Cross Track Error
: The course deviation is shown on the map in the lower screen
center in tenths of a mile. An arrow shows you in which direction your course is from
your current position.
VNAV
: This displays required rate of descent data in the lower right corner of the map
when your descent to the destination airport pattern altitude (assuming 1000' PA) is 250
ft. per minute or greater. This box must also be checked to show VNAV information in
flight plans. For more information see
VNAV Concepts on page 37.
Lat/Long
: Your current position in latitude/longitude is shown in the bottom left corner
of the map.
Track History
: This feature leaves breadcrumbs (small dots) along the path flown.
Bold Course Line
: This function places a heavy black line on either side of the flight
plan course line in normal flight. The course line is green for the active leg and aqua for
all other legs of the flight plan.
Statute Miles
: This toggles all map distance data between statute miles and nautical
miles, as well as all velocity data from KPH to MPH.
North-Up Mode
: Plane will appear in the center of the screen, and it will rotate instead
of the map. Map screen will always have North at the top of the screen. Plane will have
swept back wings as a visual reminder that you are in North Up mode.
Day Mode
: Toggles between the day color set (light background) and the night color
set (black background).
Turn Coord
: Displays a circular Rate of Turn instrument in the lower left corner of the
map. The rate of turn, in degrees per minute, is shown digitally.
Rate/Climb
: Displays a Rate of Climb/Descent indicator in the lower right corner of
the map.
Tripometer
: Displays a Trip meter in the lower left corner that is the total distance
flown since last reset. To reset the trip odometer, tap Tools > Odometer/Trip meter>
Reset.
Show Map Range
: This shows which range is being displayed on the map. It displays
the distance from the aircraft icon to the EFIS arc/circle. It immediately sets context for
the distance between you and items being displayed on the map such as towers,
airports, airspace, and especially weather. The range in nautical miles (or statute if so
set) is shown in the upper left corner of the map under the flight timer. If this box is
unchecked, the range value will display briefly when changing zoom ranges and will
automatically hide after about five seconds to save screen real-estate.
Full HSI
: This will enable the HSI function to show on the screen and un-checking it
will remove the HSI display leaving only the EFIS or compass rose.
EFIS ARC
: This option places the aircraft icon towards the bottom of the map.
Unchecked this option places the aircraft icon in the middle of the moving map screen.
