A control system for a turbine engine assembly includes a controller operable to control operation of the turbine engine assembly and to determine a trim configuration to balance a rotating engine structure associated with the turbine engine assembly. The controller is programmed to determine the trim configuration based on information indicative of an out of balance condition of the rotating engine structure and an assigning a quality score based on a determined veracity of the information.

System and method of performing fan trim balancing

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.

A system and method for detection of speed sensor position in an engine comprising speed sensors and a controller having channels each operatively connected to a different one of the speed sensors. A memory stores predetermined sensor position arrangements each identifying, for each one of the channels, a speed sensor connected to the channel, and predetermined engine parameter values each associated with a corresponding predetermined sensor position arrangement. A current engine parameter value is computed on the basis of received input data. The predetermined sensor position arrangements and the predetermined engine parameter values are retrieved from the memory and a predetermined engine parameter value that matches the current engine parameter value is determined. The predetermined sensor position arrangement associated with the predetermined engine parameter value is then identified and, for each one of the channels, the speed sensor currently connected to the channel is determined.

Methods and systems for detecting inclement weather in the vicinity of an aircraft engine are described. Vibration levels of the engine are monitored. Upon detection of an increase in the vibration levels beyond a threshold, an alert mode is triggered. At least one predetermined performance parameter is monitored while in the alert mode, and inclement weather is detected when the at least one predetermined performance parameter meets at least one inclement weather condition.
