Definition
A NOTAM contraction meaning 'from facility,' used to indicate a bearing or radial measured outbound from a navigation aid such as a VOR or NDB.
Plain English
A short way of saying 'measured outward from the navigation station.' It tells you the direction is going away from the facility, not toward it.
Context Anchor
Seen in NOTAMs and FAA notices that describe where something is located or where a condition applies.
Why Pilots Care
Knowing whether a bearing is from or to a facility changes which direction you actually fly. Reading FFAC correctly prevents flying the reciprocal heading by mistake.
Intuition Check
“Facility” does not mean only a building here. In this context, it can mean the named aviation point or service the notice uses as its reference.
Example Sentence 1
The NOTAM described the closed airway segment as a radial FFAC the VOR, beginning 12 miles out.
Example Sentence 2
Pilots scanning the list confirmed the taxiway closure was listed FFAC for accuracy.
