Fast-Time Simulation

Terminal-to-Terminal Fast-Time Modeling and Simulation

AirTOP® airport and airspace simulation software is a comprehensive suite of tools designed to model, simulate, and visualize airport and air traffic operations in fast-time. This enables organizations to study the implications of infrastructural or operational changes before investing in costly and time-consuming construction projects or altering procedures.

Use AirTOP to measure and improve terminal, airside or airspace capacity, pinpoint delays, determine the impact of revised flight schedules, simulate new operational procedures, assess air traffic controller workload, and more. Choose to assess individual aspects of airport and airspace operations or run complete gate-to-gate, or terminal-to-terminal analyses. The software runs hours of procedures in mere minutes, so you can quickly assess outcomes of different scenarios and confidently make decisions that translate into safe, efficient, and cost-effective operations.

AirTOP is a modular solution, offering the flexibility to purchase the modules you need with the option to add modules over time. Take a look at the airport and airspace modules below and see what suits your needs best.

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 infomed 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.

What’s New in AirTOP

New features, fixes, and other improvements built specifically with your feedback.

Get all the benefits of the latest release by upgrading your software.

Upgrade Now

This latest version is launched as AirTOP 2024 as Transoft Solutions is adopting a new annual product versioning system. This new approach makes it easier to understand which version you are running to help ensure that you stay up to date with the latest features, improvements, and security patches.

Key features in this new release are:

New features

  • Terminal | A new wizard makes it quicker and easier to set up terminal models. 
  • Terminal | ICAO size codes and IATA Level of Service (LoS) are now available by default on each project to help users save time. 
  • Airside Aircraft | The new Decision Reporter adapter shows which rules were applied to any given aircraft, making it easier to understand the impact of an operational rule. It also shows which rules were not applied, allowing users to identify possible mistakes in the rule conditions. 
  • Runway Capacity Analyzer | It’s now possible to generate default Aircraft Type Approach Profiles without having predefined traffic in the project, benefiting analyses that use generated traffic mixes. 
  • TMA/TRACON | A new feature provides more flexibility to pause a simulation based on Runway Arrival Sequence events, and debug your model. 

Improved features

  • TMA/TRACON | You can now use vectoring areas to adjust the descent profile for a steep approach, preventing aircraft from descending faster than the Aircraft Type performance limitations.
  • All Modules | It’s no longer necessary to apply randomization manually as it will be automatically assigned when running multiple simulations in sequence.

Licensing Options

Transoft offers a range of licensing options to help small, sole proprietorships right on up to the largest multinational organizations meet their transportation design and analysis needs.

Network License

A Network license allows everyone within an office location to access the software from the company server with one person concurrently using at a time. Network licenses are not tied to a particular workstation or user. Multiple Network license seats can be purchased, and a license server keeps track of how many licenses are in use at one time. When Transoft’s software on a Network license starts, it first checks to see if a Network license is available to use. If so, a license is then checked out from the pool of licenses. When a user exits the application, the license gets checked back into the pool making it available to other users.
