<p>PROBLEM TO BE SOLVED: To quickly and surely execute control communication by comparing the present speed value of a selected airplane with an input value and changing the default display of a control instruction. SOLUTION: A display processing part 303 compares the present values (present heading value, a present altitude value and a present speed value) of the airplane received from a radar or the like with control instruction values (an instruction heading value, an instruction altitude value and an instruction speed value) received from a dial input part 302. The information of CLIMB is sent to a display information preservation part 304 in the case that the control instruction value (in the case of altitude information) is higher than the present altitude value of the airplane and the information of DESCEND is sent to the display information preservation part 304 if it is smaller than the present altitude value of the airplane. When the information of automatically performing transmission is added to received information, the display processing part 303 transmits control instruction information to the display information preservation part 304 and a control instruction transmission part 307. The display information preservation part 304 performs display on a display 308, based on the transmitted information. In such a manner, the default display of the control instruction is changed.</p> |
