I am following closely the Volocopter project as the firm that build them also build gliders ( the DGs) and mu clubs own few of the them , so i sometimes go to their factory and watch them.,
The first ones will have to be piloted, , The only model authorized to fly at the moment is the 2 seats 2X model, so only one paying pax. so the early economics based on autonomous flight for 2 paying pax is not there. Plus, unlike now with the prototypes, commercial operations means minimum CPL , so expensive pilots EASA has clearly said no difference for e-aircraft that for current ones,: 30 minutes reserves, which cut OPS range by 60-70% , next is secured Helipad or airfield to Helipad/airfield ,( some called Vertiports) not random front doors to office buildings. Fist live commercial operational ops planned next year Paris for the Olympics. Likely to be VFR ops only. On fixed special designated routes . Rules on overflying large number of people still unclear. Current trials flights in Pontoise airfield to validate the concept.
So in Europe at least , not that simple.
