773-ER start-up with GE90-115BL1
Prompted by the "RB211 starting" thread.
BHX-DXB-CMB and return last week on 4x Emirates 773-ER with GE90-115BL1.
On each start-up there was a fearsome resonance throughout the cabin that stopped at the same time as an apparently engine related shriek also stopped. The way the shriek suddenly stopped, stuttered, and then finally stopped, rather than fade away implies something mechanical actuating, but I wonder what it was, please?

Thanks to further searching I found this, but it still doesn't explain the shriek cessation: boeing 777-300 startup sounds - X-Plane.Org Forum
