<p>PURPOSE:To sharply reduce the load of monitoring work for the altitude of aircraft by executing the alutitude monitoring of aircraft based upon the minimum guide altitude. CONSTITUTION:The minimum guide altitude of an aircraft on a current position is compared with its current altitude to monitor the current alutitude on the current position (monitoring on current position), the minimum guide altitude on a forecasting position after the lapse of a fixed time is compared with a forecasted altitude (forecasting monitoring), and at the time of deciding that the altitude of the aircraft goes less than the minimum guide altitude, an alarm is generated. The alarm is informed to an air traffic controller by an alarm display on a data block indicating the air traffic controller on the screen of a control console display device 5 or the output of an alarm message to an auxiliary display device (printer device). Consequently, the load of an air traffic controller to the air traffic controlling work to an aircraft to be controlled flying by a instrument flight system can be reduced.</p> |
