Change in EST Usage in Notice to Airmen (NOTAM)

This document provides clarity and guidance regarding the use of the contraction "EST", which stands for "Estimated", when appended to the end of validity time in a NOTAM. The FAA is taking this action to align NOTAM policy with International Civil Aviation Organization (ICAO) standards and recommended practices.
