The sequence and action diagram of both the pilots and the ATCO in the solution scenario. The ATCO withholds the take-off clearance when the prediction tool indicates a go-around. As a result, the runway is blocked for the arrival aircraft, forcing the ATCO to command a go-around for the arrival aircraft.

This paper presents a method to assess a novel procedure for Air Traffic Controllers, enabled by predictions of a machine learning-based go-around prediction model, regarding the operational risk of separation infringements and traffic alarms. In a previous work, potentially novel procedures were elaborated in human-in-the-loop simulations with Air...

Context 1
... aircraft are given a set of commands during a scenario, modeling the interaction of the flight crews and the ATCO. All commands and their activation order are predefined in the simulation environment and defined in the sequence diagrams in Figure 3 and Figure 4. Variables that influence the separation of aircraft are defined as parameters of the SuS. ...
Context 2
... solution scenario assumes that an algorithm, as presented in [6], predicts a go-around when the arrival aircraft is 4NM from the runway threshold. The sequence diagram in Figure 4 illustrates the procedure used by the ATCOs to handle the go-around described [11]. After observing the prediction at 4í µí± í µí± from the runway threshold, the ATCO does not provide a take-off clearance to the departure aircraft, given the potential conflict of the departure and missed-approach procedure. ...
Context 3
... departure aircraft is initilized at the starting position of the runway. The sequence of the scenario evolution and the procedures to resolve the simulated situation for both scenarios follow the sequence diagrams in Figure 3 and Figure 4. The sequence of interactions between the ATCO and pilots were implemented using the Simulink ® Stateflow ® environment. ...
Context 4
... indicates that the procedure enabled by go-around predictions could provide an additional barrier in the MAC-FAP AIM, preventing a conflict between missed approach and departure aircraft. However, the SuS approach assumes that work is done as imagined and defined in the sequence diagrams in Figure 3 and Figure 4. The results only hold if the procedures are applied within the defined limits of uncertainty over the SuS parameters. ...
