Navigation and approach systems play a significant role in the safe flight and landing of the aircraft. Instrument landing system (ILS), in the appropriate direction of the aircraft and the glide angle, horizontal and vertical guiding the aircraft, for automatically approach and landing runway is the most widely used in precision approach navigation system types. In this study, the parts, operational categories, working principle and importance of the ILS are mentioned.eninfo:eu-repo/semantics/openAccessInstrument landing systemOperation categoriesPrecision approachAlet iniş sistemiOperasyon kategorileriHassas yaklaşımArticle211821
