aircraft altitude. Terrain that is shown below the horizon line is below the aircraft altitude.
Horizon Heading
A heading scale may be displayed on the PFD horizon line, if selected by the pilot. The heading marks
are spaced in even 30 degree increments and are presented just above the horizon line with tic marks
that intersect the horizon line. The horizon heading will correspond to that presented by the HSI.
Because the horizon heading is only displayed in 30 degree increments, it should only be used for
general heading awareness and not be used to establish the aircraft heading.
Airport Signs and runway highlight
If APTSIGNS is selected, a “sign post” along with a representation of the runways will be plotted on the
SVS display for nearby airports that are contained in the G1000 airport database. The signpost will
become visible when you are within approximately 15nm of the airport. The text identifier for the airport
will be displayed inside the airport sign when the aircraft reaches approximately 8 nm from the airport.
Once the aircraft reaches approximately 4.5 nm from the airport, the airport sign will be removed but the
runways presentation will remain. If an approach to a specific runway has been loaded and activated,
that runway will be highlighted on the SVS display.
When on an approach, the highlight for the approach runway will be considerably larger than “normal” to
assist in visually acquiring the runway. The oversized highlight will automatically shrink around the
runway depiction so that the runway is proportionally displayed when the aircraft is within approximately
½ nm of the threshold. Runway highlighting is displayed even if APTSIGNS are turned off.
