This paper reviews the potential benefits of and the need for implementing a procedure for providing Visual-like Separation in Instrument Meteorological Conditions (IMC) through the use of a Cockpit display of traffic information (CDTI), for single runway arrivals and departures. This procedure is referred to as an “IMC CAVS” procedure in this paper. This paper reviews existing research and status of the current “VMC CAVS” procedure (a CDTI Assisted Visual Separation procedure authorized for use in visual meteorological conditions), discusses the potential for benefit in the NAS of an IMC CAVS procedure, highlights issues surrounding such extension of a CAVS procedure into IMC, shows results of an on-line pilot survey aimed at understanding these issues, provides a description of a CDTI capability aimed at addressing the primary issues, and analyzes results of real-time simulations of conducting such operations. Finally, the paper recommends next steps that should be taken in order to develop an operational IMC CAVS capability.
