Benefits of GBAS

GBAS is a 21st-century solution to replace or supplement Instrument Landing Systems (ILS). GBAS will overcome many ILS technical and operational limitations which currently constrain flight path flexibility and airport throughput.

GBAS can provide significant safety capacity, efficiency and environmental benefits for airlines, airports and air navigation service providers.

For airlines it delivers:

  • improved safety
  • less flight disruptions and associated cost caused by ILS interference
  • minimal pilot training.

Airports benefit from:

  • improved airport capacity from accurately guided, simultaneous operations to parallel runways and reduced runway exit times
  • flexibility in GBAS station location, unlock valuable airport land and alleviate traffic restrictions which are otherwise required to protect ILS signals from interference sources
  • improved airport access, even where ILS cannot be installed for terrain or economic reasons.

Air navigation service providers can obtain:

  • reduced traffic delays and congestion as a result of more  efficient and predictable approaches
  • reduced capital investment cost and lower ongoing maintenance, as one GBAS covers all runways at an airport compared to one ILS installation required per one runway end
  • easier and less frequent flight inspections than ILS
  • continued operations even during routine flight inspection or airport works.
