There are quite a few tutorials out there, but, check out the following link - it's a low key clear run-down on BC localizer approaches.
http://stoenworks.com/Tutorials/ILS%20B ... aches.htmlAs well, the key to flying the BC approach is accuracy in terms of turns, airspeed and altitude. On the BC you don't have a glideslope to work with (such as with ILS), but if the airfield has VASI (Visual Approach Slope Indicator) lights [all red = too low, all white = too high, red & white = on a glidescope for the runway], you can use these in conjunction with your airspeed and altitude to visually "glide" down to the runway. Just note that there are quite a few types of VASI available (wikipedia them!).
Finally, practice practice practice - you'll find that eventually it will be quite easy to master!
