Heart X1: the largest battery-powered electric aircraft takes flight
Heart X1, the largest battery-powered electric aircraft that flew, took a key step towards a regional hybrid transport supported by Air Canada.
An electric plane of more than 11 tons has just left the ground by its own means. Heart X1 flew its first flight on 12 August 2026 to Plattsburgh, New York.
Heart Aerospace presents it as the largest aircraft powered only by batteries that have ever flown. This stage is important, but the X1 remains an experimental aircraft: it will not transport passengers and does not yet represent the hybrid aircraft that the company hopes to commercialize.
Official announcement of the first flight
A real plane, not a flying model
The X1 has a wingspan of 32.3 metres, a length of approximately 23 metres and a take-off weight of more than 11,300 kilograms. Its high-hub wing carries four electric motors powered solely by batteries.
During its first exit, the piloted aircraft rolled, took off, climbed, manoeuvred and landed. The flight lasted 27 minutes and reached a maximum altitude of approximately 335 metres above ground level. The propulsion system provided more than one megawatt of power.
The mission was carried out under a special certificate of airworthiness issued by the Federal Aviation Administration in the experimental category. This permit allows flight tests; it does not constitute a certification for commercial passenger transport.
A flight that would have consumed five dollars of electricity
Heart states that the electricity used during this first flight cost about US$5. This spectacular sum must be interpreted with caution.
It represents only energy consumed during a relatively short test mission. It does not include the purchase of the aircraft, maintenance, crew, charging infrastructure, any replacement of batteries or airport charges.
The Next Web points out precisely that this amount does not correspond to the actual cost of operating an air service. It shows above all that electrical energy can cost much less than fuel used by a conventional regional aircraft.
No independent results detailing battery capacity, mass or ageing have yet been published.
The real goal is called ES-30
The X1 is used to validate the aerodynamics, electrical propulsion, systems and manufacturing methods required for the future ES-30.
Unlike the fully electric demonstrator, the ES-30 will be a 30 seater hybrid regional aircraft. The batteries will power its electric motors, while a fuel-based extension system can take over on longer journeys.
Heart announces a range of 200 km in fully electric mode and about 800 km in hybrid mode. The recharge would take approximately 30 minutes. These figures are manufacturer's objectives and have not yet been demonstrated with a serial device.
The first ES-30 pre-production device is under construction in Los Angeles. Its flight tests are scheduled for 2028, while type certification and entry into service are now targeted for 2031.
Why Canada is directly concerned
Air Canada announced an agreement in 2022 to acquire 30 ES-30s and an investment of US$5 million in Heart Aerospace.
Air Canada News Release on the ES-30
However, the timetable has changed. Air Canada was initially talking about an entry into service in 2028, whereas Heart is now 2031. Acquisition remains subject to the device's final development, performance and regulatory certification.
If the program succeeds, the ES-30 could be adapted to some relatively short Canadian regional links. Its true autonomy in cold weather, the availability of charging stations and Transport Canada requirements will need to be assessed.
Prices and availability
The X1 is a prototype and is not commercially available. Heart Aerospace did not disclose the purchase price of the future ES-30, and the value of Air Canada's contract was not made public.
The manufacturer states that the ES-30 could reduce direct operating costs by more than 40% compared to traditional regional aircraft. This projection depends in particular on the price of electricity, battery life, maintenance costs, certification and possible crew gains. It has not yet been confirmed in commercial operation.
Limits or Considerations
The first flight confirms that an electrical device of this size can take off and manoeuvre. It does not yet prove that it can carry 30 passengers on a regular route, respect the minimum energy reserves and operate several times a day in all weather conditions.
The EES-30 will be hybrid rather than entirely electric on journeys exceeding about 200 kilometers. It will therefore continue to consume fuel and produce emissions during these flights.
The certification planned for 2031 remains ambitious. Several years of battery testing, modifications and validation still separate the X1 from a commercial aircraft.
Conclusion
The Heart X1 flight represents a tangible advance for electric aviation: a life-size aircraft of more than 11 tons took off thanks to its batteries and four electric motors.
The next step will be much more difficult. Heart will have to transform this demonstration into a certified, reliable and economically viable aircraft. With 30 aircraft envisaged by Air Canada, the success or failure of the program could eventually be felt on Canadian regional services.
