IFR Enroute High Altitude Chart

502. IFR ENROUTE HIGH ALTITUDE CHART

Front Panel

Figure 5-1 is a view of the front panel of your Enroute High Altitude Charts. Notice the arrows

in each corner give you a convenient reference as to which side of the sheet your desired chart is

printed. The most important information on the panel is the date the chart becomes effective and

when it expires. Never conduct IFR operations with an invalid chart. Major changes to the

airway structure and procedures are scheduled by the FAA to coincide with the 56-day chart

revision cycle. NOTAMS should be consulted for minor changes, which occur during the

period.

A listing of Prohibited, Restricted, and Warning Areas depicted on the charts begins on the front

panel. The information for each area repeats the most important parts of the AP/1A entry:

effective altitude, times used, and controlling agency. On the charts, Special Use Airspace is

shown only by an outline of the area and its identification; further information, if required in

flight, can be obtained from the front/rear panels. Only Special Use Airspace in the High

Altitude Structure (i.e., 18,000 feet MSL and above) is depicted on the High Charts (Figure 5-1).
