The design and flight test of a Continuous Descent Approach (CDA) procedure for regular nighttime operation at Louisville International Airport are described in this report. Results of the analyses of aircraft and FMS performance indicate that this procedure is operationally feasible and that aircraft may be vectored and spaced at intermediate altitudes where aircraft are outside the terminal area without compromising the separation between aircraft on final approach. Results of the analyses of economic and environmental benefits indicate that the CDA provides significant time, fuel burn, emissions and noise impact reductions.
