So far during my primary flight training, the approach slope indicator lights haven’t really been something I used or worried about. Landing my little Cessna on a 4,000+ foot strip in broad daylight has gotten easier and easier, and even when I was terrible I was more concerned about flying a stabilized approach than being “on” the glideslope. Sure a quick glance now and again to confirm that I wasn’t too low has been helpful, but it wasn’t among the tools I relied upon to bring me safely into the airport. And then I flew at night, and realized exactly how useful that little strip of lights can become.
