Finally!!! As per AIRAC AMDT 04/20 Effective Date 23 APR all Military TMAs base altitude is corrected to 1000’ Above SFC and not MSL as it was declared incorrectly for more than a decade. This is a major correction following the altitude correction of the civil TMAs that was published last June 2019.

General Aviation friendly! A clear 1000’ above surface in class G airspace. Finally like the rest of the world.
