GPS 400 Pilot’s Guide and Reference190-00140-60 Rev. HSECTION 2NAV PAGES2-252.9 VERTICAL NAVIGATION PAGEThe GPS 400’s Vertical Navigation Page (the last NAVpage, see Figure 2-49) allows the pilot to create a three-dimensional profile which guides the pilot from thepresent position and altitude to a final (target) altitude ata specified location. This is helpful when the pilot wouldlike to descend to a certain altitude near an airport orclimbing to an altitude before reaching a route or direct-to waypoint (Figure 2-50). Once the profile is defined,message alerts and additional data on the Default NAVPage and the Map Page provide guidance to the pilot.Figure 2-49 VNAV (Vertical Navigation) Page651 43287 9Target Altitude1Target Distance2Altitude Reference (AGL or MSL)3Target Reference4Vertical Speed Desired5Vertical Speed Required6Current Page Group7Number of Pages in Current Page Group8Position of Current Page within CurrentPage Group9NOTe: To use the vertical navigation features,ground speed must be greater than 35 knotsand the pilot must be navigating to a direct-todestination or using a flight plan.VERTICAL NAVIGATION PROFILEVERTICAL SPEED REQUIREDDISTANCE TO TARGETTIME AND DISTANCETO PROFILETARGET ALTITUDEAND POSITIONAIRPORTCURRENT ALTITUDEAND POSITIONFigure 2-50 Vertical Navigation ProfileCreating a vertical navigation profile(Figure 2-50):1) Press the small right knob to activate thecursor.2) Turn the large right knob to highlight thetarget altitude field.3) Turn the small and large right knobs to selectthe target altitude (Figure 2-51) and press theENT Key.Figure 2-51 Target Altitude Field Selected
