04.4 Flow Control Measures

Training Objective

To apply techniques that regulate traffic flow and reduce complexity.


Key Knowledge

  • Speed control
  • Vectoring
  • Level restrictions
  • Direct routings

Operational Application

Controllers shall:

  • Use appropriate techniques to regulate traffic flow
  • Apply minimal intervention required to maintain control

1. Overview

Flow control measures are used to maintain safe and efficient traffic movement.


2. Core Content

2.1 Speed Control

  • Primary tool for minor adjustments

2.2 Vectoring

  • Used to resolve conflicts or manage spacing

2.3 Level Restrictions

  • Prevent conflicts and manage flow

2.4 Direct Routing

  • Improves efficiency but may increase complexity

3. Procedures

3.1 Application of Measures

  • Controllers shall select the simplest effective solution
  • Actions shall not create secondary conflicts

4. Standards

  • Safety shall not be compromised for efficiency

5. Notes

  • Overuse of vectoring increases workload
