What is a NOTAM's duration?

NOTAMs are notices about temporary conditions that affect flight safety, and they are issued with a finite validity window. They’re not meant to stay in effect forever; the information must be time-bound so pilots know how long it remains current. In practice, a NOTAM’s duration is limited, typically not exceeding 90 days; if the condition continues beyond that, a new NOTAM is issued or the notice is updated. A NOTAM with no end date would leave pilots relying on information that could become outdated, so time-bound validity is essential. This is why describing a NOTAM as temporary in nature, with an upper limit around 90 days, best fits.
