The following section of the manual describes the appearance of
the SN3500 display and identifies each functional element. Detailed
descriptions of these elements and a tutorial guide to their use are
presented in later sections.
Display Areas
The primary display area shows either a 360-degree FULL view or a
70-degree ARC view, as indicated by the white compass ring. The
white airplane or triangle represents the aircraft’s current position.
The primary display area may also depict the current GPS flight
plan, airports, navaids, intersections, airspace, traffic, FIS-B datalink
weather and/or Stormscope® data if the map feature has been
enabled. Several indicators (see below) are also presented within

Figure 2-2 Display areas
The upper display area presents data from the selected course
navigation instrument. The data displayed depends upon the
navigation source (VOR/DME or GPS) but it will generally include
bearing, distance, and ground speed, if available. The upper
display area also includes information on the map status, WX-500
Stormscope® status (if installed), and an annunciation on whether
the VOR NAV display is currently receiving either a localizer or a full
ILS (localizer/glideslope) signal.
The lower display area presents the numeric data associate with the
two bearing pointers. This includes the NAV source, bearing and
distance (if available). The right section of this area contains a
display of the marker beacon lights if configured. The left section
includes GPS annunciators, if configured.
Indicators
Several different symbols, or indicators, are used in each of the
display areas. These are described below:
