Heart Aerospace Completes First Flight of X1, the Largest Battery-Electric Aircraft to Date

Heart Aero­space has com­plet­ed the first flight of its X1 demon­stra­tor, which the com­pa­ny says is the largest bat­tery-elec­tric air­craft ever flown. The mile­stone marks a step toward apply­ing ful­ly elec­tric propul­sion at a scale rel­e­vant to region­al com­mer­cial avi­a­tion.

The flight took place on August 12 at Heart’s test facil­i­ty at Platts­burgh Inter­na­tion­al Air­port in New York. The pilot­ed flight last­ed 27 min­utes, reach­ing 1,100 feet above ground lev­el. Dur­ing the mis­sion, X1’s all-elec­tric propul­sion sys­tem deliv­ered more than one megawatt of pow­er.

The air­craft, which spans 106 feet and weighs more than 25,000 pounds at take­off, oper­at­ed under an FAA Spe­cial Air­wor­thi­ness Cer­tifi­cate in the Exper­i­men­tal Cat­e­go­ry. The test includ­ed taxi­ing, take­off, climb, manoeu­vring and land­ing, with the objec­tive of demon­strat­ing elec­tric flight using a full-scale air­craft con­fig­u­ra­tion.

Heart said X1 con­sumed approx­i­mate­ly $5 worth of elec­tric­i­ty dur­ing the flight. The com­pa­ny cit­ed this as an ear­ly indi­ca­tion of the poten­tial ener­gy-cost dif­fer­ence between elec­tric propul­sion and con­ven­tion­al air­craft, although the eco­nom­ics of com­mer­cial elec­tric avi­a­tion will ulti­mate­ly depend on fac­tors includ­ing bat­tery per­for­mance, air­craft util­i­sa­tion and charg­ing infra­struc­ture.

X1 is a full-scale demon­stra­tor for Heart’s planned ES-30, a 30-seat hybrid-elec­tric region­al air­craft being devel­oped for FAA Part 25 cer­ti­fi­ca­tion. The ES-30 is tar­get­ed to enter ser­vice in 2031 and has attract­ed com­mit­ments from air­lines includ­ing Unit­ed Air­lines, Air Cana­da and JSX.

Heart says the pro­duc­tion air­craft is expect­ed to deliv­er oper­at­ing costs more than 40% below those of lega­cy region­al air­craft, pri­mar­i­ly through low­er ener­gy and main­te­nance costs. The com­pa­ny is cur­rent­ly devel­op­ing the first pre-pro­duc­tion ES-30 at a pilot man­u­fac­tur­ing facil­i­ty in Los Ange­les, with flight test­ing planned for 2028.

The X1 pro­gramme is intend­ed to val­i­date tech­nolo­gies, aero­dy­nam­ics and flight per­for­mance before they are car­ried into the ES-30 pro­gramme. Its first flight also gives Heart an oppor­tu­ni­ty to gath­er oper­a­tional data from a full-scale elec­tric air­craft ahead of the more demand­ing cer­ti­fi­ca­tion and pro­duc­tion phas­es.
