![]() ![]() Top of Descent indicated on the GTN 750 (right) and the VDI and VNAV altitude for LIPTE shown on the G500/600 (left). These features appear on the G500/600 starting with software version v7.30 and on the G5 with software v5.50.įig 2. Note also the white diamond above that, which is the location (above us) of the GPS glidepath. It also shows the VDI bar with a magenta V on top, indicating this is a VNAV slope, and a magenta chevron showing the sloped course is above us. The right picture in Figure 2 shows the TOD on the GTN 750 there, while the left picture of the PFD portion of the G500 or G600 shows the target altitude of 6000 feet for LIPTE. The slope starts at a defined point called the top of descent (marked TOD on the map), and may also display a BOD (bottom of descent). In Figure 1 the procedure altitudes are shown for an LPV approach to Rwy 11L at KTUS. The altitudes with attached slopes are connected to flight plan waypoints, and can be entered either by procedures (step-down altitudes on an arrival or approach, for example) or entered manually. It will also send digital pitch commands directly to a digital autopilot to track that slope. So what exactly is a baro-VNAV system? In a nutshell, it creates sloped courses attached to baro-corrected altitudes at specific waypoints the slopes are displayed on a VDI (vertical descent indicator) on an appropriate EFIS. Again, this system is used only for descents. Now, with v6.50 software, Garmin is bringing this capability to their touch screen navigators: the GTN 650/750. An LPV approach to Tucson is shown here, with step down altitudes on each flight plan waypoint. It does not store any personal data.Figure 1.
