The paper describes a Dual Operation concept and one example of its design. The amount of information the pilot must process, already high in current Air Traffic Management (ATM) operation, will increase dramatically in the envisioned future ATM environment. New pilot functions will require new levels of automation. Thus cockpit displays must be modified in order to facilitate the pilot's future tasks and to manage the increased information available. One approach to these challenges is to adaptively modify the displays depending 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 require 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 other words, how to offer new adaptive HMI functionality without significant modification of already proven HMI designs. This paper describes an approach to utilize the unused space on the display for showing context adaptive additional functionality without modification of the HMI management procedure with which pilots are familiar. Pilots can use the standard HMI management functions or can use context-dependent "shortcuts" offered by adaptive automation. This effectively creates two modes of operation - the Dual Operation system. This system offers a path towards the transition to more adaptive automation support, better procedural control of the aircraft, and context dependant decision making.
