Hi
You guys are right but thease questions sound like CAA Eng licence q's and there all like this unfortunaltly. Type specifics cannot be brought into it, which makes the definitive answer hard to find! e.g the post that mentions the airbus pilot selecting idle, true, but this has no bearing on the question as an airbus has no auto throttle, its auto thrust. see what i mean about type questions getting messy! You have to think "CAA" autothrottle.
As for the 3B, iam a licenced avionic eng and were taught that 3B is no decision hight, thats the capability, what AWOPS says is not important for the question. Thats an operational concern.
Cheers,
Stu.
