The machine is intelligent enough to realise the difference between a normal G/A and the windshear manoeuvre, not least because it's gone to great trouble to produce a great big 'WINDSHEAR' on your TV for you. Therefore it is only necessary to push the TOGA switch once. If you do it twice you are not going to fall out of the sky but it will make no difference to the thrust you get. I am guessing that Boeing consider the autothrottle application of max thrust as being aggressive enough to not need to write anything extra about it.
Seriously?
This is a tech log forum,not a forum to get some guesstimate advise from a PC sim player.
No grudge against you but come on,bit obvious here.no?
, so why don't we disengage the A/T once max thrust is set in auto flight?
Why would you if the automatics are doing their job properly?
