[. . . ] This message results when RAIM unavailability is detected for more than 5 minutes at any point along the intended flight (based on BRNAV requirements). If a satellite is listed as `out of service' by NOTAM, you may use the `rem sat' (remove satellite) field to prevent a particular satellite from being used in the Route RAIM prediction (e. g. , removing satellite 9 in Figure 4). Figure 3 To exclude a satellite from the Route RAIM prediction: 1. Press E again to begin Route RAIM Prediction without using the selected satellite. 68 During route navigation, it is sometimes desirable to navigate a specified distance away from the `active leg' to help avoid certain airspaces or regions. The GPS 155XL's parallel track feature will automatically guide you along a selected offset from the active leg. Bearing and distance information will be to the waypoints along the original course, with the CDI centered on the offset course. To use offset navigation, or `parallel track': 1. Use K to display route 0 (parallel track can only be used on the active route). Use K and O to enter the desired distance and direction (R or L) from the leg. The Map Page will display the offset route as a solid line and the original route as a dashed line. ROUTE NAV Parallel Track Offset Navigation SECTION 4 Enter parallel track value after route activation. It is important to note that offset navigation is only available on route navigation, not direct-to navigation. If an approach is present in the active route, parallel offset navigation is cancelled when entering the 30 nm terminal area. "Approach not active" message will display if parallel navigation is re-instated after approach navigation has been armed. When offset navigation is activated, an `Offset nav in effect' message will be displayed with the distance and direction noted on the route catalog page for route 0. If you enter an offset which causes a leg to be reversed, you'll be informed with the message `Ofst too big for rte'. If you change the active route in any way or perform a direct-to, you'll be informed with an `Offset nav cancelled' message. Parallel Track 69 SECTION 4 ROUTE NAV Active Route Page Flying and Modifying the Active Route Once a route has been created and activated, the GPS 155XL will provide navigation to each route waypoint through the active route, NAV summary and map pages. From the active route page, you may also create and modify the active route, and insert an approach, SID or STAR. The NAV summary page will display detailed navigation data on your progress to each route waypoint, and provide turn anticipation, waypoint arrival and next desired track information. By understanding the relationship between the active route and NAV summary pages and the role of the waypoint sequencing (GPS SEQ) switch, you'll be able to get the most out of the GPS 155XL's advanced route and approach features. Whenever the GPS 155XL is navigating an approach, route or an on-route directto, the active route page will provide a list of the route waypoints in sequence, along with distance, time and course information. You may also create and edit a route directly from the active route page. If you want to save a route created from the active route page (route 0), you must copy it to an open storage route (see page 65) before turning the unit off or activating another route. The active route page may be displayed by pressing the R key and rotating O left continuously. It will also appear automatically whenever an approach, route, SID or STAR is activated. To scroll through the active route waypoints: 1. Rotate K with the cursor inactive (or O with the cursor active). USING THE ACTIVE ROUTE PAGE The GPS 155XL's active route page provides a working list of all waypoints for the route you are navigating, along with distance, timing or desired track information. [. . . ] The CDI scale will remain at the 0. 3 nm scale from the FAF to the MAP during the active approach. If you are in a missed approach situation, and would like to return the CDI to the 1 nm scale, you may deactivate the approach by releasing the GPS APR switch from the ARM position. Why does my CDI not respond like a VOR when the GPS SEQ switch is set to HOLD?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.
