What is the Continuous Descent Approach?
The United Parcel Service (UPS) is using ADS-B in trials at its hub in Louisville, Kentucky. The company is realizing savings while simultaneously reducing the adverse environmental impact of its flight operations. The traditional “step-down” landing approach requires planes to use high thrust to level off at different stages, resulting in more fuel burn and additional noise and pollution. ADS-B allows for an improved landing procedure called Continuous Descent Approach (CDA).
