Increased traffic congestion on urban road networks has impacted the travel time for commuters in highly populated urban centers. Urban Air Mobility (UAM) is recognized as a system that transports the passenger and air cargo from any location to any destination within a metropolitan area. UAM may offer a solution to the problematic issue of automobile urban surface transportation congestion. However, the predicted significant growth in the demand for integration of UAM operations into the existing airspace system in the next 20 years and beyond may exceed the capacity of current air traffic control (ATC) system resources, particularly the ATC workload. Many organizations in the aviation industry, academia, and government have conducted extensive studies on the issue of UAM airspace integration. Many of these proposed solutions involve high-level frameworks for managing UAM operations. In this paper, the combination of the Dynamic Delegated Corridors (DDCs) and full four-dimensional (4D) Required Navigation Performance (RNP) trajectories are proposed to enable UAM aircraft to integrate into the existing airspace system. Experiments will be conducted to measure and compare the ATC workload before and after the installation of DDCs and 4D RNP trajectories in the terminal control area (TCA) of an airport. The proposed approach in this paper is expected to help reduce the workload of ATC dramatically and contribute to the viability of UAM airspace integration into the existing airspace system to operate at low altitudes in the terminal controlled airspace together with other airspace users safely and efficiently.
