A fundamental new theory for the operation of the instrument landing system (ILS) glidepath is presented. Simple new image array designs for use on severe sites are developed from this theory. The design makes use of Schelkunoff's simple circle diagram technique and it allows the separate specification of the radiated fields and the ground requirement. Two new glidepath arrays are particularly recommended from the many possible designs. The new arrays have been thoroughly tested at model scale and on a particularly severe site at Sydney airport. The approach also leads to a simpler setting up procedure which substantially improves performance.
