Definition
A situation in which an aircraft enters, or is projected to enter, airspace where it is not authorized to operate, or where its presence creates a loss of required separation from other traffic, restricted areas, or special use airspace.
Plain English
When an aircraft is — or is about to be — somewhere in the sky it shouldn't be, either because it's too close to other traffic or because it's entering airspace it doesn't have permission to be in.
Context Anchor
Seen in air traffic control and flight-planning contexts when a proposed or current route is checked against active airspace areas.
Derivation
Conflict comes from a Latin idea meaning “to strike together.” In aviation, it does not mean an argument; it means two planned uses of the sky do not safely fit together at the same time.
Why Pilots Care
Unresolved airspace conflicts can force sudden maneuvers or lead to mid-air collisions.
Intuition Check
Do not read “conflict” as a disagreement between people. Here it means the aircraft’s path and an active airspace area overlap in a way that needs to be resolved.
Example Sentence 1
ATC issued an immediate turn to resolve an airspace conflict with traffic departing the parallel runway.
Example Sentence 2
The crew received a TCAS resolution advisory after an airspace conflict developed with a crossing flight.
