Pipistrel Virus Sw 121

Single Electric

The Pipistrel Velis Electro holds a singular distinction in aviation history: it became the world's first type-certified electric aircraft when EASA granted approval in June 2020. Built by Slovenia's Pipistrel Aircraft, the Velis Electro is a two-seat trainer derived from the company's proven Alpha platform, re-engineered around a 57.6 kW electric motor and twin lithium-ion battery packs. With zero direct emissions, near-silent operation, and operating costs a fraction of conventional trainers, it represents a watershed moment for flight training and the broader push toward sustainable aviation. The aircraft's certification marked the end of a multi-year validation effort that required EASA to develop entirely new standards for electric propulsion, battery safety, and energy management systems — regulatory groundwork that will shape the next generation of electric aircraft. In service, the Velis Electro offers flight schools an economically compelling and environmentally responsible alternative to legacy piston trainers. Its 50-minute endurance plus reserve suits the typical lesson profile, while the electric powertrain eliminates magneto checks, spark plug maintenance, and avgas dependency. Maximum takeoff weight is 1,320 pounds, cruise speed approximately 90 knots, and the aircraft's docile handling mirrors its Rotax-powered predecessors. Range limitations and charging infrastructure remain practical constraints, but early adopters across Europe and North America have validated the type's viability for ab-initio training, particularly at airfields facing noise restrictions. The Velis Electro's certification has catalyzed a wave of electric aircraft development, proving that battery-electric flight is no longer experimental but a certified, operational reality. SkyMeter has tracked 8 flights across 4 airframes and 2 operators, with SOA HOLDINGS LLC the largest observed operator.

Safety in context

The incident rate counts flights with ANY safety event detected by SkyMeter — go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
