Airspace Information on the Map
When a special-use or controlled airspace boundary
appears on the Map Display, the pilot can quickly retrieve
information (such as floor/ceiling limits and controlling
agency) directly from the map.
Viewing airspace information for an on-
screen special-use or controlled airspace:
1) Use the panning function ('Map Panning' in this
section) to place the target pointer on an open
area within the boundaries of an airspace. If
the area is congested and it is difficult to select
an open area, the pilot may need to zoom in or
press the CLR Key to make the selection easier
(Figure 3-14).
