Definition
To come together at, or move toward, a single point. In aviation, two aircraft, two flight paths, or two lines on a chart converge when they are travelling along courses that will meet at a common point if continued.
Plain English
Two things are heading toward the same point. If they keep going, they will meet.
Context Anchor
Seen in traffic descriptions, navigation, weather discussions, runway geometry, and any place where two lines, paths, or flows are described as coming closer together.
Derivation
From Latin convergere — con- (together) + vergere (to bend or incline). Literally 'to bend together.' That gives the aviation sense: paths bending toward one another until they meet.
Why Pilots Care
Establishes which aircraft must yield to prevent a mid-air collision.
Intuition Check
Do not read converge as simply “close.” Two things converge when they are getting closer together or heading toward the same place.
Example Sentence 1
ATC advised that traffic was converging from the right at the same altitude, so the pilot maintained visual contact and prepared to give way.
Example Sentence 2
The controller advised both pilots to watch for converging traffic near the airport.
