Hi. On my takeoff roll I spool the engines up to 55% when stable I press my TOGO (ctl+g) button on my yoke and the auto throttle used to activate and the green light would come on.

But for some reason it refuses to activate now, even if I push the keyboard buttons or try to mouse the button on the MCP. I have to push the throttles full forward to get to TO power then manually control the throttles to avoid going overspeed, while repeatedly pressing the Autopilot button before the AT will engage.

Any advice?

What green light? You need to arm the A/T first.

The A/T is armed by default it has 2 switches near to the top of the MCP below that a bit lower down is a button above a light marked AT. When toga is armed that AT light below the button turns green to show that the A/T has changed from armed to active.

This is not happening for me, but it has only just started to happen, and I haven't changed anything.

Peebee.

Ah gotcha.

 

Are your FMAs changing when you press the TOGA button?

No nothing at all happens, yet my TOGA button on the yoke is set up correctly. Also it works ok with the NGX and AXE. Using the same control profile for my yoke in CHManager.

Did you on the F/D ?

Have you set the key command in the 777 KEY COMMANDS menu?

Put everything as default. Go to fsx settings control engines and engine toga 

Yes F/D is on. If you read my post this has worked in the past with the identical set up so you can assume the key settings are correct in FSX especially as the NGX and AXE both work ok. I'm thinking there's something I have missed on the T7 panel. The only thing during my last 2 flights when this has happened I have spooled the engines up to 70%+ before engaging toga, normally I spool up to 55% then engage toga.

Has this made the difference?

You can't assume the key settings are correct, you need to check in the 777 FMC menu that the key bindings match.

Get your point.

The only thing is it worked previously and I haven't changed anything.

I'll double check.

Thanks Phil
