ABSTRACT:
A gas turbine engine with dual fuel controls is disclosed. The controls have individual sensors that monitor N2. Each control uses the average value of N2 from both sensors for providing fuel to the engine and performing other operations. The fuel controls contain signal processors capable of determining if their respective sensors are operating out of range, in which case the fuel control uses the value of N2 from sensor associated with the other fuel control. If both sensors are out of range, the signal processors use a stored value for N2 or a value synthesized from another engine parameter. The signal processors are also capable of retesting the sensor over successive cycles to see if the sensor has corrected and is within a tighter range. If the difference between sensor values exceeds a range, the sensor with the best value for N2 is used.
