Thispage may be quickly selected from ANY page by usingthe CLR key.Active Leg of Flight Plan,or Direct-to DestinationUser-selectable DataFields(all four corners)Course DeviationIndicator (CDI)First Page in NAV GroupBearing pointer to thecurrent TO waypointTo select the NAV group and display the DefaultNAV Page, press and hold CLR.The default NAV Page provides a “look ahead”map display with your present position at the bottomcenter of the page. The top of the page displaysdesired track (DTK), ground track (TRK) and distanceto destination waypoint (DIS). The bottom of the pageindicates ground speed (GS), active to/from waypoints(only active to, for a direct-to destination) and esti-mated time en route. A graphic course deviationindicator (CDI) also appears at the bottom of the page.Unlike the angular limits on a CDI coupled to a VORor ILS receiver, full scale limits for this CDI are definedby a GPS-derived distance (2.0, 1.0 or 0.3 NM). Bydefault, the CDI scale automatically adjusts to thedesired limits based upon the current phase of flight:en route, terminal area or approach.NOTE: Approaching the FAF, the GNS 500W-seriesunit automatically rescales in an angular fashion. Thisallows the LPV approach to be flown identically to astandard ILS. At 2.0 NM from the FAF, CDI scaling istightened from 1.0 to the angular full scale deflectiondeifned for the approach.You may also manually select the desired scale set-ting as outlined in Section 9.The graphic CDI shows your position at the centerof the indicator, relative to the desired course (themoving course deviation needle). As with a traditionalmechanical CDI, when you’re off course simply steertoward the needle. The TO/FROM arrow in the centerof the scale indicates whether you are heading to thewaypoint (an up arrow) or if you have passed thewaypoint (a down arrow).The following symbols are used — on theDefault NAV Page directly above the graphicCDI — to depict the “active leg” of a flightplan or direct-to.Direct-To a WaypointCourse to a Waypoint, or DesiredCourse between Two WaypointsRight Procedure TurnLeft Procedure TurnVectors-To-FinalDME Arc to the leftDME Arc to the rightLeft-Hand Holding PatternRight-Hand Holding PatternDefault NAV Page190-00357-00_0B 500W Pilot Guide30 30 9/7/2007 3:10:00 PM
