What Makes AirTOP Unique
Visualize the problem - and the solution - in 2D and 3D
Seeing a problem often makes it easier to identify solutions. To test different scenarios and measure impacts, AirTOP accurately simulates all user-defined airport and airspace operations, as well as rules, multi-agent tasks, and behaviors. A single graphical user interface provides easy scenario editing, as well as viewing of simulations in 2D and 3D. AirTOP features an easy-to-use integrated map-based application containing GIS capabilities, to allow a flexible background display of scanned maps, aeronautical charts or vector data, weather data, satellite images, and elevation data.
Customize data for better decision-making
AirTOP data is highly customizable and can be extracted and visualized using hundreds of built-in reports, or exported as spreadsheets or SQL databases for presentation to stakeholders. Create videos of simulations to portray the impacts of different scenarios to decision-makers. The project management tool allows users to define scenario variants while avoiding data duplication.
Purchase only the modules you need
AirTOP modules integrate with one another on a common platform to offer a scalable feature set. An airport project may begin with the Airside Aircraft module, and as operations grow in size or complexity, additional modules such as Airside Vehicle or TMA/TRACON can be added to extend the software’s capabilities.
Make better, more-informed decisions
Complicated decisions involving multiple moving parts require more than a simple spreadsheet. When considering making changes to airport or airspace operations or infrastructure, AirTOP assists with informed decision making. Accurately model any airport or airspace operation, and run fast-time simulations of complex scenarios to test options and examine all the ‘what-ifs.’
Get the most out of airport and airspace operations and capacity
At an airport, delays of minutes and the associated knock-on effects can translate into impacts on the bottom line. AirTOP’s broad spectrum of tools allows users to assess how scenarios impact various aspects of airport operations, and how decisions play out in terms of costs and efficiency.
