11.5 Equipment & System Failures

Training Objective

To manage failures of ATC systems or aircraft equipment.


Key Knowledge

  • Radar failure
  • Communication failure
  • Transponder failure

Operational Application

Controllers shall:

  • Apply alternative procedures when systems fail
  • Increase separation where required

1. Overview

System failures may reduce the ability to provide radar service.


2. Core Content

2.1 Radar Failure

  • Transition to procedural control if required

2.2 Communication Failure

  • Apply standard lost comm procedures

2.3 Transponder Failure

  • Identify aircraft using alternative methods

3. Procedures

3.1 Application

  • Controllers shall adapt to degraded operations

4. Standards

  • Separation shall be maintained using appropriate methods

5. Notes

  • System degradation increases workload significantly
