VoltAero selects Avidyne for customised avionics on Cassio 330 electric-hybrid aircraft
VoltAero yesterday confirmed its selection of Avidyne for the development of avionics to equip the Cassio 330, which includes customised software specifically tailored for electric-hybrid operations.
The Cassio 330 will be equipped with a glass cockpit incorporating Avidyne’s new-generation Quantum 14-inch displays in a dual primary flight display/multi-function display configuration. Quantum displays provide brightness and synthetic vision system at 4K resolution, as well as processor performance improvements over legacy systems.
Avidyne will customise the avionics’ human-machine interface specifically for the Cassio 330’s flight operations, facilitating the pilot workload while managing the aircraft’s electric-hybrid propulsion system. By accumulating and processing all aircraft information, the avionics suite will simplify the pilot’s decision-making process, as well as improve flight safety and pilot training.
“Our exclusive agreement with Avidyne ensures that Cassio’s avionics are just as advanced, innovative and capable for the future operators,” said Jean Botti, VoltAero’s CEO and Chief Technical Officer.
The Avidyne Corporation is a market leader in the design and manufacturing of integrated avionics systems for the aviation community. All its products are designed and manufactured in the US, with the company’s headquarters in Melbourne, Florida.
Avidyne President Dan Schwinn stated: “The Quantum open avionics platform has been specifically developed to meet the unique requirements of the next generation of hybrid aircraft, and is well aligned to support Cassio 300’s advanced hybrid electric systems and aircraft missions.”
The Cassio 330 is the first of three Cassio aircraft versions to be developed by VoltAero for seating capacities of up to 12 persons. VoltAero unveiled its first Cassio 330 prototype at last week’s Paris Air Show, where Avydine’s Quantum avionics suite was shown for the first time, incorporated in VoltAero’s full-scale Cassio 330 cabin mockup on its exhibit stand.
Designed with a five-seat cabin, the Cassio 330 will be powered by a 330-kilowatt electric-hybrid propulsion system. The follow-on six-seat Cassio 480 will have propulsion of 480 kilowatts, while the Cassio 600 is sized at a 12-seat capacity with electric-hybrid propulsion power of 600 kilowatts.
VoltAero uses electric motors in the aft fuselage-mounted hybrid propulsion unit for all-electric power during taxi, takeoff, primary flight if the distance travelled is less than 150 km, and landing. The hybrid internal combustion engine comes into play as a range extender, recharging the batteries while in flight.
Additionally, this hybrid element serves as a backup in the event of a problem with the electric propulsion, ensuring true fail-safe functionality. In addition, it has the capability to use sustainable fuels, including biofuel and hydrogen. VoltAero will assemble the Cassio aircraft in a purpose-built facility at the Rochefort Charente-Maritime Airport in France’s Nouvelle-Aquitaine region.
