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 onscreen 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).
