Thumbnail Feature
The Thumbnail feature provides a small map depiction
that is overlaid in the upper left corner of the MX20
display. It provides for enhanced traffic and terrain
situational awareness when not specifically viewing traffic
or terrain related functions. For example, both traffic and
terrain situational awareness can be maintained while
viewing the Flight Plan Function.
The Thumbnail is shown in both a small and large
format, depending on the function currently being viewed.
The Thumbnail is typically presented in the larger format
when overlaid on a map. However, on some functions
where the Thumbnail would overlay critical information,
the smaller format is utilized.
The Thumbnail provides a fixed 5nm range view of
conflicting traffic and terrain. The range depicted by the
Thumbnail is not affected by the current zoom scale set
on the main map functions.
Traffic on Thumbnail
TIS, TAS, or TCAS traffic is shown on the Thumbnail in
the same symbology used within the Traffic Function.
ADS-B traffic is not shown on the Thumbnail. Any traffic
within sensor range and 5nm is shown, in addition to traffic
causing an amber Traffic Alert (TA) traffic. Note that the
MX20 supports one traffic sensor in any installation.
Terrain on the Thumbnail
Only “Red” terrain within the 5nm range is presented on
the Thumbnail. This correlates directly to terrain that is
rendered in red on the normal Terrain Function based on
the internal terrain database. External TAWS-based
terrain from the Goodrich Landmark is not shown on the
Thumbnail.
