April 1995 190-00065-00 Rev. [. . . ] The line connecting these waypoints is known as the `active leg'. If you are navigating a direct-to, the field will display the destination only. 57 DIRECT-TO & ROUTE NAV Adding Active Route Waypoints The `cum or leg' field can be selected to display cumulative distance and ete/eta or the distance and ete/eta for each individual route leg. If cumulative is selected, the first leg's distance will be displayed, while the second leg will represent the first leg's distance plus the second leg, and so on. This also applies to the ete/eta field, which may also be configured to display the desired track (dtk) for each leg, regardless of the cumulative or leg selection. To change the leg and ete/eta fields: 1. With the flashing cursor active, rotate O to highlight the field you want to change. Rotate K to select the desired setting and press C. Active route page with desired track displayed. The active route page may also be used to create a new route or edit the route you are currently navigating (approach, SID or STAR waypoints cannot be edited), and provides a fast method of selecting any route waypoint as your next destination waypoint without modifying the active route. If you are editing the active route and want to save it in its original form, copy it to an open storage route before editing. To add waypoints to the active route: Adding a waypoint to the active route. 1. Press C, if necessary, to activate the cursor. Use O to highlight the first blank waypoint field or highlight the waypoint you would like to add the new waypoint BEFORE. Use K and O to enter the new waypoint identifier. Press E. Confirming the new route waypoint. 4. The cursor will automatically move to the next waypoint field, and the remaining route waypoints (if any are present) will move down the list accordingly. 58 To delete a waypoint from the active route: 1. Press C, if necessary, to activate the cursor. Use O to highlight the waypoint you would like to delete from the active route. The next route waypoint (if available) will move up to take the position of the deleted waypoint. DIRECT-TO & ROUTE NAV On-Route Direct-To The active route page also allows you to select your next destination waypoint manually from the active route waypoint list and resume the remainder of the route in sequence. This procedure, referred to as an `on-route' direct-to, allows the pilot to fly the active route in a different sequence without editing the active route, approach, SID or STAR itself. For example, if you are flying a route with an armed approach, the GPS 155 will automatically provide the initial approach fix (IAF) for the selected approach as your `active to' waypoint. If you have been vectored directly to the final approach fix (bypassing the IAF), you can manually `skip ahead' to the final approach fix as your next active to waypoint. To perform an on-route direct-to from the active route page: 1. Press C and rotate O to highlight the desired waypoint. Press D, followed by E to confirm the `ok?' prompt on the waypoint confirmation page. Manually selecting the next active route waypoint. Confirming the on-route direct-to. The GPS 155 will now provide guidance to the direct-to waypoint with the CDI page, and resume navigating the remainder of the active route in sequence once you arrive at the direct-to destination. See Section 4 for more on approach navigation. CDI page with new destination waypoint. 59 DIRECT-TO & ROUTE NAV Turn Anticipation While the active route page offers the necessary functions for creating, monitoring and modifying the active route, the GPS 155's CDI page is used to provide turn anticipation, next desired track and waypoint arrival information to the pilot. The GPS 155's turn anticipation feature smooths out the transitions between adjacent legs based on a nominal bank angle of 15º, with the ability to roll up to 25º. If the turn angle and your present speed will require a bank angle that exceeds 25º, you'll be notified with a `Steep turn ahead' message approximately 90 seconds before arrival at the active to waypoint. [. . . ] 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 APPR 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. Therefore, the CDI deflection on the GPS will be consistent regardless of the distance to the destination, and will not become less sensitive when you are further away from the destination. [. . . ]
