Definition
A three-letter contraction used in NOTAMs, weather products, and aeronautical publications to indicate Saturday, the seventh day of the week.
Plain English
Just a short way of writing 'Saturday' in official aviation messages.
Context Anchor
Seen in aviation schedules, airport information, and FAA abbreviation lists when days of the week are shortened.
Why Pilots Care
NOTAMs and airport facility information often state when services, runways, or airspace restrictions apply by day of the week. Misreading the day code can lead to arriving when a fuel service is closed or flying into active restricted airspace.
Intuition Check
In aviation publications, SAT almost always means Saturday. Don't confuse it with other uses of 'SAT' such as Static Air Temperature, which appears in performance and avionics contexts — the surrounding text makes it clear which is meant.
Example Sentence 1
The NOTAM stated that the control tower would be closed SUN through SAT during the holiday week.
Example Sentence 2
Check the NOTAMs for SAT and SUN operations at the airport.
