An FPM (30) and a target air attitude angle indication (32) are displayed on a PFD (10) which is an integrated instrument. The target air attitude angle indication (32) is an index showing a target angle of attack and a target air attitude angle, said target angle of attack being an angle of attack that is set as a target for the purpose of reaching a target flight path of an aircraft being piloted, and said target air attitude angle serving to show a target sideslip angle which is a sideslip angle that is set as a target. The PFD (10) displays the relative difference between the FPM (30) and the target air attitude angle indication (32), and the matching (overlapping) of the FPM (30) with the target air attitude angle indication (32) indicates that the aircraft being piloted is flying along a target travel direction. Due to the above, piloting with better path following performance than in the case of piloting based on a target ground attitude angle becomes possible.
