[. . . ] (When viewing the Map Page as in Figure 6-87, note that the final course segment is displayed in magenta (the active leg of the flight plan always appears in magenta), and a dashed line extends the course beyond the MAP. ) 14) When approaching the MAP, a waypoint alert (`APPRCHING WPT') appears in the lower right corner. GNS 430 Pilot's Guide and Reference 6-31 SECTION 6 PROCEDURES 15) After crossing the MAP, `SUSP' appears above the OBS Key (Figure 6-88), indicating that automatic sequencing of approach waypoints is suspended at the MAP. A `FROM' indication is displayed on the CDI and Default NAV Page, but course guidance along the final approach course continues. Follow published missed approach procedures, using the OBS Key to initiate the missed approach sequence. 6. 4 POINTS TO REMEMBER FOR ALL APPROACHES · The GNS 430 is designed to complement printed approach plates and vastly improve situational awareness throughout the approach. However, the pilot must always fly an approach as it appears on the approach plate. · The active leg (or the portion of the approach currently in use) is depicted in magenta on the Map Page. When flying the approach, the GNS 430 automatically sequences through each leg of the approach unless `SUSP' appears above the OBS Key. `SUSP' indicates that automatic sequencing of approach waypoints is suspended on the current leg and normally appears at holding patterns and upon crossing the missed approach point (MAP). Figure 6-88 `SUSP' Annunciation NOTE: In addition to using the OBS Key to initiate the missed approach sequence, the CDI Key may be used to manually switch the external CDI output to the GPS receiver. If the pilot leaves the CDI output on `VLOC' and the pilot is using an external CDI (not an HSI), expect reverse sensing on the backcourse of the ILS. 6-32 GNS 430 Pilot's Guide and Reference SECTION 6 PROCEDURES Points to Remember for Localizer-based Approaches · The default factory setting allows the CDI output to automatically switch from the GPS receiver to the VLOC receiver. If the `ILS CDI Capture' setting is changed to `Manual', the pilot must determine when to select GPS or VLOC guidance during the approach. Remember, VLOC is required for the final course segment from final approach fix (FAF) to MAP. · If the CDI output has not automatically switched from GPS to ILS by 2. 0 nm prior to the FAF, the pilot must manually switch to the VLOC receiver by pressing the CDI Key. · Automatic switching of CDI output is available for ILS, localizer, SDF, and LDA approaches. · When flying an approach with the autopilot coupled, the pilot must monitor system functions at all times and verify that the autopilot and external CDI (or HSI) switches to the VLOC receiver with sufficient time to capture and track the approach course. Switching to VLOC late in the approach may not provide the autopilot enough time to respond and intercept the approach course prior to the FAF (depending upon the performance characteristics of the autopilot and aircraft). In such cases, the pilot should manually fly the approach or refer to the documentation provided with the autopilot. · When an ILS approach is first selected and `loaded' (or `activated'), the ILS frequency is automatically placed in the standby field. In order to fly the final course segment of the ILS approach, the pilot must place the ILS frequency in the active frequency field by pressing the VLOC Flip-flop Key. If this is not done, a `Select appropriate frequency for approach' message appears within 3. 0 nm of the FAF. · When flying a localizer-based approach (other than backcourse) with automatic CDI switching enabled: GPS guidance is used while flying outbound and on the initial portion of the procedure turn. VLOC guidance is used on the remainder of the approach from the time the pilot turns inbound on the procedure turn. · When flying a localizer-based approach with automatic CDI switching disabled: The pilot may select VLOC guidance at any point on the approach prior to reaching the FAF. The localizer frequency must be active to use VLOC guidance.

This second page group (WPT) provides information for the thousands of airports, VORs, NDBs, intersections, runways, frequencies, and procedures stored on the Jeppesen NavData card. [. . . ] For more information on waypoint alerts and turn advisories, see Sections 6. 2 and 6. 3. Figure D-6 CDI at 1 nm Scale MAP Approach 0. 3 nm FAF 2 nm 1 nm When does the CDI scale change, and what does it change to? The GNS 430 begins a smooth CDI scale transition from the 5. 0 nm (enroute/oceanic mode) to the 1. 0 nm (terminal mode) scale 30 nm from the destination airport (Figures D-6 and D-7). The CDI scale further transitions to 0. 3 nm (approach mode) at 2 nm prior to the FAF during an active approach. If the pilot is in a missed approach situation, and would like to return the CDI to the 1 nm scale, activate the missed approach sequence by pressing the OBS Key, as described in Section 6. 2, Flying the Missed Approach. The CDI scale is also 1. 0 nm (terminal mode) within 30 nm of the departure airport. 5 nm 1 nm 1 minute 30 nm Enroute/Oceanic CDI Scale Transition Figure D-7 CDI Scale Transition GNS 430 Pilot's Guide and Reference D-5 APPENDIX D TROUBLESHOOTING Why does my CDI not respond like a VOR when OBS mode is active? Unlike a VOR, the CDI scale used on GPS equipment is based on the cross-track distance to the desired course, not an angular relationship to the destination (Figure D-8). [. . . ]
