1. A method for synchrophasing aircraft engines, the method comprising:
receiving data indicative of a first sensed vibration level associated with a first aircraft engine and a second aircraft engine operating at a substantially same operating speed, the first sensed vibration level being higher than a target vibration level;
commanding one or more first momentary increases in operating speed of the second aircraft engine;
after the commanded one or more first momentary increases in operating speed of the second aircraft engine, receiving data indicative of a second sensed vibration level associated with the first aircraft engine and the second aircraft engine operating at substantially the same operating speed, the second sensed vibration level being higher than the target vibration level; and
commanding one or more second momentary increases in operating speed of the second aircraft engine.
