• 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

3Imperial College

• 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

4Imperial College

MethodologyController-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.

5Imperial College

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
