Herein provided are systems and methods for synchrophasing multi-engine aircraft. A phonic wheel (204) is coupled to a first propeller (130) of a first engine (110) of the aircraft. A sensor (212) is disposed and configured for producing a signal in response to passage of first and second position markers (420) on the phonic wheel (204). A control system (220) is communicatively coupled to the sensor (212) for obtaining the signal, and configured for: determining an expected delay between two subsequent signal pulses of the signal; identifying from within the plurality of signal pulses a particular pulse associated with the second position marker (420); determining, based on a particular time at which the particular pulse associated with the second position marker (420) was produced, that a rotational position of the first propeller (130) corresponds to a reference position at the particular time; and performing at least one synchrophasing operation for the aircraft based on the rotational position of the first propeller (130).
