VTOL aircraft have the same distance capabilities and make more sense in a lot more scenarios than this, with way more flexibility. It’s obviously larger but I’m just not sure of potential advantages over other modes of transport currently available and in the near future
I'm not so sure. I haven't seen a true regional airline class VTOL yet, mostly just demonstrators that carry a few people, at that. The fact that it's larger is actually very important, the economics of a regional jet replacement make far more sense than that of an air taxi. I also doubt the similar range claim, lifting an airframe directly into the air without wings is far, far less efficient than just taking off with the benefit of lift. They're also way more complex and would require additional training for pilots.
Further, noise restrictions will probably limit VTOL's to airports, never underestimate the NIMBY's. Note that demo videos of eVTOL's almost always have background music rather than ambient sound.
VTOL will not have the same distance capability because the 'vertical' flgiht is the most energy intesive. It's why there's designs like the Beta which transition from VTOL to fixed wing forward flight as soon as they can.
VTOL have other advantages of course in terms of operational flexibility, but where there's existing airfields, fixed electric would be more efficient
Also, at the size/scale of this aircraft (thirty passengers) any type of VTOL wouldd be even less practical
Aren't VTOL aircraft significantly more complex and riskier to operate than fixed-wing prop aircraft? There's certainly many fewer moving parts and tricky transitions from hover to airfoil flight regime.
A quick search of Osprey Class A mishaps puts it slightly ahead (better off) than Blackhawk or Super Stallion.
But a way worse record when compared to the fixed-wing C-130.
Both comparisons are per 100k flight hours.
Some of that risk can possibly be mitigated with a rotating engine, but fixed wing, similar to the Bell Valor. Possibly, because AFAIK, the Valor is the only plane like this and it's just a PoC.
And there’s that whole pesky problem of not being able to glide to a safe landing when something goes catastrophically wrong.
that varies with the design (they could have small fixed wings). Beta have full-airframe ballistic parachutes i believe. That is feasible at least for smaller aircraft.
