Hide Benign Obstacles:
Select to hide Obstacles that range from 200' to 400' AGL.
Nuclear Power Plants, Sport Stadiums
: You can also choose to display loiter-
sensitive objects such as stadiums and nuclear power plants, and may optionally display
the 3 nautical mile veil that surrounds them.
Urban Areas
: Allows the user to see the outer boundaries of urban areas drawn in
yellow as on a sectional chart.
APP Freq Tags
: Data Tags are approach/departure frequency tags that appear around
some of the higher density airspace. When zoomed out, there is a small green dot on
which you can tap to see the frequency. When zoomed in, the dot is replaced with a
rectangular box in which the frequency is displayed.
MaxNav Sectionals:
Displays US Sectional Chart and may warn the user to disable
duplicate items that the user may have also checked for display such as, Cities,
Highways, Terrain, water etc. for the clearest view of the sectional possible.
Low Enroute Charts:
Displays US IFR Low Enroute Charts and may warn the user to
disable duplicate items that the user may have also checked for display such as, Cities,
Highways, Terrain, water etc. for the clearest view of the enroute chart possible.
High Enroute Charts:
Displays US High Altitude charts with Jet Airways. and may
warn the user to disable duplicate items that the user may have also checked for display
such as, Cities, Highways, Terrain, water etc. for the clearest view of the sectional
possible.
Terrain Elevations
: Choose whether to display terrain. Terrain is depicted in colored
tiles that denote elevation of a point within that tile. The size of each tile is 1 mile
square (high resolution at close zoom levels). If the MaxNav™ upgrade has been
purchased, the terrain tiles are 180 meters square, resulting in dramatically sharper
terrain rendition.
Terrain resolution increases as the zoom level is changed from wide to close. This is
done to keep the map performance optimized. Terrain color is also adjustable. You can
choose from light, medium, or dark. In the dark setting, lower terrain altitude will be
dark green.
In the light setting the low altitude terrain will be very light green. Terrain color
shading transitions from green to orange to brown at higher altitudes to finally white,
making the mountain tops appear white. You may wish to use a lighter terrain color
during the daylight hours if you are flying in an area with low elevations to improve
contrast. In higher elevations it is often better to use a darker color.
