Hi,I sometimes does not get autothrust,V1 and rotate callouts even though i have engaged autoflight .Today i hit the PROF in 3000 feet and then all the sudden i get , v1,rotate and autoflight announcement in 3 seconds :-)The Autothrust did not engaged during takeoff btw.I remember that it was with default panel load state so it might be something here.ThanksMichael

I'm sorry if this is redundant for you, but its good to go over these points: Make sure apu off.Dial a flap selected matches fmc takeoff page.Spoilers armed.Autobrake RTO.Trim set.Go through all fmc pages, make sure there are no blank info spots.Press autoflight after engine start/during taxi to arm autothrottle.Also press PROF button during taxi.In the PMDG options menu, make sure you have "only in clamp mode" selected for throttle override and make sure your throttle is not spiking. When you push throttle past 70% n1, you should hear a click for the AT kicking in. When this happens, push your hardware throttle, if you have it, full forward. Oh, also, make sure you have green box in the eicas displayIf you still don't get the callouts, and the throttle doesn't clamp at takeoff power at knots, then I'm sure someone here can help. Screenshots help too

I was observing same issue when I set FLEX greater then 50. Try this - when same situation after departure appears again, quickly change FLEX temp below 50. If it helps, you will known where is the problem.From my point of view it's a bug.Michal Salek.

It must be a bug, same same today from cold and dark this time. When hitting autoflight on runway prior to acceleration PFD did go from ATS OFF to CLAMP 10000 but nothing even after spooling up to 70-75% , It will happen but only in about 2-3000 feet when i hit the PROF button.Procedures as usual with FMC fully operation programmed, spoilers armed etc.Michael Moe

I don't know if it helps but have you guys checked that the throttle doesn't spike or move. If it does the autothrottle will disconnect since it thinks that the thrust levers are manually overridden. At least I think but turning the "throttle move autothrottle disconnect" thing in PMDG menu to off fixed it for me.Manfred
