09.4 ACC ↔ ACC (External) Coordination
Training Objective
To coordinate aircraft between different FIRs.
Key Knowledge
- FIR boundaries
- Letters of Agreement (LOA)
- Coordination points
Operational Application
Controllers shall:
- Coordinate aircraft in accordance with LOAs
- Ensure compliance with boundary conditions
- Maintain separation until transfer
1. Overview
External coordination ensures safe transfer between FIRs.
2. Core Content
2.1 Coordination Points
- Defined boundary fixes
- Transfer occurs at agreed points
2.2 LOA Compliance
- Defines:
- Levels
- Routes
- Speeds
3. Procedures
3.1 Coordination
- Controllers shall comply with LOA requirements
- Deviations shall be coordinated in advance
4. Standards
- Aircraft shall meet agreed boundary conditions
5. Notes
- Failure to follow LOA leads to coordination breakdown
