Level of Service Assessment

CAST Terminal is the recommended simulation tool to check the compliance of terminal facilities with the desired Level of Service. CAST Terminal extensively has been used by IATA Consulting in projects with the focus on Level of Service Assessments.


Airports around the world strive to offer their passengers a pleasant journey. All optimization measures should begin with a fair-minded and unbiased analysis of the strengths and weaknesses of the passenger terminal. International organizations like IATA provide a framework to compare key performance indicators like waiting time and available space with. This allows assessing the level of service at an airport and comparing it with industry standards.

Facts & Benefits

  • Simulation of all terminal facilities
  • Waiting time and space assessment
  • Application for IATA or user-defined service standards
  • Analysis of current and future traffic
  • Realistic visualization of results
  • Detection of bottlenecks
  • Test of mitigation measures
  • Well-founded decision support

Airport simulation is a future proof approach


In contrast to on-site observations, it not only allows to assess the level of service of today’s operation but also analyzes the effect of planned infrastructure or operational improvements.


Airports that have built a simulation model appreciate it as a versatile tool: A reliable detector for possible weak points of the terminal and a valuable test field for mitigation actions to find the most efficient approach.
