Definition
A NOTAM contraction meaning daily — used to indicate that a condition, restriction, or activity occurs every day, typically during specified hours.
Plain English
Shorthand for 'daily.' When you see DLY in a NOTAM, it means the listed event happens every day.
Context Anchor
Seen in NOTAMs, airport notices, and other aviation schedules where space is limited.
Why Pilots Care
Knowing that something is in effect daily — rather than one time only — affects flight planning. A daily closure means you must plan around it on any day you intend to fly there.
Intuition Check
Do not read DLY as daylight. DLY means daily: every day in the listed period.
Example Sentence 1
The NOTAM showed runway 09 closed DLY 0600–0900 local for construction.
Example Sentence 2
Pilots should check the DLY fuel availability notice before planning a stop at the airport.
