Autopilot system is one of the essential equipments in modern aircrafts. The stable operation of autopilot system is an important part in flying safety. Human-computer interface is the communication channel between pilots and airplanes. For this reason, design of human-computer interaction interface under autopilot mode becomes very important. How to achieve a efficient, precise, reliable and comfortable interface is now a subject more and more researchers study. On the basis of introduction to autopilot system and interface in modern large aircraft, this paper offers some suggestions to improve existing interface and proposes a design based on large screen display and touch-control by analyzing the pilots' mental model.

From the functional design and emotional design of Information visualization, the consistency and experience design objectives of the visualization design of fighter cockpit integrated display are put forward. The specific strategies of achieving the two goals also are expounded. Pointed to the transform from the abstract, non-visual characteristics of the information into a visible, easy-to-understand interface, two methods of interface metaphor and ecological interface are discussed.
