  1. Cockpit Design Factors effecting the design of a complex task

  2. Learning Goals • Understand a practical example of a complex safety critical task • See how various methodologies might be applied to it • Give an account of some basic principles of design • Give an account of how different systems may require different design solutions for their cockpits • Discuss Crew/Cockpit Resource Management • Identify the relevance of occupational psychology

  3. Reading

  4. Cockpits • What is a cockpit • What is controlled • What feedback is needed - obvious egs • What feedback is needed - less obvious egs

  5. Other comments • admin paper work • Other systems • Dynamic factors

  6. How to control these systems • control columns various, side stick, wheel etc • pedals • levers • switches • Buttons • And…….

  7. Feedback • digital/alphanumeric • analogue displays • indicator lights • on/off • colour • flashing • intensity • auditory alarms

  8. So...... • complex - many different subsystems • many different controls • many different displays

  9. Design - what do you design • Artifacts i.e. things • or • Systems • design tends to viewed as a discrete activity. this is misleading as this leads to the notion of a design phase as preceding operations and decommissioning.

  10. Consequences of this view of design • people design things • neglect of systems aspects • training, procedures and organisational factors • devaluation of user as design aid

  11. An alternative view • design is a conduit for bring relevant expertise to a point application

  12. Back to cockpits • First step (idealized) • define system and system needs and therefore design goals • Undertake a task analysis • how • on whom • for whom

  13. Occupational psychology in these matters • the operator system interface • training • procedures • organisational factors

  14. Some issues that might arise • Operator system interface • Training • Procedures • Organisational Factors

  15. Automation • fewer crew members • less expertise • delayed, degrading systems knowledge • system opacity • system monitors • constrained by others lack of knowledge

  16. ‘Errors’ and how design could have prevented them • Kegworth • SAS MD91 • Take off weight on Air UK • Landing at Bucharest • Tenerife

  17. Summary • nature of task of flying an aircraft • complexity of task • notion of design as an ongoing process • notion of design as a conduit or path for expert knowledge • design is a superordinate construct • the applied psychologist is appropriate at many levels
