World's largest electric aircraft takes to the sky for the first time
American company Heart Aerospace has for the first time flown the X1 prototype — a demonstrator for the future 30-seat regional hybrid-electric aircraft, the ES-30. To date, it is the largest all-electric aircraft to have made a flight.
The test flight took place at Heart Aerospace's base at Plattsburgh International Airport in New York State and lasted 27 minutes. The aircraft climbed to approximately 335 meters, and its all-electric propulsion system developed over 1 MW of power.
During the tests, the X1 performed taxiing, takeoff, climb, maneuvering, and landing. The main goal was to verify the possibility of all-electric flight under conditions close to real operation. The aircraft ran exclusively on batteries and consumed approximately 5 dollars worth of electricity throughout its first flight.
Heart Aerospace believes that electric propulsion will eventually allow for significant reductions in operating costs and reduce airlines' dependence on fluctuations in aviation fuel prices. According to the company's estimates, the future ES-30 could have over 40% lower operating costs compared to previous generation regional aircraft. This should be achieved due to lower energy costs and reduced maintenance requirements for the electric propulsion system.
The X1 is a full-scale technology demonstrator created to verify the core technologies, aerodynamics, and flight characteristics of the future ES-30.
The production ES-30 is intended to be a 30-person regional passenger aircraft. It will feature a hybrid-electric propulsion system and has already attracted interest from major airlines, including United Airlines, Air Canada, and JSX, which have expressed their intent to purchase such aircraft.
The company is already building the first pre-production ES-30 at its manufacturing facility in Los Angeles. Flight tests for the aircraft are scheduled to begin in 2028, with commercial operation planned for 2031.
Heart Aerospace expects that with the development of battery technologies, the economic advantages of electric aircraft will increase. If the project is successful, the ES-30 could become one of the first commercial regional aircraft to widely use electric propulsion on short routes.
