'Go around, flaps 15!'
*TO/GA push
*Push thrust levers forward by strechting your arm.
*(Aim for 85% N1)
*Follow flight director. If you have a climb rate less than 1000fpm, increase thrust. If you have a climb rate exceeding 2000fpm, reduce thrust. Or leave it where it is if satisfies your goal. Eg. if you only need to climb 1000ft, you can also do with 800fpm ROC... But usually 85% N1 will give you a good rate.
