Has this been rolled out to production planes now?
Ive tried a search on the forums, and couldnt find anything, but that could me as im not sure im using them right.
I ask cause I took a couple of flights with MON recently, both of which on G-ZBAA.
On the second one I realised we were taxiing and there appeared to be no engine noise till just before take off?
If its not rolled out it was the quietest taxi ive ever had.
