All good stuff guys, keep the debate going.
As per the manual, Boeing recommends a/t out as well as A/p. I have always done that and call go around flaps 15 check thrust. The last two words always cover me.
It was only flying with some Americans that I saw this arm thing. As its not in the manual I questioned the rationale for doing it.
Denti be careful with these double clicks. If you have left the auto throttle in for Ga and then take out the a/t once the go around has been established sounds like a recipe for disaster. Completely non Boeing and truthfully would create organised confusion to the other guy!
