Definition
A NOTAM contraction marking the first published version of a NOTAM, as opposed to an amended or cancelled one.
Plain English
Tells you this is the first version of a NOTAM that has been issued — nothing has been changed or replaced yet.
Context Anchor
Seen in FAA abbreviation lists, NOTAM contractions, flight planning information, and other aviation records where space is limited.
Derivation
Original comes from the Latin word origo, meaning source or beginning. That helps because original points to where something started or to its first form.
Why Pilots Care
Knowing whether a NOTAM is the original, an amendment, or a cancellation tells you which version is currently in force. Acting on an outdated NOTAM can mean missing a runway closure or other critical change.
Intuition Check
ORIG does not mean better, official, or more correct by itself. In this context, it means the first version or starting source being referred to.
Example Sentence 1
The briefing showed the runway closure NOTAM tagged ORIG, so we knew we were looking at the first published version.
Example Sentence 2
Check the ORIG date on the document to ensure you have the first version.
