Do you know where the carb heat is located?
There are no Carb Heaters in the 777. If you look above the NAV, Beacon, Logo & Wing light switches, there are three ANTI ICE switches with the positions of OFF/AUTO/ON, having these on AUTO or ON, they would normally work, but do not. Therefore, using the SHIFT+H combo is the only way to prevent the pitot tubes from freezing up, which causes (1) the speed indicator to drop, (2) the A/T to push the throttles fully forward, and (3) the actually speed to increase way beyond the VNE (Never Exceed speed).

The Anti Ice Switches in the red box, the NAV, Beacon, Logo and Wing light switches in the yellow box.

Do you know how to select TOGA?
Pressing CTRL+SHIFT+G. Or. Click on the circled area of the throttle quadrant in this image:

In the larger view, I have put red boxes around the TOGA Switches.
In the smaller view, I have placed an arrow on the area to click on and activate TOGA when you turn the view in the VC so you are looking at the throttle quadrant.
It's fairly easy to find if you have Cockpit Tooltips turned on

The autothrottle doesn't seem to actual control speed, and on take off it never went to climb mode. Is that function not working?
It works for me.

Are you programming the FMC? On the TAKEOFF page, are selecting the V1, VR & V2 speeds?

It seems like a pretty good product. I am used to flying other 767-300. I'm sure the plane will improve with time.
Update v1.2 will, hopefully, be released soon. That should improve it some more. ;)

Thanks for your help.
You're welcome. ;D
