PROCEDURES Procedure 1 GPS APPROACH NO PROCEDURE TURN An approach where there is typically no procedure turn required to get established on the inbound course to the FAF is the first example. We use GPS RWY 12 at KPRC to show how the G1000 sequences through an approach and what type of annunciation and range factor changes can be expected. This example is based upon and active flight plan from KFLG (Flagstaff, AZ Pulliam Airport) to KPRC (Prescott, AZ Love Airport). See figure 1. 1. Select KPRC as the destination, via the Direct-To key or as the last waypoint in a flight plan. 2. Press the PROC key and select the GPS RWY 12 approach. From the Transitions window, select IRODY as the IAF (select 'LOAD?' or 'ACTIVATE?'). 3. Within 30 nm of the destination, the G1000 switches from en route mode to terminal mode. The switch to terminal mode is accompanied by a gradual CDI range transition from 5.0 to 1.0 nm full range deflection. 4. Several miles prior to reaching the IAF (IRODY), review the approach sequence, as necessary. Press the FPL key to display the Active Flight Plan Page. Press the FMS knob and turn the large FMS knob to review each segment of the approach. When finished press the FPL key again to return to the previous page. 5. As the plane approaches the IAF (IRODY), the waypoint message 'NEXT DTK 204°' is displayed in the navigation status bar on the PFD. As the IAF approaches, the message is replaced by a turn advisory 'TURN TO 204°'. 6. As the plane approaches the IAP (OKAPY), the waypoint message 'NEXT DTK 124°' is displayed. As the waypoint approaches, the message is replaced by a turn advisory 'TURN TO 124°'. 7. At 2.0 nm from the FAF (MULHU), the G1000 switches from terminal mode to approach mode. CDI scaling is tightened from 1.0 to 0.3 nm full range deflection. 8. As the plane crosses the FAF 'NEXT DTK 124°' is displayed and the destination sequences to the MAP (RW12map, the runway threshold). Keeping the needle centered, fly toward the MAP, observing the altitude minimums dictated by the approach plate. 9. As the plane approaches the MAP, the waypoint message 'ARRIVING AT WAYPOINT' is displayed. 10. As the plane crosses the MAP, 'SUSP' is displayed in the HSI and directly above the SUSP softkey, indicating that automatic sequencing of approach waypoints is suspended at the MAP. A 'FROM' indication is displayed on the CDI, but course guidance along the final approach course continues. Do NOT follow this extended course. If a missed approach is required, follow the missed approach procedures as published on the approach plate. Press the SUSP softkey to return to automatic sequencing of waypoints. NOTE: When the message 'RAIM is not available' is displayed in the Alerts Window on the PFD a missed approach must be executed. NOTE: The final approach course must be intercepted 2 nm outside of the FAF for the approach to be active. 190-00368-04 Rev. A Garmin G1000 Pilot's Training Guide - Instructor's Reference 25
