PURPOSE: To reduce a load for an indicator by arranging an eyes direction detection sensor detecting the direction of the eyes of a pilot, displaying detailed information in an indicator on the eyes according to the detected result, and displaying less visible information in an indicator in the position other than the eyes direction.
CONSTITUTION: An eyes detection sensor 4 such as an eye mark recorder is arranged so as to detect the direction of the eyes when a pilot 5 watches indicators 1, and this information is inputted to a display processing unit 2. By means of the display processing unit 2, respective indicators 1 are controlled, so that a display format for the indicator 1 close to the line of sight is used for displaying a large quantity of information for detailed information, while a display format for the indicator 1 far from the line of sight is used for displaying approximate information limited only just within visibility of the pilot 5 for minimum information. For example, when the pilot 5 watches a right side indicator 1R, formats for a central indicator 1C and a left side indicator 1L are controlled so as to be simplified.
