摘要：The present invention refers to a method for controlling an aircraft propeller

system during thrust reversal, wherein it is checked whether each power plant is readyfor the transition to negative pitch, and where the propellers transition to negative pitchis controlled from a flight control system, such as only when both power plants are readyfor the transition to negative pitch, the flight control system instructs the aircraftpropeller system to reverse thrust. If a power plant failure is detected before a reversalorder is received, then the flight control system is informed of that failure condition, andthen the flight control system will disable the thrust reversal operation as long as thefailure condition remains. The method of the invention improves the aircraftcontrollability during landing operations, reduces pilot workload, and improvespassenger comfort during landing and taxing.
