1. A method for synchrophasing aircraft engines, the method comprising:
detecting, by one or more sensors, a sensed vibration level associated with a first aircraft engine and a second aircraft engine operating at a substantially same operating speed;
receiving, at a controller, data indicative of the sensed vibration level; and
commanding, by the controller, one or more momentary changes in operating speed of the second aircraft engine until the sensed vibration level substantially reaches a target vibration level, the momentary changes in operating speed of the second aircraft engine being commanded irrespective of phase information associated with imbalances of the first and second aircraft engines, wherein a magnitude of at least one of the one or more momentary changes in operating speed is related to a magnitude of a difference between the sensed vibration level and the target vibration level.
