ABSTRACT:
This invention relates to a speed reference system for piloting an aircraft, delivering information on piloting in pitch, particularly during the phases of take-off and of go-round, wherein this system comprises a first voter receiving a first difference between a displayed speed and the real aerodynamic speed, a second difference between the real pitch attitude and a reference attitude and a third difference between the real vertical speed and a vertical speed limit; a second voter receiving the output signal of said first voter and said third difference and delivering the smaller of these two signals; and a third voter receiving the output signal of said second voter and a fourth difference between an aerodynamic speed limit and said real aerodynamic speed, and delivering the greater of these two signals.
