Optimising arrival spacing

Intelligent Approach is an arrival spacing tool that safely optimises runway capacity to improve operational resilience, deliver better on-time performance, reduce CO2 emissions and increase revenue

Customers can choose from the family of IA functional modules to best meet the unique needs of their operation. IA fully integrates into existing ATC systems and can be used in different environments to deliver benefits in many differing operational scenarios.

Intelligent Approach Modules

  • Dependent runway operations
  • Distance Based Separation
  • Time Based Separation
  • Pairwise Separation
  • Mixed Mode Operations

Intelligent approach has a standard module for segregated runway operations with distance based separation taking into account the airport’s wake vortex scheme. Further modules can be added to:

  • Improve separation
  • Increase modes of operation
  • Improve resilience

The following wake turbulence separation criteria can be applied:

  • ICAO: The standard wake turbulence model
  • RECAT (EU or US): Enables increased capacity by optimising wake separations
  • Pairwise: Enables significant capacity gain by taking account of individual aircraft wake
  • Custom: Any custom wake separation system approved for your airport
