Green Aviation: Tested on an electric-powered Orkney.

Scotland’s first hybrid electric aircraft took to the skies at a new test center in Orkney.

Umpire, a US-based aviation company, has replaced one of the piston engines in its Cessna aircraft with a compact electric motor.

The umpire believes that hybrid technology can pave the way for shorter trips with inter-island and green technologies.

After initial test flights in Hawaii, the plane was sent to Scotland for its first open-air flight. A 90-minute fast charge of an aircraft battery can provide an hour’s flight.
