AUP/UUP - Airspace Use Plan / Updated Use Plan

The Airspace Use Plan (or AUP) comprises an Airspace Management (ASM) message notifying the daily decision of an Airspace Management Cell (AMC) on the temporary allocation of the airspace within its jurisdiction. AUPs are issued at least on a daily basis. An AUP message can be updated or superseded through an Updated Airspace Use Plan (UUP).
