NOTAM – Notice to Air Mission

A NOTAM (Notice to Air missions) is a notice issued by an aviation authority to provide information about any condition that may affect the safety of aircraft operations. NOTAMs are used to inform pilots of temporary changes to airport facilities, navigational aids, or procedures, as well as to advise of potential hazards such as closed runways or restricted airspace. Pilots and other professionals rely on NOTAMs, valid for a few days to a few weeks, that pinpoint specific timeframes for temporary changes in the airspace. The Federal Aviation Administration (FAA) issues them in the United States, while other aviation authorities around the world also have the power to do so.

NOTAMs, or Notices to Air Missions, are the essential whispers in the wind for pilots. They relay critical, real-time updates about the ever-changing landscape of the National Airspace System (NAS). Think runway closures, equipment glitches, airspace restrictions, even bird strikes – anything that could disrupt a smooth flight.

These concise bulletins aren’t just for commercial jets. From hobby drones to private planes, every airborne soul relies on NOTAMs to fly informed and avoid surprises. They’re the difference between a smooth landing and a near miss.

The NOTAM is in effect daily, during the hours of 12:00 to 23:59. The NOTAM advises pilots that Runway 13L/31R is closed for maintenance and should not be used during this time.
