Fast-Time Simulation (FTS) provides cost effective way to examine the impact of new aspects on operations and help stakeholders to make informed decisions. The simulation is executed at accelerated speed, which provides opportunity to test various scenarios. We record all relevant parameters that are customized for the operational environment (fuel burn, occupancy, duration and distance of the flight, duration and number of passengers served, etc.). The event logs are post-processed through tailored algorithms developed by the Fast-Time Simulation Experts. The results and conclusions are presented in the Final Report. Fast-Time Simulation can be used stand-alone or with Real-Time Simulation (RTS). In the latter case, the most promising scenarios can be selected for the RTS validation exercises.
