Alpha Electro - (prototype name WATTsUP)

Alpha Electro (prototype name was WATTsUP), the new 2-seat electric trainer: the greenest way of learning to fly!

Performance of the Alpha Electro 2-seat electric trainer is tailored to the needs of flight schools. Short take-off distance, powerful 1000+ fpm climb, and endurance of one hour plus reserve. The Alpha Electro is optimized for traffic-pattern operations, where 13% of energy is recuperated on every approach, increasing endurance and at the same time enabling short-field landings.

Ivo Boscarol, CEO of Pipistrel says: "With the ever growing cost of fuel it is time to rethink pilot training. Our solution is the first practical all-electric trainer! Technologies developed specially for this aircraft cut the cost of ab-initio pilot training by as much as 70%, making flying more affordable than ever before. Being able to conduct training on smaller airfields closer to towns with zero C02 emissions and minimum noise is also a game changer! Alpha Electro meets microlight and ASTM LSA criteria, as well as standards for electric propulsion.
Alpha Electro is our 5th electric aircraft project and the second to result as a commercial product."

History and development of the product:
The prototype WATTsUP was developed in partnership with Siemens AG, who provided the electric main propulsion components, and represents the next generation of Pipistrel's electric aircraft. Every single element of aircraft was refined to be lighter, more efficient and more reliable. The first 85 kW electric motor only weighed 14kg and was more powerful than the popular Rotax 912 series, typically used on microlights and LSAs. The 17 kWh battery pack was dual-redundant and designed to be either quickly replaceable within minutes or charged in less than one hour, thanks to the next generation of Pipistrel's Battery Management technology.

Frank Anton, Executive Vice President Traction Drives and the initiator of electric aircraft development at Large Drives, Siemens AG, said: “Siemens is developing electric drive systems with highest power-to-weight ratio for aircraft propulsion. Only with innovation we can solve the problems of rising fuel costs, rising passenger demand and rising environmental regulations. Innovations used in the WATTsUP will be instrumental in making aviation more sustainable in the long run. As electric drives are scalable, we can expect, that in the future also larger aircraft will use electric propulsion. The world is becoming electric, whether in the air, on land or at sea.”

The serially produced "Alpha Electro" aircraft is an improvement of the "WATTsS UP" prototype. The airframe uses proven features from hundreds of Pipistrel's aircraft flying worldwide.
The electric powertrain is operated with one simple lever, enabling the crew to focus on learning piloting skills! With the smart charger, using the ALPHA Electro is as simple as charging a mobile phone. Even if you only fly for fun and not to train future generations of pilots, the almost silent cockpit, the immediate response of the powertrain and the lack of exhaust emissions will make you feel the pioneering spirit of electric flight.
