“…Ampaire, a pioneer in hybrid electric aircraft technology, launches demonstration flights between Exeter Airport and Cornwall Airport Newquay this week, to advance the use of sustainable aviation, driving down costs and emissions on short regional routes.  The flights are part of a series of government-backed trials aimed at moving the UK towards green aviation. Demonstration flights will be flown by its Electric EEL technology aircraft.  The EEL, a modified US-built six-seat Cessna 337 Skymaster, features a battery-powered electric motor at the front and conventional combustion engine at the rear, enabling a reduction in emissions and operating costs by as much as 30%.  The aircraft will fly between these two regional airports, 85 miles apart, on a combination of battery and piston power, collecting valuable data to monitor fuel savings, efficiency and noise…”
