Questions about procedure/functionality (LEFT GEN OFF)

Hi,

Its bin a while since a tried to managed this aircraft and was doing some test flights around EKCH . I remember a previous flight in real life where the pilots after takeoff postioned the Engine Sync to N1.

I cant recall why but i also did this in the sim. 

During my descent i accidently switched the EngineSync button to N2 before setting it to off and i heard this "pling" as you hear when you couple the AC generator on (GPU like)

Frome the real life i dont recall the Engine had all the options that comes with this sim (regarding to engine SYNC options (N1,N2 etc)

Why did the move of Engine Sync to N2  trick the LEFT GEN to off ? and what is the purpose of this Engine Sync ?

Thanks

The engine sync is there because on some airplanes you can tell in the flight deck that the N1's are a couple of % off.  I feel badly for the person in Row 33.

The plane should EPR sync when they're in .03 of each other.  As engines get tired the same EPR does not bring the same N1.  Thus the need for N1 sync.

We don't use it until cruise.  Once again as engines get tired they both will make the rated climb EPR at different N1's.  Using the sync at that point will drop one of the engines performance to match the other's N1.
