Nav Display (NAV)
The GNS 480 displays a track-based Horizontal Situation Indicator (HSI) view.
The Nav function is reached by pressing the NAV smart function key. The layout,
annunciations, and nav data are similar to Map mode. Distance to the destina-
tion is shown in the top left corner. Bearing to the destination is shown in the
top right corner. Current Ground Speed (GPS determined) is shown in the lower
left corner. The Estimated Time En Route from your current position to the next
waypoint is shown in the lower right corner. You may also select the categories
of Nav Data shown on the left side of the display. When vertical guidance is
provided, a vertical deviation indicator is shown on the left side of the display.
The CDI/VDI is driven by one of the following: GPS data if GPS CDI annuncia-
tion is selected or Nav radio data if LOC, VOR, or ILS annunciation is selected.
The HSI is always oriented to GPS track. In some cases, GPS track may not line
up perfectly with a VOR radial, but wind compensation is not necessary.
