Airbus, Are you freaking kidding me?
What you forget Micro is that Airbus have had their 320 out for what... 27 years and they STILL haven't got their Performance act together. In my tenure on the frogmobile they've had 4 (yes FOUR) major Performance calculation changes, and certainly don't believe for a minute this will be the last change....
airbus meanwhile vehemently continues to blame pilots for everything.
Truer words never spoken. Have a double FAC failure and see how that bloody Toulouse crowd respond...
