occasional unfamiliar mechanical whining sound

[breadwild]

Brand new to this aircraft and will be curious about many things. Right off the bat, what is that occasional whining sound (like the flaps or gear moving) that lasts a few second? I was afraid I had brushed a switch or something. 

 

Thanks.

Brad,

 

What you're hearing is the hydraulic pump turning on as the pressure in the system drops from general hydraulic leakage.  You can observe this on the hydraulic gauges in the center pedestal.  Perfectly normal.

 

Enjoy the aircraft.

JGregory,

 

Thanks. No worries then.
