hey guys,first of all, i really enjoy this product, it's the best addon aircraft so far (i tried quite much). i am already using it since half a year and i m getting on with it pretty well, no problems so far.however, yesterday there occured a serious error... i cannot activate the autothrottle anymore, every time i click on the autothrottle button it jumps back to the downward position and autothrottle is not activated. is it possible that i misconfigured something in the fmc?i apologize in advance if the manual deals with this topic, but i did not find anything about it. thanks for your help! :)greets mario m.

>i apologize in advance if the manual deals with this topic, but i did not find anything about it. Sounds like the electric solenoid mechanism has failed... or it could be that you have no electric power to the solenoid?Check the manual on how to switch on the aircraft electrics... or use the forum advanced Search function to find information on the "autothrottle" not arming. Refine your search using PMDG and Subject only selections. I think it has been mentioned before.Hope this helps.Cheers.Ian R>

hey,first of all, thanks for your answer.however i searched for this topic by using the forumsearch and however i found a post which already dealt with this problem, it didn't help anything.yesterday i purchased 737 800/900 and there occurs the same mistake, i don't know why :( .i guess i do something wrong but i don't know why.before it went wrong, i clicked on something called "eng out" in the fmc, maybe the cause is situated there?please help me, flying without autothrottle sucks :((greetsmario
