The study is focused on i) the investigation of task load reduction and task load re-allocation aspects and ii) the evaluation of the ratio between controller task load reduction and accuracy of MTCD/TCT tools.The modelled airspace contains 6 MUAC sectors and the 24h regulated CFMU traffic sample from 19 July 2005 was used as initial traffic. Results were compared with a baseline situation without use of conflict detection tools.
Fast time results showed an average task load reduction of 12% when MTCD only was used (that was consistent with FASTI previous results) and a task load reduction of about 21% when both MTCD and TCT were active. Task load was evenly distributed across the two controllers (~48% Planner and ~52% Tactical) when both MTCD and TCT were active, while task load distribution without use of conflict detection tools was less balanced (~36% Planner and ~64% Tactical).
With respect to accuracy of the tools, initial results showed that for 2% variance for TCT and 10% variance for MTCD, impact on task load seems small, contained around the ideal values. The results may feed subsequent real time simulations and may provide inputs to a business case study.
