Effective Time – FAA
Aeronautical information in the U.S. and its territories is generally effective on the designated effective date at 09:01 Coordinated Universal Time (UTC). The effective time applies to airspace, airways and flight procedures. It allows for implementation between 1:00 AM and 6:00 AM local standard time in the U.S. Local authorities may use a different time or date of implementation due to local operational considerations. Check NOTAMs and contact local ATC for information.
Effective Time – International, v2
International Civil Aviation Organization (ICAO) guidance specifies that aeronautical information should be effective on the designated effective date at 0000 Coordinated Universal Time (UTC). However, national and local authorities often use a different effective time to allow for implementation during the local night or at other times due to local operational considerations. When an effective time other than 0000 UTC is used, ICAO requires that it be published in the official Aeronautical Information Publication (AIP) of the country. Check NOTAMs for information.
