Coordination (ACC)

Coordination in an Area Control environment ensures safe and efficient transfer of aircraft between sectors and units.

Effective coordination allows: - Continuous separation - Predictable traffic flow - Reduced controller workload

---

Objectives

• Ensure seamless transfer between controllers
• Maintain agreed conditions (level, speed, route)
• Prevent conflicts at sector boundaries

---

Key Principle

Poor coordination creates conflicts — good coordination prevents them.
