Frequently asked

Are there any NOTAMs at KIOB right now?

Mount Sterling/Montgomery County has 6 active NOTAMs.

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.

More about KIOB

NOTAMs from the FAA NOTAM service. Times are UTC (Zulu). For planning and education only — NOTAM review is required preflight action under 14 CFR 91.103 and must be done through an official source.
