COCKPIT DISPLAY OF TRAFFIC INFORMATION (CDTI) ASSISTED VISUAL SEPARATION (CAVS): PILOT ACCEPTABILITY OF A SPACING TASK DURING A VISUAL APPROACH 1

At many busy airports maximum efficiency and minimum delay occur when visual approaches are being conducted by pilots using visual separation from traffic for a portion of the approach. Pilot willingness to accept responsibility for visual separation also affords controllers maximum flexibility in traffic management under conditions of high traffic load. It may be possible to extend that efficiency to lower weather conditions if pilots are able to perform the same separation tasks by reference to a Cockpit Display of Traffic Information (CDTI) in lieu of visual contact out-the-window (OTW). This concept has been developed under the name CDTI Enhanced Flight Rules (CEFR); however, this paper will use the more descriptive and current term of CDTI Assisted Visual Separation (CAVS). Use of CAVS procedures may be applicable during visual or instrument approaches. This paper will mainly discuss the visual approach application since it will be the likely initial implementation. It will also review the maturity of the concept, including pilot objective and subjective results from four simulations. These results indicate positive pilot feedback and good performance.
