AI Technical Summary
Technical Problem
Existing engine thrust control systems fail to effectively manage thrust when air data, particularly air temperature data, is unreliable, leading to inadequate engine control.
Method used
A method and system that utilize sensors to obtain thrust lever position and air data, detect compromised air temperature data, and adjust engine rotational speed based on thrust lever position and non-compromised altitude and Mach number data to control thrust, employing an alternate thrust control mode.
Benefits of technology
Enables reliable engine thrust control even with compromised air data, preventing engine operability issues like surge or stall, and allows for smoother transitions between thrust settings.

Abstract
Systems and methods for controlling thrust of an engine for an aircraft are described herein. A position of a thrust lever for controlling the engine is obtained from one or more sensors. Air data is obtained from one or more air data inputs. An air temperature data input is detected as compromised from the air data. In response to detecting the air temperature data input is compromised, a target engine rotational speed is determined based on the position of the thrust lever and at least one of altitude data and Mach number data from the air data. A rotational speed of the engine is adjusted to the target engine rotational speed to control thrust of the engine.
