1.7 Control Philosophy

1.7.1 General

Radar control is based on anticipation, planning, and continuous monitoring.

The Approach Controller shall manage traffic proactively, ensuring that conflicts are identified and resolved before they develop.


1.7.2 Predictive Control

Radar control is predictive in nature.

The Approach Controller shall:

  • Anticipate aircraft trajectories and future positions
  • Identify potential conflicts in advance
  • Issue control instructions early
  • Avoid reactive or last-minute interventions

1.7.3 Traffic Planning

The Approach Controller shall:

  • Develop and maintain a mental traffic picture
  • Plan sequencing and spacing in advance
  • Integrate arrivals and departures efficiently
  • Adjust plans dynamically based on traffic conditions

Effective planning reduces workload and prevents conflict.


1.7.4 Continuous Monitoring

The Approach Controller shall:

  • Monitor all aircraft under control at all times
  • Verify compliance with instructions
  • Detect deviations or unexpected behaviour
  • Update the traffic picture continuously

Loss of monitoring may lead to loss of separation and shall be prevented.


1.7.5 Workload Management

The Approach Controller shall:

  • Manage traffic complexity within safe limits
  • Simplify control when workload increases
  • Prioritise critical tasks
  • Avoid overloading themselves or the frequency

Traffic shall not be accepted beyond the controller’s capacity to manage safely.


1.7.6 Decision Making

The Approach Controller shall:

  • Make timely and decisive control actions
  • Prioritise safety and separation
  • Adapt to changing situations
  • Maintain control of the traffic situation at all times

1.7.7 Radar vs Tower Control

Radar control differs from aerodrome (tower) control in that:

  • Multiple aircraft are controlled simultaneously
  • Separation is applied in three dimensions
  • Control is based on predicted aircraft positions
  • Traffic flow management is continuous and dynamic

1.7.8 Key Principle

The Approach Controller shall:

  • Plan ahead
  • Act early
  • Monitor continuously

Radar control shall be proactive, structured, and controlled at all times.
