Sigma Air Mobility, a Luxaviation Group company and global operator of aircraft and helicopters, is joining VoltAero’s efforts to introduce a family of hybrid-electric aircraft.

During the Farnborough Airshow, the French aircraft developer announced that Sigma will help to develop use cases and test the aircraft in various operational environments, with the goal of launching a route demonstration project at a still undetermined location.

VoltAero is developing a trio of aircraft with a parallel electric-hybrid powertrain. The lineup includes the five-seat Cassio 330, the six-seat Cassio 480, and a Cassio 600 model that could seat 10 to 12 passengers. It is starting with the Cassio 330 model and intends to begin flight-testing a full-scale technology demonstrator in 2025. The company hopes to achieve EASA type certification for the Cassio 330 in 202
