During route navigation, it is sometimes desirable to navigate a specified distanceaway from the ‘active leg’ to help avoid certain airspaces or regions. The GNC 250’sparallel track feature will automatically guide you along a selected offset from theactive leg.To use offset navigation, or parallel track:1. Press R and use O to display the route catalog page.2. Use K to display route 0 (parallel track can only be used on the active route).3. Press C twice and use O to highlight the parallel track value field.4. Use K and O to enter the desired distance and direction (R or L) from the leg.5. Press E to accept.It is important to note that offset navigation is only available on route navigation,not direct-to navigation. When offset navigation is activated, an ‘Offset nav in effect’message will be displayed with the distance and direction noted on the route catalogpage for route 0. If you enter an offset which causes a leg to be reversed, you’ll beinformed with the message ‘Ofst too big for rte’. If you change the active route in anyway or perform a direct-to, you’ll be informed with an ‘Offset nav cancelled’ message.66APPENDIX ASUA SettingsAIRPLANEDEPARTURE WAYPOINTOFFSETDISTANCEARRIVALWAYPOINTParallel TrackEnter parallel track value after route activation.SECTION5 ROUTESParallel TrackOffset Navigation
