Definition
A NOTAM contraction indicating that the information or change being published takes effect at the moment the notice is issued, with no future start time. Used when an airspace, facility, procedure, or condition change is active right now and pilots must comply from this point forward.
Plain English
It means the notice is in force from the moment it is published. There is no waiting period and no scheduled start time — pilots are expected to act on it straight away.
Context Anchor
Seen in NOTAMs and other aviation notices when a change starts right away.
Why Pilots Care
Pilots must act on WIE notices without delay, as they affect current flight operations or airport conditions.
Intuition Check
WIE does not mean soon or when convenient. It means the notice takes effect now.
Example Sentence 1
The NOTAM stated that Runway 27 was closed WIE due to a disabled aircraft on the runway.
Example Sentence 2
Controllers issued the new altitude restriction WIE during the approach.
