<P>PROBLEM TO BE SOLVED: To provide a control device for a gas turbine engine for aircraft can accurately make a misfire determination in a short time regardless of flight conditions and the operating state of the engine. Ž<P>SOLUTION: The control device for the gas turbine engine 1 for aircraft has a misfire determination block 3 for determining whether or not a combustor 2 is in the misfire state, and performs predetermined reignition operation when it is determined that the combustor 2 is in the misfire state. The misfire determination block 3 makes the determination based on whether or not the operating state indicated by two characteristic values of temperature and rotational frequency is within a preset misfire region. In particular, the characteristic value of the temperature is obtained by correcting change rate of gas temperature by engine inlet temperature, altitude and aircraft speed, and the characteristic value of the rotational frequency is obtained by correcting engine speed by engine inlet temperature.
