03.3 Separation Responsibility

Training Objective

To define ownership and application of separation.


Key Knowledge

  • When ATC is responsible for separation
  • Transfer of responsibility
  • Pilot vs controller responsibility

Operational Application

Controllers shall:

  • Maintain separation between controlled aircraft
  • Ensure separation is transferred correctly
  • Monitor until responsibility is transferred

1. Overview

Separation responsibility lies with the controller once radar control is established.


2. Core Content

2.1 Controller Responsibility

  • Applies to all identified aircraft under control
  • Continues until transfer of control

2.2 Transfer of Responsibility

  • Occurs at defined coordination points
  • Must be clearly established

2.3 Pilot Responsibility

  • Applies in specific cases (e.g. visual separation if approved)

3. Procedures

3.1 Handover

  • Separation shall exist at the point of transfer
  • Receiving controller assumes responsibility upon acceptance

4. Standards

  • Controllers shall not transfer conflicted traffic
  • Separation must be assured prior to transfer

5. Notes

  • Assumptions during handover are a major risk factor
