STBO

Surface Trajectory Based Operations (STBO) System Overview

The STBO system is a decision support tool that adds value to the external data processed by the Fuser. STBO provides common situational awareness to airport stakeholders by providing a common view of the airport configuration, runway utilization, and traffic management initiatives and flight data.

The STBO modeling engine detects flight state based on aircraft track data and flight data from external sources. The modeling engine uses the fused external data along with adaptation and user input to predict gate, spot, runway and fix usage per flight. It then predicts a 4D undelayed trajectory through these point.

This 4D trajectory is the starting point for the STBO scheduler which predicts when each arrival and departure will land and takeoff based on the current operating conditions at the airport and the other flights using the same runway. The scheduler uses these predictions to detect demand/capacity imbalances and assign gate holds to flights to manage the imbalance.

The STBO client displays flight data, flight positions, and airport information to airport stakeholders. It also provides view of airport demand and capacity in the form of timelines, tables and graphs. ATC users enter TMIs and airport configuration information into the client which improve the STBO predictions. ATC users also use the STBO client and predicted take off times to either manually or electronically negotiate release times into the overhead stream.
