To paraphrase Henry Higgins, from My Fair Lady, "Why can't a nonprecision approach be more like an ILS?" A precision approach offers a three-dimensional chute down to the runway—as opposed to a minimum descent altitude (MDA) that lures pilots into descending as quickly as possible and then changing configuration to motor on to the missed approach point. But yes, Professor Higgins, there are nonprecision approaches out there that imitate, to a certain extent, the profile given on a typical ILS.
