All pilots worth anything should be able to judge a 3 degree glide slope with nothing at night just by looking at the angle to the runway out the window. Yes some runways have an upslope or downslope but you already know that if you did any homework.
True to a point. But, the FAA has gotten a lot more nervous about NPAs at night recently. There are now a lot of notes like the one for KBHM Runway 18.
