That's what it was. When I brought the throttles up to 40% to "stabilize" the engines, then I hit TOGA and I left the throttles at the 40% setting. I will from now on use full throttles at T/O . Go to 40%, stabilize, than full pwr, then hit TOGA.

Yep, or even one tiny step better, first TOGA (in order not to overshoot N₁), then safely place hardware throttle to forward stop! In any way, I would assume resetting your hardware throttle to reflect the current sim state is a good idea in any way, as control spikes occur with various hardware devices. And don't forget you're in AT ARM probably more than once during a flight (think of reaching T/D...).

Roger that! Thanks.......I'm off to KMIA

(un)Check manual throttle override AT setting in your NGX setup,

Thank you Joost, that did the job!!!!

Just a little more info: Throttle hold removes power from the servos, as was said by Etienne. This is to prevent the A/T from doing anything dangerous if a malfunction occurs. RW- you push the throttles up to 40%, like Rick said, and then hit TOGA. The engines don't always spool up at the same speed from idle, so we push them to 40%, note that they are stabilized, and then hot TOGA. Probably not too important on a dry, wide runway. Throw in a narrow runway, some ice, and a crosswind, and you could be in the weeds.

Bit guessing here, but I believe besides AT malfunctions other reasons could be that it's easier for you to manually intervene. AFAIK you can always override AT, even with servos connected. But once the servos are taken off the levers, you practically can have manual control whenever you feel the need to (don't forget you're pretty much in the high speed regime when this happens, above 84 knots at least). This could be an RTO, but could also be maximum thrust if deemed necessary for some reason.

Hmmm. Let's think about that. The first item on an RTO is auto-throttle disconnect/thrust lever close.Windshear on departure can be completed with TOGA mode with the A/P and A/T on, or you can accomplish it manually with the A/T and A/P off. In either case, you're turning off A/T or you want it on.

I'm 64 and had no problem before. Don't worry I won't post again. Bye I was following the tutoral to the letter just like always. So don't tell me I didn't do it right. I just want to know how to uninstall and reinstall this great plane '

Are you looking for credit for having a senior moment or do you think it would make a difference if you said you were only 14? If you followed the tutorial you would not be looking at the LNAV or VNAV lights because you wouldn't care if they were on or off. Instead you would be looking at the FMA portion of the PFD (as described on page 0.00.58 of the tutorial). You would also might have noticed that the lights went out when you engaged TO/GA even before you installed the hotfix. So yes, I will tell you that you didn't do it right, regardless of what age you are. You can uninstall and re-install if you want to, but you will find that does not change this behaviour.

I loled at the Topic, and decided to check it out :(
