instrument approach

A landing approach made without visual reference to the ground by the use of aircraft instruments and ground-based electronic or communications systems or devices. An aircraft making such an approach should be flying in accordance with an IFR (instrument flight rules) flight plan. An approach carried out with the help of systems such as ILS (instrument landing system), MLS (microwave landing system), GCA (ground-controlled approach), VOR (very high frequency omnidirectional radio-range), TACAN (tactical air navigation), LOC (localizer), and GPS (global positioning system) would be categorized as an instrument approach. See ground-control approach.

I don't recall my exact reaction the first time I contemplated an instrument approach procedure via its plate, but it probably was something along the lines of, "You've got to be kidding me." How can any pilot be expected to fly to such exacting detail?
The report said the pilot was making an instrument approach to the Eugene Airport, meaning conditions required him to fly primarily by referencing navigation instruments rather than by sight.
