1. Imperial College 1 Towards a Controller Pilot Collaborative Decision Making Methodology A. Majumdar, W.Y. Ochieng, J.W. Polak Centre for Transport Studies Department of Civil and Environmental Engineering Imperial College

2. 2 En-route controller workload capacity constraint; Predicted traffic growth; Reduce workload (ATM 2000+): - automated tools; - re-distribute controller tasks; Progressive introduction of pilot aircraft separation tasks. Introduction - The Problem

3. Imperial College 3 Change in controller tasks: - other controllers/ pilots Pilots to do controller tasks: - conflicts - pilot workload? Pilot-controller interactions: - rules - collaborative decision-making? Task division: - what tasks? - when? Controller-pilot workload definition. The Opportunity

4. Imperial College 4 Methodology Controller-Pilots collaborative decision making Experience of real-time simulations What happens in other real-time, high risk fields? - electronic trading - battlefields - nuclear power stations Alternative decision making frameworks - decision trees, loss functions, pay-offs etc. - different objectives for different actors? Analysis of framework - alternatives need study.

5. Imperial College 5 1.How control tasks are defined and allocated to pilots and controllers? 2.How does interaction/ arbitration between pilots and controllers operate? Further issues: Fast-time modelling of decision making; Capacity definitions. Conclusions Feedback from controllers and pilots on a decision making framework to answer:
