Capture the glideslope as you would an ILSglideslope.7. As you cross LOTKE, the destination sequencesto the MAP (“RW31”, the runway threshold).With the needle on the external CDI (or HSI)centered, fly toward the MAP, observing thealtitude minimums dictated by the approachplate.8. When viewing the Map Page, you’ll notethat the final course segment is displayedin magenta (the active leg of the flight planalways appears in magenta).9. As you approach the MAP, a waypoint message(“DTK 312° x S”) appears on the bottom ofthe screen.10. Once the unit crosses the MAP (defined asthe runway end waypoint), sequencing willbe suspended. Prepare the aircraft for missedapproach operation. Press the OBS key tosequence to the Missed Approach procedure.11. Fly the guidance provided by the unit to theARTTY intersection and hold.LNAV/VNAV and LNAV Approaches with Advi-sory Vertical GuidanceGPS approaches with vertical guidance may beeither LNAV/VNAV or LNAV approaches with advisoryvertical guidance. LNAV-only approaches with advi-sory vertical guidance only have LNAV minima listedon the bottom of the approach plate. The glidepath istypically denoted by a light dashed line on the verticalprofile (Jeppesen only) with an associated glidepathangle (usually in the 3.00° range). These approachesare indicated with “LNAV+V”.For approaches with LNAV/VNAV minimums,those will be controlling. For LNAV approaches withadvisory vertical guidance, the LNAV minimums willbe controlling. Approaches confirmed as LNAV/VNAVapproaches in the Jeppesen NavData are indicatedwith an L/VNAV annunciation. At the time of thispublication, not all of the LNAV/VNAV approacheshave been identified as such in the Jeppesen NavData,therefore some LNAV/VNAV approaches may still beidentified with LNAV+V annunciation.NOTE: When flying LNAV approaches withadvisory vertical guidance, the vertical guidancemay be ignored and descent is accomplished inaccordance with published step-down altitudesand MDA.Points to Remember for All Approaches• The GNS 400W-series unit is designed to comple-ment your printed approach plates and vastlyimprove situational awareness throughout theapproach. However, you must always fly an approachas it appears on the approach plate.• The active leg (or the portion of the approachcurrently in use) is depicted in magenta on theMap Page. As you fly the approach, the 400W-series unit automatically sequences through eachleg of the approach unless “SUSP” appears abovethe OBS key. “SUSP” indicates that automatic
