In this online engineering PDH course, an overview of the current state and potential future development of aviation electrification is provided. Early stages of aircraft electrification are already underway. Small-scale electric and hybrid aircraft are under development, with small e-aircraft already certified to fly and with test flights underway for retrofits of existing aircraft. Electric aircraft are expected to increase operational efficiency and reduce emissions and noise. Because of the limited battery capacity of current technology, regional markets, which are defined as markets in which trips are less than 500 km (~310 miles), are expected to lead growth for electric hybrid planes. To illustrate the emerging current and future challenges of e-aircraft, a case study is considered of the potential use of small electric aircraft for short flights between small regional airports and a hub airport. This course is intended for mechanical, airport, transportation, and electrical engineers concerned with aircraft and airport design. This course is based on the National Renewable Energy Laboratory Technical Report, “Electrification of Aircraft: Challenges, Barriers, and Potential Impacts,” NREL/TP-6A20-80220, by Amy Schwab, Anna Thomas, Jesse Bennett, Emma Robertson, and Scott Cary, October 2021.
