The Concept of the Instrument Landing System – ILS Continuity Risk Analysis Method

Abstract

This article is a continuation and extension of the Authors’ work on the ways to ensure safety of aerodrome’s traffic in the aspect of aeronautical data quality at the stage of its final operational use. The subject of the research is the ILS system, which is a critical element of airport CNS devices (communication, navigation and surveillance). Ensuring the quality and continuity of ILS is not only a legal requirement, but also an operational and business goal of the airport managing body. In the article the ILS system was characterized and special attention was paid to operational objectives, technical specifications as well as integrity and continuity of ILS service. The issues of reliability and availability of the operational ILS system were considered. A study of the objectives and the business continuity management standard were carried out. Then objectives and context were established and a study of methods for operational risk management in aerodrome’s traffic was conducted. Using the selected methods (including the Shewhart control chart), ILS continuity analysis was performed. Based on the results obtained, conclusions were formulated regarding the possibility of selected statistical methods’ practical application for management of the ILS system’s operational continuity.
