if the airport is equipped with the right navaids, you can always use a VOR DME approach, or even an NDB if it suits you. However, you need the appropiate approach plates where distances and altitudes are displayed.

Non precision approaches (that's an approach without a glideslope signal) are just a thing that you need to practice many times before you master it. It's much about how you "feel" the aircraft, and how well you can anticipate speed/altitude changes and make the correct adjustments. But keep a steady eye on the VASI/PAPI lights at the side of the runway. I always have a bigger safe-margin when doing non-ILS approaches, since my "feel" will never match the accuracy of a GS signal

It's 4.30am so I'm going to bed, hopefully you'll get better replies than mine.

That's the best link I've seen this year.
