“…Concurrent technological advancements in EAA, such as enhanced battery efficiency, autonomous navigation, and vertical takeoff and landing (VTOL) capabilities, offer a promising avenue to address these demands sustainably [10]. The integration of EAA into cargo operations stands to significantly reduce air freight's carbon footprint, augment operational flexibility, and alleviate the pressure on overburdened ground transportation networks [6]. Electrified aircraft promise a notable reduction in CO 2 emissions, noise pollution, and energy consumption compared to conventional truck freight [11].…”

The relentless expansion of urban populations and the surge in e-commerce have increased the demand for rapid delivery services, leading to an increase in truck traffic that contributes to urban congestion, environmental pollution, and economic inefficiencies. The critical challenge this poses is not only in managing urban spaces efficiently but also in aligning with global sustainability goals. This study addresses the pressing need for innovative solutions to reduce reliance on truck transportation in congested urban areas without compromising the efficiency of freight delivery systems. This study contributes a novel approach that leverages electrified and autonomous aircraft (EAA) cargo shuttles to shift the bulk of air transportable freight from road to air, specifically targeting underutilized airports and establishing vertiports in remote locations. By applying data mining techniques to analyze freight flow data, this research identifies key commodity categories and metropolitan statistical areas (MSAs) where the implementation of EAA services could significantly mitigate truck-induced congestion. The findings reveal that targeting a select few commodities and MSAs can potentially decrease truck traffic, with electronics emerging as the dominant commodity category, and cities like Los Angeles and Chicago as prime candidates for initial EAA service deployment. Stakeholders in urban planning, transportation logistics, and environmental policy will find this study’s insights beneficial. This work lays a foundation for future innovations in sustainable urban mobility and logistics.

“…Voice radio transmissions should also be available for a project controller on the ground to relay through the aircraft, or on behalf of the aircraft. The recently developed propulsion efficiency index (PEX) guided the selection of a suitable aircraft category [44]. Aircraft meeting the above criteria had a range of at least 75 nautical miles, including power reserves for indirect routing, inefficient altitudes, loitering time prior to landing, and any adverse weather or headwinds that would decrease the range capability.…”

The successful deployment of Advanced Air Mobility (AAM) requires the safe integration of electric vertical takeoff and landing (eVTOL) aircraft in non-segregated airspace. However, a lack of practical deployment demonstrations can slow the regulatory progress. This study presents a practical deployment framework for the integration of eVTOL aircraft into public airspace, in accordance with the Federal Aviation Administration (FAA) special airworthiness criteria. This study focused on a corporate use case to provide a comprehensive scenario for enhancing intra-company mobility. The scenario supports early implementation and demonstration goals by removing reliance on air traffic management systems or air traffic controller separation services. The practical deployment framework included facility selection, route planning, terrain mapping, collision avoidance, aircraft selection, infrastructure requirements, vertiport placement, electric chargers, ground handling, operational staff, and cost estimates. Planners can use the framework as a template to inform the implementation of real-world AAM services using eVTOL aircraft.
