PURPOSE: To improve steering performance by providing an aircraft-shaped steering cue which moves vertically in accordance with required pitch change and rolls in accordance with a required bank angle in a device having a display surface to indicate a pitch, a roll attitude, etc., of an aircraft.

CONSTITUTION: A flight director display 28 comprises a fixed reference index 30, and an aircraft-shaped steering cue 38 capable of rolling, pitching, and translation related to the index 30. A control law device 14 is provided to generate a pitch attitude error signal 16 based on a command signal 10 from an inertial navigation device to supply a pitch attitude, a roll attitude, etc., and a navigation signal from a flight control device, and generate a roll attitude error signal 24 based on a command signal 20 from an inertial navigation device to supply a roll attitude, a selected nose direction, etc. Both error signals 16, 24 are coupled with each other by a control law device 18 to provide a synthetic steering cue signal 26 to control the display 28.
