VoltAero is developing a unique general aviation aircraft family, the Cassio, for safe, quiet, efficient and eco-friendly flight in electric and electric-hybrid modes. The company achieved a major milestone with the signing of an agreement to supply 15 Cassio 330 electric-hybrid aircraft with an option for an additional 15 to HM Aerospace, a prominent Malaysian flight academy. The aircraft will be used for pilot training once they receive EASA certification and approval from Malaysia's Civil Aviation Authorities.
