Supporters of functional interface design argue that direct interaction with the essential functional relationships of a system may aid in the acquisition of domain-specific skill. To evaluate the potential use of a functional display in assisting in the development of piloting skill, twenty novices were trained on either a conventional display or an alternative display that displays the functional relationship of power and airspeed (the Oz display). Novices trained on the functional display showed greater control of power and less deviation from a flight profile over multiple maneuvers. Implications for future research and potential uses in training are discussed.
