The invention deals with the restriction on the mode change of an engine due to latching in the case of restarting the engine that has stopped in flight. A FADEC that controls an engine of an aircraft in accordance with a mode, includes a latch operating section that latches the mode, and an in-parking/in-flight determining section that determines whether the aircraft is on the ground or flying off the ground. The latch operating section operates when the in-parking/in-flight determining section determines the aircraft is on the ground, and does not operate when the in-parking/in-flight determining section determines that the aircraft is in fight.

Provide is an anti-icing system that can cause anti-icing devices to properly operate even if a breakdown occurs in a switch after a pilot sets the switch. An anti-icing system of the present invention that controls operations of anti-icing devices provided in an aircraft includes: operation mode selecting means that selects an operation mode of the anti-icing devices; and control means that controls the operations of the anti-icing devices according to the operation mode selected by the operation mode selecting means. The operation mode includes at least a manual mode, an automatic mode, and a stop mode, and the control means controls the operations of the anti-icing devices in the automatic mode if detecting that a breakdown occurs in the operation mode selecting means when the manual mode or the stop mode is selected by the operation mode selecting means.

Anti-icing system and aircraft

To improve the reliability of a control in a control system for devices included in an aircraft, such as engines. An engine control systemfor controlling enginesof an aircraft includes a FADECincluding a calculation processing unitfor performing control calculation, and a first memoryfor storing abnormality detection information that indicates that the calculation processing unitdetects an abnormality occurred in a sensorand an actuatorused for a control. The abnormality detection information is not erased but still stored in the first memorysince the first memoryis not cleared even if the engineis stopped. As a result, referring to the abnormality detection information makes it possible to avoid using a device having a low reliability, in which an abnormality is detected, for the control.
