Effective on February 25, 2021, all Sectional Aeronautical, VFR Terminal Area (TAC), VFR Flyway Planning, VFR Aeronautical, and Helicopter Route Charts will be updated every 56 days.
Aero App for iOS, Android and Windows version 1.2012 and higher supports this 56-day FAA charting change.
To ensure compatibility with older versions of the Aero App, i.e. versions prior to 1.2012, 28-day VFR Charts will be made available on Aeroapp.info.
