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.

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.
