Posky B777

[chris_ca]

Hi I'm having a problem with Posky B777 during climb, I always use this fuel calculator http://fuel.aerotexas.com/ to make sure i don't take off heavy with 12 tons cargo, for PAX figures i never touch those figures. So the problem is when i reach 20,000 feet the aircraft starts shaking left and right. My climb rate is 1800fpm with a speed of 330 knots but when i reach 35000 feet with a speed of 450 knots it stops shaking any help on this? thanks

Try 800 fpm above 20k and see how that works for you, Thats alot of airplane to try to drag strait up at 20k
