and Reference 190-00140-20 Rev.
