If you are at your approach speed and fully configured the only way you will get "speed. speed. speed" (mel 34 or any other turn onto final)is if you pull into the turn. If you are at a 2-3 degree path it will not happen.
160 kts selected if you are going to turn into a head wind and you don't want thrust to increase to obtain gs mini. Even better have app speed magenta but the aircraft flying at approx 160 kts and as you turn finals your app speed will come up to what you are flying at (160kts).
to set up the app in the box a line from sheed to a 3 mile final will give you approx 6nm to run therefore 6*3 =18 =1800ft + 400ft elev = 2200 ft.
Sheed at 2500ft = profile + 300 ft therfore peg 1000 ft min till 1500 ft and it will work out nicely as long as you are below 200 kts at sheed (less experienced = lower speed at sheed)
