An electric aircraft is an aircraft powered by electricity . Electric aircraft are seen as a way to reduce the environmental effects of aviation , providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries . Most have electric motors driving propellers or turbines.

The two-seat aircraft is expected to be able to fly for up to 90 minutes, with 40% lower operating costs than piston power. The eDA40 has
864-543: A UAM system. NASA's concept of operations, or ConOps, relies on defined corridors for UAM craft which must then abide by specific protocols when inside the corridor. EASA's regulatory approach leaves local decision to “local actors” and will instead seek to certify the aircraft themselves for safety. They developed the VTOL special condition to certify the specific class of aircraft that were previously undefined. Aircraft need to be certified as airworthy, as well as registered with
960-810: A blend of the FAA Part 23, 27, 33, 35, and 36 requirements to certify its eVTOL. BETA applied for eVTOL certification under Part 23 with the FAA. BETA was the first manned eVTOL to receive military airworthiness from the Air Force. All VTOL and eVTOL aircraft that carry persons or property for hire must be flown by an appropriately certificated operator. Joby applied for a FAA Part 135 certificate to operate their own aircraft for UAM projects. Lilium partnered with Luxaviation to operate eVTOL jets in Europe. Pilots need to be certified to operate an eVTOL and remote eVTOLs. Pilots can obtain

1248-447: A detection and avoidance radar to navigate traffic, and software to track landing zones for repeatable vertical landings. Fly-by-wire systems translate a pilot's inputs into commands sent to an aircraft's motors, propeller governors, ailerons, elevators and other moving surfaces. They are essential in multirotor designs because human pilots cannot control multiple propellers without computer assistance. In June 2019, Honeywell introduced
1344-431: A fatal crash in early tests. One of the first vertical-takeoff-and-landing aircraft (VTOLs) was the 1924 Berliner No. 5.

In Ingolstadt , Germany the Urban Air Mobility project began in June 2018, involving Audi , Airbus ,
1536-431: A gasoline-powered Cessna and other aircraft in a series of trials verified by the Fédération Aéronautique Internationale . The Long ESA was found to be less expensive, have a higher maximum speed, and higher rate of climb, partly due to the ability of the aircraft to maintain performance at altitude as low air density does not impair engine performance. In 2017, Siemens used a modified Extra EA-300 acrobatic airplane,
1632-412: A gross weight of 193 kg (425 lb), giving a useful load of 108 kg (238 lb).

1824-428: A miniaturized computer specifically designed for UAM aircraft. Advanced autonomous eVTOL fleets require management software to scale to profitable levels. Pilot training is costly and expensive, and pilots themselves take up much of an aircraft's payload. So many manufacturers are designing aircraft that can fly autonomously as automation technology improves. Sikorsky is developing MATRIX technology, while Honeywell
1920-402: A more powerful motor. Even with the lifting capacity of an airship, the heavy accumulators needed to store the electricity severely limited the speed and range of such early airships. Fully electric airships are expected to be available again by the 2030s. In 1909, an electric free flight model was claimed to have been flown eight minutes, but this claim has been disputed by the builder of

Safety risks overlap with most current aircraft risks, including
3552-523: Is as a sustaining motor or even a self-launching motor for gliders . The most common system is the front electric sustainer , which is used in over 240 gliders. The short range is not a problem as the motor is used only briefly, either to launch or to avoid an outlanding (an unplanned landing while soaring). The first commercially available, non-certified production electric aircraft, the Alisport Silent Club self-launching glider , flew in 1997. It

In the concept phase, urban air mobility aircraft, having VTOL capabilities, are deployed to take off and land vertically in a relatively small area to avoid the need of a runway. The majority of designs are electric and use multiple rotors to minimize noise (due to rotational speed) while providing high system redundancy. Many of them have completed their first flight. The most common configurations of urban air mobility aircraft are multicopters (such as
4320-694: The FAA , a vertiport is an identifiable ground or elevated area, that can be associated with various equipment and facilities, used for the take off and landing of tiltrotor aircraft and rotorcraft. The industry has used different terms for describing the various levels of equipment and sizes of these facilities. Vertipads are simple landing pads designed to be used by one aircraft at a time. Vertiports or vertibases can feature one or more final approach and takeoff (FATO) and touch-down and lift-off (TLOF) areas, as well as several VTOL stands and other aircraft and passenger facilities.
