The Future of Electric Aviation and Artificial Intelligence presents a unique collection of proceedings papers from two multi-disciplinary symposiums on sustainable aviation and unmanned systems, offering a comprehensive view of the latest research and insights. The International Symposium on Electric Aviation and Autonomous Systems (ISEAS 2023) presents aerospace, autonomous, and piloted unmanned systems research. The International Symposium on Unmanned Systems, AI, Design & Efficiency (ISUDEF 2023) gathers researchers, scientists, engineers, practitioners, policymakers, and students working on topics in the unmanned systems industry and artificial intelligence (AI).  The collected papers provide insights on a broad range of current issues in aviation, including hybrid, electric, all-electric, and fuel cell aerial vehicles, electric generation, energy storage, propulsion technology, design issues, AI applications, efficient operations, and new identification and detection systems that adapt to the latest technology standards. ISEAS 2023 and ISUDEF 2023 allow researchers, scientists, engineers, practitioners, policymakers, and students to exchange information and professionals to present new technologies and developments and discuss future direction, strategies, and priorities in aviation and sustainability.
