A LIMITED EVALUATION OF THE TRAFFIC ALERT/COLLISION AVOIDANCE SYSTEM FOR T-1A CELL FORMATION STATION KEEPING (HAVE CELL).

Abstract : This report presents the results of a limited evaluation of the suitability of the T-lA's Traffic Alert/Collision Avoidance System (TCAS) for cell formation station-keeping procedures during instrument meteorological conditions. The TCAS system was evaluated during cell formation takeoff, climb, cruise, and descent. The accuracy of the TCAS in bearing, range and altitude was evaluated. The aircraft were own through a high density traffic area to evaluate the effects of a high traffic density on TCAS performance characteristics during cell formation station-keeping. A safe cone of operation was defined. workload study was accomplished to evaluate pilot workload while using TCAS to fly cell formation in the T-lA.
