DUAL OPERATION HUMAN-MACHINE INTERFACE

The paper describes a Dual Operation concept and one example of its design. The amount of information the pilot must process, already high in c urrent Air Traffic Management (ATM) operation, will increase dramatically in the envisi oned future ATM environment. New pilot functions will require new levels of automation. Thus cockpit displays must be modified in order to facilitate s and to manage the increased information available. O ne approach to these challenges is to adaptively modify the displays depe nding on current pilot tasks and situation. Simply adding functionality to current day displays has the potential to reach an unacceptable level of complexity. However, completely new displays requi re tremendous development and certification efforts. Therefore one of the key challenges of HMI design is how to modify current display to provide pilots with adaptive task assistance. In ot her words, how to offer new adaptive HMI functionality without significant modification of al ready proven HMI designs. This paper describes an approach to utilize the unused space on the disp lay for showing context adaptive additional functionality without modification of the HMI manageme nt procedure with which pilots are familiar. Pilots can use the standard HMI management functions o r can use context-dependent offered by adaptive automation. This effectively cre ates two modes of operation - the Dual Operation system. This system offers a path towards th e transition to more adaptive automation support, better procedural control of the aircraft, and context dependant decision making.
