The object of this thesis is to outline prospective assistance systems enabling a pilot to fly an airliner single-handedly. A cognitive modelling technique called Model Human Processor is introduced. Procedures and tasks involved in the operation of an aircraft are identified. Assumptions with respect to the single pilot design alternative are made. A simulation is implemented in Matlab in order to assess the pilots’ workload. Results allow for a procedure time and workload comparison of the two flight crew alternatives. The outcome of this analysis facilitates the design of potential additional pilot support systems that can reduce workload and improve situational awareness.
