737 Go-Around Query
Flying stone: because your SOPs tell you to. I know, don't get met started.
GA is armed with GS capture OR below 2000 ft, so in this scenario it's armed.
The autothrottle will initially set thrust for 1000-2000 fpm climb, as normal with a climb GA. Can't remember the FD but IIRC same as with 'normal' GA: initially 15 degrees.
