FS, the straight-in approach is probaly the hardest to judge, but if you use an IAPt. well down the runway/field, if too high you can `s` turn to lose distance.One important point is that one should practice the descent aspect at each configuration change once trimmed at the correct speed, as it is all too easy to select gear/flaps etc, and then find that the` picture`, once stabilised now shows you will fall short.
For info at 25 deg bank, your turn radius varies , at 100 kts it is about 2000 ft, at 150 kts it is 4000 ft. in still air.
I agree with in IMC, increasing descent speed and then using that excess to position when VMC, even accepting a d/w landing....
