The aircraft of the future will be simpler to operate and more capable than today’s single-piston-engine aircraft due to a rare convergence of technologies, mainly Electric Propulsion and Information Technology. The transformation is already shaping the automotive industry with most of the legacy car manufacturers and some outsiders as well jumping into the electric car mass production bandwagon, all of them hoping to carve out bigger slices of the market. This paper describes some of the challenges and opportunities that arise when the upcoming technology convergence wave finds applications in a four/five- seat general aviation aircraft to enter in service by 2025.

General Aviation, which supports $200+ billion in total economic output, includes all aviation, other than military and scheduled commercial airlines, with half-a-million aircraft flying worldwide, ranging from two- seat training aircraft to intercontinental business jets and utility helicopters8. There are over 210,000 aircraft based in the US, another 135,000 in Europe and the remaining are spread all over the world, flying 25 million hours a year across 10,000 airports.
Among the many segments general aviation can be divided into, the piston-engine, propeller-driven airplane market is the one of interest for this paper. With US$ 718 million in sales in 2017, OEMs shipped 1,085 units out of which 936 were single-engine, and 149 were multi-engine aircraft. North America remains the largest
