Frequently asked questions

Flying electric

Electric aircraft have zero emissions and offer a comfortable, quiet flight experience.

Electric aircraft are more quiet, and there’s also less vibrations. Electric motors actively compensate for turbulence, giving you a smoother ride in all weather conditions. The carbon fiber composite fuselage is fully pressurised.

Our plane will have an operating range of 400 km (250 miles).

The state-of-the-art li-ion battery packs we are currently testing have a pack level gravimetric energy density of 250 Wh/kg. This gives an operating range of  400 km (250 miles), with our aerodynamically optimised design, relatively low cruise speeds, and a 25% battery mass fraction.

The environment

Aviation contributes to 2% CO2 of emissions, and with the exponential growth of air travel worldwide, the problem is about to get much worse. New rules are in the works to limit aviation emissions. Through CORSIA, the aviation industry is aiming for a carbon neutral growth from 2020. Meanwhile, the Swedish government has introduced an aviation tax to curb emissions, and Norwegian authorities is requiring all making all domestic flights to be fossil-fuel-free by 2040.

Our aircraft have zero operational emissions, and will be powered by clean energy. In addition, the carbon footprint of manufacturing and maintenance for our aircraft is several orders of magnitude lower than for other modes of transport.  The high utilisation rates of electric planes gives them a much smaller manufacturing footprint than electric cars.

Heart's airliner

The ES-19 aircraft will have 19 seats. 

The ES-19 will be certified for commecial operations by 2025.

Initially, our planes will offer point-to-point transportation between Scandinavian cities, before expanding operations to the rest of the world.

Certifying the aircraft is the hardest part about building a plane. Therefore, every design choice in our aicraft has been optimized for ease-of-certification.
