.......south bound leg of this A/C. He said they said there was a "black-out" during the leg, but all came right after a while
If such an event occured, no doubt there would have been several ACARS sent.
message from AF 447 regarding the aircraft being in "hard turbulence"
On the other thread I raised this issue also. I cannot recall in all my years of flying that I ever sent an advisory (HF) to our flight following re turbulence. It may have been a write up item, or comment to ATC. Someone replyied that it was an AF inflight proceedure, and normal.
