In the past decades, interest in cleaner, alternative propulsion increased rapidly. Accordingly, novel approaches for aircraft propulsion are required to meet the spirit of the time. This paper aims to assess the viability of parallel hybrid-electric propulsion systems for General Aviation (GA) aircraft with state of the art technology. Therefore, a comparison to the conventionally powered competitors is performed by using initial sizing results. An assessment of clean sheet designs is performed, as well as an evaluation of retrofit designs. Additionally, parameter studies on battery specific energy and aerodynamic efficiency are conducted to analyze their potential in improving viability and advantages of such aircraft. The studies results indicate that parallel hybrid-electric light aircraft are able to offer considerable benefits over conventional aircraft, even with todays technological standards. However, several design aspects have to be taken into account to make full use of the benefits arising from these concepts.
