Frequently asked

Are there any NOTAMs at KGTF right now?

Great Falls International Airport has 14 active NOTAMs, 1 of them affecting runways, 2 of high significance.

What is a NOTAM?

A Notice to Air Missions is a filed notice of a temporary condition a pilot needs to know about: a closed runway or taxiway, an out-of-service navaid or approach light, a crane near the approach path, or restricted airspace. Checking them is a required part of preflight action under 14 CFR 91.103.

What is an FDC NOTAM?

A Flight Data Center NOTAM is issued by the FAA rather than the airport, and covers regulatory matters: amendments to instrument approach procedures, changes to charted minimums, and temporary flight restrictions.
