I just want to emphasize what #chatta290 said above: “Be at 3000ft or so and semi-lined up with the cone you see on the map for the desired runway, then use the localizer and glide scope to follow it. Make sure you have landing aids on as well to help you…”
I fly the Cessna Citation X, which doesn’t have APPR, and use the exact same technique he suggests. I am able to nail the landing every time. Use the HDG and VS controls to stay on the localizer and glide slope. Have Landing Aid turned on in Settings so that IF will display the red landing cone starting at about 3nm out. When I cross the threshold, I reduce VS to about -400 for a soft landing, but this may vary with different planes. Of course, use the rudder at touchdown to correct for any windy condition. Others will have different landing techniques that work well for them, but this works well for me.
Hope this helps.
