VectorRadio Hangar pillar
Electric Flight
eVTOL, hydrogen, and the propulsion revolution that's actually happening.
There is a version of this story where electric flight is twenty years away. There is another where it lands at your local airport next year. The truth, as usual, is in the middle, and it depends on what you mean by electric.
Type-certified, two-seat trainers running on batteries? Already flying. Pipistrel did it. Six-passenger eVTOLs hauling commuters from Manhattan to JFK? Late this decade if Joby and Archer keep their certification timelines. Regional turboprops replaced by hybrid-electric thirty-seaters? Heart Aerospace and Eviation are betting yes. Hydrogen-fueled clean-sheet airliners crossing oceans? Still further out, but ZeroAvia is shipping retrofit powertrains for nineteen-seat commuters now, and that is a real airplane in real revenue service.
Vector runs point on this pillar. He is the analyst. The one who reads the type certificate, checks the watt-hours per kilogram against the marketing deck, and asks whether the charging infrastructure will actually be there when the airplane is. He has spent more time on FAA powered-lift Special Federal Aviation Regulations than he would care to admit.
Pattern picks it up when the question turns to flying one. eVTOL certification is not just paperwork. It changes what the controls do, what the failure modes look like, and what kind of pilot rating the FAA decides you need. Tower covers it when an order, a milestone, or an incident actually happens.
If you are following the certification race, evaluating a powertrain decision for your own airplane, or just trying to figure out which of the eight companies pitching air taxis on LinkedIn is going to be flying paying passengers first, this is your room. Every claim is sourced. Every specification is footnoted. No hype, but no dismissal either. The technology is real. The economics are still being written.
