Plain English Meaning

A standard ILS approach where the pilot must be able to see the runway environment by 200 feet above the runway, with at least about half a mile of visibility. It is the most common ILS approach and has the highest weather minimums of the three ILS categories.

Full Definition

A precision instrument approach using an Instrument Landing System (ILS) that permits descent to a decision height (DH) no lower than 200 feet above the touchdown zone elevation, with a runway visual range (RVR) no less than 1,800 feet (with touchdown zone and centerline lighting, otherwise 2,400 feet) or a visibility no less than 1/2 . It is the least demanding of the three ILS categories in terms of equipment, qualification, and weather minimums.
