Autothrottle with one engine lost

[Bruchpilot69 0]

Is it a bug or why it is not possible to re-engage the AT after one engine is lost ?

When I simulate engine failure after start and disengage the AT for a while,

later its not possible to re-engage it again. :(

Both thrust levers are in the same, parallel postion....

PF may disconnect AT.

engine off : thrust lever to retard, then fuel lever start cutoff.

autothrottle should not be used with one engine inoperative ... seems you get your answer ....

 

all the best.

I got this before too and I thought, although it says you shouldn't use it, that it would still be possible to re-engage it. I saw the guy in this video re-engage it at a later point

depending certainly on the ops and SOP.

 

should not be used is not meaning you cant use but it s better not.

 

did you try in the same conditions as on the video?

Do not believe the autothrottle will engage with only one engine

[ajacied551 1]

The Autothrottlle system is not able to re-engage when there is a thrust differential of 2000 pounds or when there is a thrust lever split of more than 10 degrees between both engine's.

The video is recorded on the classic, this is the ng.

Regarding that video - don't hit the TOGA button like that. You push them up with your hand on top and then hit the TOGA button from there.
