With the X1, the first purely electric aircraft study from Heart Aerospace took to the skies. The demonstrator of the Swedish-American company, founded in 2018, has a wingspan of just over 32 meters (approx. 105 ft), a length of 23 meters (approx. 75.5 ft) from nose to tail, and a takeoff weight of 11,340 kilograms (approx. 25,000 lbs). This makes it the largest battery-powered aircraft ever to fly.

The flight took place in calendar week 33 at Heart Aerospace's X1 flight test site at Plattsburgh International Airport. This is a regional commercial airport serving a community of 20,000 residents in northern New York State. The manned flight lasted 27 minutes, during which the X1 reached an altitude of 335 meters (approx. 1,100 ft) above ground, and its all-electric propulsion system delivered a power output of > 1 MW.

The flight was conducted under a "Special Airworthiness Certificate" from the FAA in the "Experimental" category (SAC-EC), with the test program covering taxiing, takeoff, climb, maneuvers, and landing. The aim was to demonstrate fully electric flight on a scale relevant to commercial operations.

E-Planes Would Currently Be More Economical Than Their Kerosene-Powered Counterparts

The fully battery-powered X1 consumed electricity worth approximately 5 US dollars during its maiden flight. The flight took place against the backdrop of a continued rise in global jet fuel prices, which averaged 3.50 US dollars per gallon in the week ending August 7—a 63 percent increase compared to the previous year. This highlights the potential of electric propulsion to achieve structurally lower operating costs for aircraft while freeing airlines from the fluctuations of global oil markets. "With the maiden flight of the X1, Heart Aerospace has demonstrated electric flight on the scale of a commercial aircraft," emphasized Anders Forslund, founder and CEO of Heart Aerospace, as he explained the significance of the flight: "Electric commercial aircraft have the potential to fundamentally change the economics of airlines and, ultimately, reduce the cost of air travel for passengers. This is at the core of our vision for widespread air transport, where electrification enables more affordable, frequent, and cleaner flights to and from airports near where people live."

The Role Model Is a Hybrid-Electric Production Aircraft

The concept study is based on Heart's production aircraft, the ES-30, and is intended to validate key technologies, aerodynamics, flight performance, and the company's organizational capabilities. The ES-30 is a hybrid-electric regional aircraft with 30 seats and fixed wings, designed for certification under FAA Part 25. It has already received purchase commitments from airlines such as United Airlines, Air Canada, and JSX.
