The preview and predictive information is introduced to cockpit display to make the future state of flight perceptible, so as to exert advanced control to vehicles. The multifunctional cockpit display with preview and predictor function is preliminarily designed by analyzing the landing process of an aircraft. An intelligent error signal display concept was proposed by applying optimal preview theory to flight height error display. The simulated design of 3D and 4D display were introduced. Finally, simulation experiments were given to compare the multifunctional display with the ordinary display.
