17-499: The Pipistrel Velis Electro is a Slovenian light aircraft , designed and produced by Pipistrel of Ajdovščina . The aircraft was EASA CS-LSA fully electric type certified in June 2020 and it is intended primarily for the training aircraft role, particularly multiple successive take-off and landings at the airfield . The design is the first type certified electric aircraft and is supplied complete and ready-to-fly. The aircraft
34-508: A certification period of just under three years. The short time frame for the first certification of an electric aircraft was attributed by EASA to "close co-operation" between the manufacturer and the agency. The design was approved as a variant of the Virus on the same type certificate and is officially designated by EASA as the Virus SW 128 (Velis Electro) . The aircraft is in production and
51-659: Is based on the Pipistrel Virus airframe and features a cantilever high-wing , a two-seats-in- side-by-side configuration in an enclosed cabin accessed via doors. It has a stick shaker and fixed tricycle landing gear and a single electric motor in tractor configuration . The airframe is predominantly made from composite materials . Its 10.71 m (35.1 ft) span wing, has an area of 9.5 m (102 sq ft), an aspect ratio of 12.03:1, an IMD 029-b airfoil and mounts three-position flaps , with settings of 0°, 8° and 19°. The sole approved powerplant
68-403: Is mounted in the nose and one behind the cabin for balance . They take 2 hours to recharge from 30% to 100% capacity, and allow an endurance of up to 50 minutes plus 10 minutes of VFR reserves when flying in proximity of the aerodrome. The motor radiator is mounted in the nose, which necessitates a different engine cowling from the Virus design. The battery radiator is mounted in the rear. Due to
85-457: Is published on a monthly basis and serves as the flagship journal of the society. In January 2015 the Journal of Guidance, Control, and Dynamics became the second AIAA journal published on a monthly basis. The other journals are published bi-monthly and have more specialized topics: AIAA's flagship magazine Aerospace America was started in 1990 and is distributed monthly to all members, and
102-464: Is published online in digital format. AIAA also produces several series of technical books ranging from education to progress in advanced research topics. AIAA annually holds design competitions and Design/Build/Fly competitions to provide a real-world design experience for engineering students, both undergraduate and graduate, by giving them the opportunity to validate their analytic studies. AIAA hosts many conferences and smaller events throughout
119-469: Is the first certified electric aircraft motor and was certified by EASA on 18 May 2020. The Velis Electro has a maximum noise level of 60 dBa . The aircraft has an empty weight of 428 kg (944 lb) and a gross weight of 600 kg (1,300 lb), giving a useful load of 172 kg (379 lb). The design received its European Union Aviation Safety Agency (EASA) type certificate for day, visual flight rules operations, on 10 June 2020, after
136-552: Is the liquid-cooled Pipistrel E-811 electric motor , rated at 57.6 kW (77 hp) at 2500 rpm for 90 seconds for take-off and 49.2 kW (66 hp) at 2350 rpm for continuous operation. The motor was developed in conjunction with the Slovenian engineering companies Emrax and Emsiso . It is powered by a 345 VDC, 20 kWh battery pack, in two 70 kg (150 lb) each, liquid-cooled lithium batteries by Pipistrel, connected in parallel for fault tolerance . One battery
153-651: The "2020 Plane of the Year". In August 2021, the Velis Electro received the 2021 AIAA Aircraft Design Award. The Velis Electro is one of the winners of the 2021 Aviation Week Network 's Laureate Awards in the category Business Aviation.

In August and September 2020, a group of Swiss electric mobility enthusiasts with support from the manufacturer flew a Velis Electro on a series of flights intended to be accepted as world records. Records were claimed for the lowest energy consumption (22.76 kWh/100 km), the highest average speed over a 100 km (136 km/h) and a 700 km (125 km/h) route, longest electrically flown route over 24 hours (327 km), 48 hours (608 km) and 56 hours (839 km). The Pipistrel Velis Electro has received several awards since its introduction. In November 2020, Plane & Pilot Magazine named it
