Well I wanted to do a bit of hand flying today while still in the climb mode. I have a key set up to dis-engage the autothrottle which I hit and got the warning and the message. I notice the auto-pilot was still tracking with LNAV/VNAV so all good so far. Before I got too far I thought I would make sure I could get the throttles back into auto mode so clicked the key again but and the message went away but the PFD did not display any speed mode at all. Hit th TOGA button and nothing. Turned off VNAV and back on and still no change. I mucked around for a while and in the end the way I got it back was to put the MCP into altitude hold and then back into VNAV mode.Surely there must be a key able to be set up to get it back into autothrottle mode. I can believe that it is the correct way to do it in a real 744.John Veldthuishttp://www.virtualpilots.org/signatures/vpa475.png

In my experience if I kill the autothrottle and then re-enable it while in VNAV mode, I simply have to hit VNAV again and it'll re-engage. Try that, it may have been getting confused when you hit TOGA.-stefan
