Distributed electric propulsion in a new design seems to offer most in the way of improved aerodynamic efficiency as well as structural benefits and weight saving. Retrofitting an existing (old) design like the Beaver with electric propulsion significantly reduces noise, which is a real advantage when operating a floatplane from urban harbour areas like Vancouver and Seattle, - albeit a niche application.

The electric Pipistrel apparently offers great cost advantages compared with an IC basic trainer, as much of it's life is spent in the aerodrome circuit with students at the controls (circuits and bumps!), - or 'pattern' as our American cousins call it. Quieter too, so another niche application for a full sized electric aircraft.

So the driver here is not necessarily carbon reduction but operating cost and noise reduction.

More significant progress on the full size electric front.

eCaravan

Some very significant progress too in terms of providing redundancy in the motor and power supply. This outfit certainly appear to have their act together whilst pushing the boundaries...

I saw the news about an electric airliner. It is scheduled to fly soon and will do one hundred miles. Brilliant. Right lads, who's for avtur?

There are a good number of short hop flights around the world for which the electric Cessna Caravan would already be the best solution. For passenger safety, propellers must be stopped when boarding and disembarking, which drastically shortens the service intervals on turboprops; hence the reason Aurigny in the Channel Islands hung onto their piston-engined Trislanders for so long. Air-cooled piston engines have their own problems with lots of starting and stopping, so on short inter-island routes electric aircraft are already at an advantage. Two or more motors would be desirable though as electric motors, and speed controllers do fail.

The 90 second Westray/Papa Westray route may be the first to be electrified in this country, Loganair were toting this a couple of years ago, and with the help of Cranfield Aerospace are converting one of their Islanders.

That's really interesting about the BN Islander. I'd love to see a full size leccy one as it's one of my favourite aircraft.

Lots of good stuff going on in Orkney generally in terms of renewables, use of hydrogen for ferries etc. Fully Charged on YouTube have done two or three programs up there that are worth a look.

Fully Charged have an annual show for all things electric/renewables which this year was supposed to be at Farnborough. All electric aircraft were supposed to be exhibiting for the first time. Hopefully it will take place in the near future.

Cheers

Postponed until next year now, probably wisely.
