06.1 Vertical Control Principles

Training Objective

To establish the principles governing vertical control in an en-route environment.


Key Knowledge

  • Vertical separation minima
  • Climb and descent profiles
  • Interaction with lateral control

Operational Application

Controllers shall:

  • Maintain vertical separation at all times
  • Anticipate level changes and conflicts
  • Integrate vertical and lateral strategies

1. Overview

Vertical control involves managing aircraft altitude to ensure separation and support traffic flow.


2. Core Content

2.1 Vertical Separation

  • Standard separation: 1000 ft (RVSM)
  • Increased separation outside RVSM where applicable

2.2 Vertical Profiles

  • Aircraft climb and descent rates vary
  • Performance affects conflict timing

2.3 Integration with Lateral Control

  • Vertical and lateral solutions may be combined

3. Procedures

3.1 Monitoring

  • Controllers shall monitor climb and descent continuously
  • Deviations shall be identified early

4. Standards

  • Vertical separation shall not be infringed

5. Notes

  • Vertical conflicts develop quickly if unmanaged
