When an airport experiences low ceiling or visibility conditions the arrival capacity is significantly reduced. This is particularly true at airports that use both their main runway and their crosswind runway in Visual Meteorological Conditions VMC. The consequence of this is an increase in delays. A concept for continuing to conduct approaches in Instrument Meteorological Conditions IMC to converging runways has been proposed which calls for coordinating the approaches to the two runways such that a stagger between the aircraft is maintained. This procedure is known as Dependent Converging Instrument Approaches DCIA. This paper develops a DCIA procedure applicable to any runway geometry. The procedure is defined and modeled to capture its safety critical aspects. From this analysis recommendations are made concerning the stagger values and other factors relevant to applying this procedure safely....
