Method and system for controlling thrust of an engine

A system for controlling thrust of an engine for an aircraft, the system comprising:

• at least one processing unit;
• and
• a non-transitory computer-readable memory having stored thereon program instructions executable by the at least one processing unit for:
• obtaining a position of a thrust lever for controlling the engine from one or more sensors;
• obtaining air data from one or more air data inputs;
• detecting from the air data if an air temperature data input is compromised;
• in response to detecting that the air temperature data input is compromised, determining a target engine rotational speed based on the position of the thrust lever and at least one of altitude data and Mach number data obtained from the air data;
• and
• adjusting a rotational speed of the engine to the target engine rotational speed to control thrust of the engine.

A computer readable medium having stored thereon program code executable by a processor for controlling thrust of an engine for an aircraft, the program code comprising instructions for:

• obtaining a position of a thrust lever for controlling the engine from one or more sensors;
• obtaining air data from one or more air data inputs;
• detecting from the air data if an air temperature data input is compromised;
• in response to detecting that the air temperature data input is compromised, determining a target engine rotational speed based on the position of the thrust lever and at least one of altitude data and Mach number data obtained from the air data;
• and
• adjusting a rotational speed of the engine to the target engine rotational speed to control thrust of the engine.
