757 Go around and autothrust
 

If you disconnect the autothrust and then initiate a go around will the autothrust automatically rearm itself?

A/T remains armed , since flap extension or g/s capture and with the pushing of either go around switch , will give you go around thrust = 2000fpm.

to put a finer point on it, the a/t will kick back in only if the a/t was initially disconnected by pressing the toggle on either side of the thrust lever........if it is disconnected via the switch on the mode control panel then it will not activate upon pressing the G/a toggles............this is from the dim dark past so please excuse if the mists of time have scrambled the grey matter...hope it helps.

Thanks for the info.
