The CPA function calculates the closest distance that a route will pass to a reference waypoint, and helps you create new route waypoints referencing a NAVAID. Navigation Units Closest Point of Approach APPENDIX A ROUTES SECTION 5 Calculating Closest Point of Approach. KLIT To calculate the closest point of approach (CPA) from the route catalog page: 1. Use K to display the route you would like to use for the CPA function. The route must consist of at least two waypoints, and the reference facility must fall between the waypoints of a route leg. Press C twice and rotate K to select `cpa?'. Use K and O to enter the identifier of the reference waypoint. The bearing and distance of the closest point on the route will be displayed. Press E to add the cpa waypoint to the route, or \ to finish. If you do add the cpa waypoint to the route, it will be named based on the reference waypoint plus a number (09) appended to the end (e. g. , KMCI3 for KMCI). If the waypoint does not fall between waypoints on the route, the reference waypoint does not exist or a unique name cannot be assigned to the CPA waypoint, you'll be informed with an `Invald CPA wpt ____' message.

This is done in reference to two waypoints called `anchor waypoints'. The first leg will be a specified distance from the line connecting the anchor waypoints. This is called the `offset distance'. The `increment distance' is the distance between each subsequent leg. Note that bearing and distance information are referenced to the anchor waypoints. The ladder can be created on either side of the waypoints. To perform a search and rescue operation: 1. Create a route of only two waypoints. ANCHOR WAYPOINT 2. Press R and use O to display the route catalog page. Use K to select the 2-waypoint route. LEG LEG LEG INCREMENT INCREMENT INCREMENT DISTANCE DISTANCE DISTANCE 4. Press C twice and use K to display `search?'. Use K and O to enter the leg increment value and R or L. Rotate O to highlight the initial offset, and use K and O to enter the initial offset value, and R or L. [. . . ] 3) The To/From indicator on the GPS CDI will flip momentarily to indicate that you have crossed the midpoint of the turn. For more on turn anticipation, see Section 5. When does the CDI scale change, and what does it change to?Whenever an approach is selected, the GNC 300 will begin a smooth CDI scale transition from the 5. 0 nm to the 0. 3 nm scale 30 nm from the destination airport (see right).
