Definition
A NOTAM contraction used in place of the word 'over.' It indicates that something is positioned above, passing above, or located on top of a referenced point, area, or feature.
Plain English
A short way of writing 'over' in NOTAMs and aviation messages, used to say something is above or on top of a place.
Context Anchor
Seen in NOTAMs, airport notices, and other space-limited aviation text where common words are shortened.
Derivation
“Over” comes from an old English word meaning above or across. That helps because aviation use keeps those same basic ideas: something may be over an airport, over a runway, or over a stated limit.
Why Pilots Care
NOTAMs are written in heavily abbreviated form. Recognising OVR as 'over' lets a pilot read a NOTAM quickly and correctly understand spatial relationships described in it.
Intuition Check
Do not read OVR as the name of a system, route, or procedure. In this context, it simply means “over,” with the exact sense supplied by the rest of the notice.
Example Sentence 1
The NOTAM read 'TFR OVR STADIUM,' meaning a temporary flight restriction was in place over the stadium.
Example Sentence 2
Turbulence was reported OVR the ridge line during the flight.
