Reserve Requirements Push Electric Regional Aircraft Toward Hybrid Designs
Heart Aerospace has flown its X1 demonstrator, a 100-foot-wingspan electric aircraft it says is the largest yet to take flight, as it develops a 30- to 36-seat regional airliner. Co-founder and chief executive Anders Forslund argues that battery-only aircraft cannot economically meet reserve requirements for diversions, so Heart’s planned ES-30 pairs electric propulsion for short routes with a turboprop for range and contingencies. The company’s case is that this hybrid design can lower operating costs on regional routes where conventional jet engines are least efficient.
