Horizon Heading

The Horizon Heading is synchronized with the HSI and shows compass
headings in 30-degree increments on the Zero-Pitch Line. Horizon heading tick
marks and digits appearing on the zero-pitch line are not visible when they are
behind either the airspeed or altitude display. Horizon Heading is activated and
deactivated by pressing the HRZN HDG soft key.

Airport Signs

Airports Signs provide a visual representation of airport location and
identification on the synthetic terrain display. When activated, the signs appear
on the display when the aircraft is approximately 15 NM from an airport and
disappear at approximately 4.5 NM. Airport signs are shown without the
identifier until the aircraft is approximately 9 NM from the airport. Airport signs
are shown behind the airspeed or altitude display. Airport signs are activated and
deactivated by pressing the APT SIGNS soft key.
