I fly in a consumer PC flight simulator. Among my virtual fleet is a fairly faithfully-reproduced MD-83.
One fairly strange detail I noticed is that enabling engine sync (either on N1 or N2) in the overhead, while on the ramp, triggers not just the alert on the annunciator panel, but also the master caution light -- why is this? Engine sync isn't a particularly abnormal condition. Is this just an inaccuracy in the simulator?
