HI Guys1 I installed the version 1.1 on top of 1.0 and instead of improoving i had huge problems. The first one is that VNAv still dont work at all but the main problem is about the LNAV. I take off i engage autopilot I engage LNAV and VNAV With VNAV the plane climb like a rocket and the speed doesnt rise and LNAV doesnt follow the rute make a turn in a big angle making the plane fly upside down. On 5 flight all 5 the plane crashed after take off..Any idea? Thanks Alfredo

I had the same problem when I installed 1.1 over 1.0+VNAV patch, Today I reinstalled 1.0 fresh, then 1.1 and I'm getting better results. I'm flying a long distance flight now FAOR (FAJS with CS NAV DB) to KATL (Which is a Dela Flight) which is 7492nm (8400+ miles) and so far so good. My climbout to FL340 (FAOR elevation is 5000+ft) took 14 minutes, which is in line with climbouts I've seen on Flightaware, for a 200LR.  I tracked vertical speed which ranged from a high of 3800fpm on initial climb, to 1200-1400fpm closer to cruise. For an average of  a VS of 2071fpm. So if you installed 1.1 over the VNAV patch, try installing it over a fresh 1.0 install. The only issue I see now is calculated remaining fuel at destination. 91KLB now and climbing which I think is a bit much, with a max load (Fuel and Payload). It's a 16 hour flight (I'm testing endurance) and I'm only about 1 hour out, so I still got a long way to go.

Edit: Flight over - I'm getting the same rocking problem I got with the previous installation! Oh well, back to 1.0+VNAV patch, which has been very stable!!! Here's a full flight video I did with it. Note the problems on approach was caused by my video recording program (GameCam) not the 777.
