On December 30, 1999, the Fremont Military Operations Area (MOA) was officially renamed Airburst MOA and resized to optimize the operations of Buckley ANGB F-16. The MOA was divided into three constituent parts—A, B, and C—each with its own set of adjustments. Airburst A would keep its north, west, and east boundaries intact and moved its southern boundary north to leave out Cañon City and the Fremont County Airport. Airburst B would move its southern boundary east to run adjacent to the Fort Carson Restricted Area and would extend flight height from 500-feet above ground level (AGL) up to, but not including, FL 180 AGL. Airburst C would maintain the same boundaries and extend flight height from 500-feet AGL up to, and including, 8,500-feet mean sea level. Accordingly, the Instrument Flight Rules enroute high/low altitude charts, and the Sectional Aeronautical charts of Denver, Wichita, and Cheyenne, were adapted to reflect the new updates.
