Absolutely true about Chinese offsets 737NG.
I am just wondering when the Airlines are starting to calculate the higer fuel burn...
I add 300 kg for the early descent alone, plus another 400kg
for those huge wide enroute R/Vs I cop from time to time for
"arrival separation" esp into PUD, and CAN from the North.
So there's 700kgs extra on top of CFP fuel before I even start
looking at anything else.
I only ask twice, the third time I informing them of my new heading until clear of weather (sometimes this triggers some very interesting exchanges on the frequency).
I do too. Check your TCAS next time the babbling starts -
and then watch where your following traffic starts going....
