PROCEDURES Procedure 10 FLYING THE ILS APPROACH NOTE: When an ILS approach is loaded, the ILS frequency is automatically placed in the NAV Frequency window. Refer to the NAV/COM Pilot's Guide for details. Precision approaches can be performed with the built in Nav (VOR/localizer/glideslope) receivers. Prior to reaching the FAF the CDI should be set to NAV1 or NAV2. The G1000 automatically switches the external CDI output from GPS to NAV1 or NAV2 as the final approach course is intercepted. When the ILS approach is activated, the G1000 automatically switches within 1.2 nautical miles left or right of the final approach course. This switch will take place within 15.0 nautical miles prior the FAF. NOTE: If an attempt is made to intercept the approach course beyond the FAF, the CDI must be manually switched from GPS to LOC1 or LOC2 by pressing the CDI softkey. The CDI selection can also be changed manually by pressing the CDI softkey. Once the switch from GPS to Nav has occurred, either automatically or manually, it does not automatically switch again until the approach is reactivated or another approach is selected. To prevent automatic ILS CDI selection, select the 'Manual' ILS CDI Capture, in the AUX - System Setup Page (the factory default setting is 'Auto', which enables the automatic switch to Nav). This example is based upon on an active flight plan from KSNA (Santa Ana, CA ) to KSAN (San Diego, CA Lindbergh Field) with the ILS RWY 9 approach and "GATTO" as the IAF, which includes an outbound leg and a procedure turn. See figure 7. 1. Select KSNA as the destination, via the Direct-To key or as the last waypoint in a flight plan. 2. Press the PROC key and select ILS RWY 9 approach. From the transition window, select 'GATTO' as the IAF. Choose 'LOAD?' or 'ACTIVATE?'. A reminder message is displayed, indicating that GPS can only be used for approach monitoring. 'LOAD' will maintain Direct-to navigation, while activate goes directly to the first fix. Activate the approach once cleared by ATC. 3. Within 30 nm of KSAN, the G1000 switches from en route mode to terminal mode and the CDI range transitions from 5.0 to 1.0 nm, full-range deflection. 4. If the approach has not already been activated, be sure to do so when cleared for the approach. 5. As the plane approaches the IAF (GATTO), the waypoint message 'NEXT DTK 272°' is displayed in the navigation status bar on the PFD. As the distance to the IAF approaches zero, the message is replaced by a turn advisory 'TURN TO 272°'. 6. Fly the outbound course (272°), keeping the CDI needle centered. 7. Once the plane has flown approximately one minute past the IAF (GATTO), the message 'START PROC TURN' is displayed. 8. Turn left to a heading of 227° to initiate the procedure turn. The G1000 does not guide one through the turn (the procedure turn is displayed in magenta indicating the active leg). The CDI needle starts moving to the right. 9. After approximately one minute, make a 180° right turn to a heading of 047° to intercept the ILS. The G1000 sequences to the inbound leg and 'NEXT DTK 092°' is displayed. CDI coupling automatically switches from the GPS receiver to the Nav receiver as the plane completes the inbound turn. 10. As the CDI needle starts to center, make a right turn to 092° to track the ILS approach course. 11. At 2.0 nm from the FAF (GATTO), the G1000 switches from terminal mode to approach mode. The CDI scaling is tightened from 1.0 to 0.3 nm, full range deflection. 12. As the plane approaches the FAF (GATTO), the waypoint message 'NEXT DTK 092°' is displayed. 40 Garmin G1000 Pilot's Training Guide - Instructor's Reference 190-00368-04 Rev. A
