Definition
A NOTAM contraction used to indicate Saturday and Sunday. It specifies that a condition, restriction, or service applies on weekend days.
Plain English
Short for 'weekend.' In a NOTAM, it tells you that whatever is being reported applies on Saturdays and Sundays.
Context Anchor
Seen in NOTAMs and other shortened aviation notices where space is limited.
Derivation
WKEND is a shortened form of “weekend.” The missing letters make it faster to write in compact aviation notices while keeping the meaning recognizable.
Why Pilots Care
Weekend-only restrictions or closures are common at smaller airports and military fields. Misreading WKEND can lead to arriving on a day when a runway, service, or facility is unavailable.
Intuition Check
WKEND does not mean “any days near the end of the week.” In this aviation notice context, it means Saturday and Sunday.
Example Sentence 1
The NOTAM stated the tower was closed WKEND, so the pilot planned to use the airport on a weekday instead.
Example Sentence 2
Maintenance is performed every WKEND.
