1) pressing a vert mode with athr on makes it going to climb thrust. you can use toga thrust for 10min. but as soon as doing the clean up with a vert mode of ap, it will be climb N1. without fds, i would say that you have to order climb thrust. in my last company flying in africa, we didnt use athr for go around, we switched it completely off when flying manual. so there we ordered climb power in GA
2) depends on wind. single engine i prefer gdown f15 two nm before descend point( because of the power changes etc.). when i do a just for fun approach while lineflying, i fly it with flaps 5 to the descend point and at 2000agl the gear comes down. makes that approach more interessting. anyway, in training or sim check with TWO engines make it 2nm, looks goood and makes examiners happy.
