Conflict Detection and Resolution

JO 7110.65BB, Change 3, effective July 9, 2026 · Official text on faa.gov

Actively scan EDST information for predicted aircraft-to-aircraft and aircraft-to-airspace alerts.
When a conflict probe alert is displayed, evaluate the alert and take appropriate action as early as practical, in accordance with duty priorities.
Prioritize the evaluation and resolution of conflict probe alerts to ensure the safe, expeditious, and efficient flow of air traffic.
Note

Conflict probe alerts are based on approved radar separation. Conflict probe does not account for instances in which greater separation may be needed (e.g., non-standard formations, A380) or where reduced separation is permitted (e.g., 3 mile airspace).
When a conflict probe alert is displayed and when sector priorities permit, give consideration to the following in determining a solution:
1. Solutions that involve direct routing, altitude changes, removal of a flight direction constraint (i.e., inappropriate altitude for direction of flight), and/or removal of a static restriction for one or more pertinent aircraft.
2. Impact on surrounding sector traffic and complexity levels, flight efficiencies, and user preferences.
When the Stop Probe feature is activated for an aircraft, conflict probe for that aircraft must be restarted before transfer of control, unless otherwise coordinated.
Note

The requirement in subparagraph 13-1-2 e does not apply to aircraft entering a non EDST facility.
