Accelerating Sustainable Electric General Aviation with Fast-Charging Networks at Regional Airfields: Opportunities and Challenges

Electric aviation (eViation) is a promising pathway for sustainability in General Aviation (GA), particularly pilot training. However, challenges such as limited aircraft models, low battery endurance, long charging times, and inadequate charging infrastructure at most airfields—exacerbated by a lack of charging standardization—hinder eViation adoption. This study explores key factors influencing the feasibility of establishing a fast-charging network for electric airplanes in Switzerland, addressing infra-structural, technological, and policy barriers, as well as stakeholder concerns. Using a sequential mixed-methods approach, we analyzed 7000+ electric flight records and conducted an online stakeholder survey (n = 44) and 21 qualitative expert interviews. The findings reveal strong interest in eViation but highlight critical gaps, including sparse charging infrastructure and the need for standardization. Stakeholders emphasize transitioning to the Combined Charging System (CCS), integrating renewable energy, and implementing policy measures like subsidies and operational privileges. However, a chicken-and-egg dilemma persists: limited infrastructure hampers aircraft adoption, yet investment is difficult without widespread use. Lessons from the automotive EV transition highlight the need for strategic infrastructure expansion and coordinated policies. Remarkably, stakeholders prioritize network density over charging speed. This study identifies key barriers and opportunities for eViation adoption, providing actionable recommendations for the sustainable GA transition.
