04.5 Bottlenecks & Complexity Management
Training Objective
To identify and manage traffic bottlenecks and complexity within a sector.
Key Knowledge
- Bottleneck locations
- Conflict hotspots
- Complexity drivers
Operational Application
Controllers shall:
- Identify high-risk areas within the sector
- Apply proactive measures to reduce complexity
- Manage traffic before bottlenecks form
1. Overview
Bottlenecks occur where traffic converges, increasing the risk of conflict and workload.
2. Core Content
2.1 Bottlenecks
- Entry/exit points
- Crossing routes
- Level-off points
2.2 Complexity Drivers
- High traffic density
- Mixed climb/descent profiles
- Weather deviations
2.3 Conflict Hotspots
- Predictable areas of risk
- Require increased attention
3. Procedures
3.1 Complexity Management
- Early intervention shall be applied
- Traffic shall be organised before reaching bottlenecks
4. Standards
- Controllers shall maintain manageable workload at all times
5. Notes
- Late action leads to sector overload
