Hi
Mutt, at last you've gone unbalanced!!! I'm going to buy a lottery ticket, I have visions of my unbalanced friend,
J_T smirking!
I've seen some very good weight increases with B777 Increased Speeds, but none of the magnitude of 14,000 Kg come to mind. If it doesn't compromise your anonymity, which Airport and Runway is that?
On the topic of Packs Off Takeoff, do you use the APU to Packs option on the -300ER? Nice, but for minimal discomfort Vs Packs Off (which gives the same performance result), always thought it a lot of extra expense for a small gain.
Regards,
Old Smokey
