First, there’s Joe Scott’s take on a brief history and the current state of electrically-powered aviation along with some of the challenges that we all, socially and culturally, will need to overcome:
Are they doomed? That depends entirely upon what you consider to be “required” for an electric aircraft.
Next, there’s Pipistrel (Wiki), a Slovenian light aircraft manufacturer who has entirely-E-powered Velis Electro intended for training purposes. In fact, they have received, shockingly, the very first-ever Type Certificate from EASA — the European Aviation Safety Agency.
It’s only a matter of time until an eager aviator (or two or three) purchase and import a Velis registered as an Experimental Aircraft. Note that the Pipistrel Alpha is certificated as an Experimental or LSA already in the USA (ca. US$175,000, more or less as an LSA).
No Type Certificate for the Velis in the USA…
Give it time.
