Far left, Map Page opening screen. Center, zoomed to 100 nautical miles
and right, zoomed to 6 nautical miles. (Note that the four data boxes ap-
pearing in the bottom of these images are
on by default. They have been
turned off in most of the following images for the sake of clarity.)
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its cov-
erage area and the amount of mapping detail shown. There are 39 available
map zoom ranges, from 0.02 nautical miles to 4,000 nautical miles.
AirMap's high resolution screen makes it possible to display aeronautical
chart features that look like the "real thing." If you're familiar with sectional
charts, you will instantly recognize items such as obstacles, VORs, special
airspaces, paved and unpaved airports and more. As you zoom in closer,
you'll see Class B airports appear at a fairly wide zoom. Zoom in closer and
Class C and D airports appear, as well as restricted airspaces. At closer
zooms still you can even see Class C airspace borders around airports.
If you're using only the factory-loaded background map, the maximum
zoom range for showing additional land map detail is 6 nautical miles. You
can continue to zoom in closer, but the map will simply be enlarged without
revealing more map content (except for a few major city streets.) Load your
own high-detail custom map made with MapCreate, and you can zoom in to
0.02 nautical miles with massive amounts of accurate map detail.

At left, arterial streets appear at the 4 nautical mile zoom range. At 1
nautical mile, minor streets appear, along with square dots represent-
ing Points of Interest. Right, at the 0.4 nautical mile zoom, you can see
an interstate highway with an exit, major and minor streets as well as
Point of Interest icons for two hotels and two restaurants.
