Piloting Assistance Method For An Aircraft, Making It Possible To Ensure The Availability Of An Automatic Pilot

A piloting assistance method for an aircraft, making it possible to ensure the availability of at least an automatic pilot, comprising:

• a first measuring step, implemented by a first measuring module, including measuring a vertical manoeuvre of the aircraft;
• a first computational step, implemented by a first computational module, including computing a first load factor from the measured vertical manoeuvre and from a setpoint vertical manoeuvre;
• a second measuring step, implemented by a second measuring module, including measuring an inclination angle, a pitch rate and a pitch acceleration of the aircraft;
• a protection step, implemented by a protection module, including:
• a computational substep), implemented by a computational submodule, including computing a second load factor from the measured inclination angle, from the measured pitch rate and from the measured pitch acceleration,
• a comparison substep, implemented by a comparison submodule, including comparing the first load factor with the second load factor in order to determine an applicable load factor equal to the load factor having the smallest value between the first load factor and the second load factor;
• a second computational step, implemented by a second computational module, including computing elevator control from the applicable load factor;
• a first sending step (E6), implemented by a first sending module, including sending the elevator control computed in the second computational step (E5) to the automatic pilot.
