12.2 Sectorisation Principles
Training Objective
To understand how airspace is divided into sectors to ensure safe and efficient air traffic control.
Key Knowledge
- Sector design principles
- Vertical and lateral limits
- Traffic flow alignment
Operational Application
Controllers shall:
- Operate within defined sector boundaries
- Understand how sector design affects traffic flow
- Maintain awareness of adjacent sector activity
1. Overview
Sectorisation is the division of airspace into manageable units to distribute workload and maintain safe operations.
2. Core Content
2.1 Sector Boundaries
- Defined laterally and vertically
- Based on traffic flow and operational requirements
2.2 Traffic Flow Alignment
- Sectors are designed around major traffic flows
- Reduces crossing conflicts and coordination
2.3 Vertical Sectorisation
- Airspace may be split by level
- Allows separation of climb, cruise, and descent traffic
2.4 Dynamic Sectorisation
- Sector boundaries may change based on traffic demand
- Enables flexible workload management
3. Procedures
3.1 Application
- Controllers shall remain within assigned sector limits
- Coordination required when traffic approaches boundaries
4. Standards
- Sector boundaries shall be strictly observed
- Controllers shall maintain awareness of adjacent sectors
5. Notes
- Poor understanding of sector boundaries leads to coordination errors
- Sector design directly affects workload and complexity
