WATAS Wake Vortex Separation Advisory

Trial available   Sign-up today

About the product:

WATAS is an indispensable decision tool to any Tower, providing Tower controllers with real-time visualized wake vortex advisory, for ensuring highest runway capacity, throughput, performance and safety Using IATAS’s patent-pending technologies, WAVO offers the highest wake vortex separation precision, automatically applying separation minima regulations (ICAO/FAA/NATS) for each runway operation while taking into account additional configurable safety buffers, environmental and operational procedures.

WATAS provides airports and ANSPs cost effective and intuitive solution to increase overall airport capacity, with immediate operational ROI.

Operational Benefits and Features

  • • Visualise regulated separation vs. actual separation to give the controller selectable separations
  • • Maximise runway and overall airport capacity without infringing on safety
  • • Lower the human error factor in calculating and applying the proper in wake vortex separation
  • • Use crossing or diverging runways for multiple operations without risking vortex separation errors/miscalculations
  • • Be assured each and every operation adheres to the applicable vortex separation regulation
  • • Can be used at any given junction of any runway configuration
  • • Can work in conjunction with SMIX/SMGCS for optimal accuracy
  • • Works with remote towers

Visuals / alerts (partial list):

  • • Visualise wake area, strength and duration for each operation
  • • Visualise when next operation can take place for each aircraft at or near a runway (support for partial runway operation)
  • • Capacity impact based on breaking action, gusts, crosswinds, maintenance windows, emergency incident
  • • Runway safety report, possible issues and conflicts
  • • Junctions overload, HOTSPOTS, alternate routing per flight (pre-planning)
  • • Partial runway and full runway maintenance windows

Parameter Control (partial list):

  • • Separation minima regulation type (ICAO / FAA / NATS / custom)
  • • Configurable added buffers per aircraft class type (support for lower/high medium type, as well as custom)
  • • Configurable added buffers per point / junction based on dependent runway configurations
  • • Configurable added buffers per runway operation type

Optional Add-ons

  • • SMIX/SMGCS interface


  • • SWIM Compliant using AIXM for interoperability and adherence to AIRM. Registered within SESAR SWIM registry.
  • • Supports differences between regulators (ICAO / EC/ FAA / NATS)
  • • Wake vortex separation minimas (ICAO, NATS, FAA)



  • • Realtime support through IATAS Int'l Operations Center (IOC)
  • • Phone, video conferencing and remote desktop support Mon-Fri 08:00-21:00 UTC

Ordering and Supply

  • • Turn-key, most functionality is OUT OF THE BOX
  • • Supply of base system within 8 weeks from receiving all required airport data and information (depending on airport size and configurations).
  • • Delivery of optional add-ons related to integration with external systems depends on availability of your technical staff for integration after initial delivery phase.
  • NOTE: An initial wake vortex analysis may be needed prior to the set-up
