Where is information about a taxiway closure found?

Information about a taxiway closure is primarily found in the NOTAM (D) distribution. NOTAMs (Notices to Airmen) are essential for alerting pilots to time-sensitive information regarding the status of airports, runways, taxiways, and other aviation infrastructure. NOTAM (D) specifically caters to the distribution of information that is deemed essential for the operational safety of flights, including any closures or significant changes to taxiway status.

For pilots, keeping track of NOTAMs is critical, especially for those flying under Instrument Flight Rules (IFR), as these notices ensure that they are aware of any disruptions that could impact their approach, landing, and ground handling. Checking NOTAMs before a flight is a standard procedure to ensure that pilots have the most accurate and up-to-date information regarding the airports they will be using.

While FDC NOTAMs provide information on changes to instrument approach procedures, Aeronautical Information Publications contain a broader range of data including charts and regulations, and Terminal Procedures Publications specifically entail procedural information for instrument approaches and departures, the most direct and relevant source for taxiway closure alerts remains the NOTAM (D) distribution.
