Equator Aircraft's P2 Xcursion prototype electric amphibious aircraft has taken fully to the air for the first time in the skies over Eggemoen Technology Park in Norway. The two-seater, composite-hulled airplane operated by test pilot Eskil Amdal had previously flown at a low-altitude, ground-effect flight in June 2018 and went into full flight on March 30 of this year after passing an audit by the Norwegian CAA.

The 10-minute flight was conducted under electric power only as the aircraft was put through maneuvers to test controllability, as well as static and dynamic stability. According to the company, the P2 Xcursion performed as expected and returned data that can be used to improve the design.

The prototype flew only using its 97 kW ENGIRO M97 powered by lithium-ion batteries weighing 100 kg (220 lb), giving it a total flight endurance of about 35 minutes. However, Equator Aircraft says that later versions will be able to stay aloft for 105 minutes and when it kicks in its Energio generator and Wankel diesel engine to provide electricity, it will be able to cruise for up to six hours.

The P2 Xcursion is designed to be not only affordable, but also to have an unusually roomy cockpit that can carry two people plus a generous amount of luggage. Instead of floats, it uses a fuselage that is self-buoyant and float wings that also provide greater stability. The blended fuselage with a retractable undercarriage is streamlined and the canopy and airfoils reduce drag.

In terms of the numbers, the P2 Xcursion with its composite construction weighs only 750 kg (1,653 lb), yet can carry a payload of 240 kg (529 lb). It has a maximum cruising speed of 130 knots (150 mph, 241 km/h), and a maximum range of 845 nm (972 mi, 1,565 km).

"It was a fantastic day for the team, and marks finally the continuation of the test program for the aircraft prototype, says Designer and CEO Tomas Brødreskift. "We are now looking forward to gaining actual flight data, and not to mention look forward to putting the aircraft on the water as soon as possible. We are thrilled to see the aircraft perform as expected, and can't wait to test the aircraft further."

The video below shows the first full flight of the P2 Xcursion.

Were the diesel and generator carried as dead weight or will they reduce payload when added?

I think I'd prefer the ground-effect over water version.

Great accomplishment and specs. Hope to see it affordable in kit form.

Oh great! A diesel generator to extend flight time!

Aside from the fact that I have always liked amphibious aircraft this is the future of "electric" aircraft. 100kg of batteries giving an endurance of 35 minutes may sound laughable but coupled with a Wankel diesel engine powered generator makes for, potentially, some very efficient flight. Also with a puller prop mounted on a high tail possibly some very low cockpit noise levels. The engine only needs to kick in for cruise, charging the batteries to full at the same time, leaving you thirty odd minutes of electric powered flight in the event of engine failure. The P2 Xcursion looks to be a slick design borrowing from some highly successful past amphibians like the Lake Buccaneer. I am normally highly cynical about any form of electric flight for the obvious energy density to weight problems but coupling a Wankel engine to a generator is a genius combination that should make for a compact, highly efficient, quiet power plant. I will be following the development of this aircraft with great interest.

What a pretty little airplane! Looks like a blast to fly!

Pretty bird! That looks like a handy plane for the Scandinavians, with all their fiords (Drove my Ford to the fiord, but the fiord was dry) up there. The specs seem too good to be true. I wonder how quickly airports will adapt to provide charging stations for e-aircraft.
What's the deal with the Wankel diesel and Energio generator? Could that be installed in an electric car for 2k mile range? More info, please.
And oh, dear God, I hate it when they use the A word. (affordable) It usually means "I'm going to grab your wallet and run!"
Happy Earth Day, y'all!

Very cool! But is a low wing a good idea on a water landing airplane? Isn’t it more likely to catch a wave that way? Educate me please.

I think that is both cool and green. It is - IMO - a beautiful design.
It indicates a Wankel engine? I know that Liquid Piston has a similar style engine that they are working on. I believe it can run on a variety of fuels.
Intelligent Energy has some compact fuel cells. I wonder if that would work with this design?
