The answer is narrower—and more useful—than “electric is cheaper.” A four-passenger eVTOL can win a direct-trip and capacity screen against a regional jet, but the PC-12 is the harder benchmark. The route only becomes a business case when energy, infrastructure, weather, maintenance, certification, and passenger demand all close together.
For each route, the decision should be made in this order: identify the passenger demand by departure, establish the dispatchable payload and reserve requirement, price the complete charging and maintenance system, then compare completion-adjusted cost against the aircraft currently in service.
A route that looks inexpensive at the propeller or rotor is not necessarily inexpensive for a certificate holder. The model must include trained crews, checking, maintenance control, battery condition, charger downtime, aircraft recovery, passenger reaccommodation, and the evidence needed for FAA oversight.

Five eVTOL departures at four passengers provide 20 seats for about $3,475 of modeled direct trip cost; one PC-12 departure provides eight seats for about $1,120. The eVTOL wins only when the community values frequency or demand is genuinely thin.
The electric screen is strong against the regional jet, but not automatically against a one-cycle PC-12. The operator must quantify demand by departure, not average annual enplanements.
Missouri power improves the energy line, but a new STL EAS pattern would need to justify why it is better than the current 30-seat network service to larger hubs.
The stage is short and the current CRJ200 is large. High winds, icing, density altitude, and Denver airspace are more important than the energy arithmetic.
The model favors eVTOL, but the stage is beyond the simple short-hop case. Heat, reserve energy, charging, and payload must be demonstrated, not assumed.
The spreadsheet still favors the eVTOL on direct trip cost, but today this is a concept-development route. A PC-12 or hybrid-electric aircraft is the more credible bridge.
A PC-12 can carry materially more passengers, baggage, and energy reserve in one crew cycle while using existing airport infrastructure and a mature Part 135 maintenance ecosystem. That makes it a better comparison than a 50-seat jet for most thin EAS markets.
The eVTOL has to create value beyond energy cost: more departures, closer access, lower noise, lower local emissions, faster surface-to-air connections, or a service pattern that a PC-12 cannot economically provide. If none of those benefits is present, one PC-12 departure is often the stronger operating choice.
Five changes that can reverse the conclusion.
The eVTOL energy line improves materially, but the total trip cost changes far less than expected because crew, ownership, maintenance, infrastructure, and reserve costs dominate the $650 allowance.
The eVTOL remains attractive against a regional jet on a thin route, but its advantage over the PC-12 narrows. California-style power pricing makes charger utilization and demand charges critical.
Two eVTOL departures are required for the same passenger count that one PC-12 can carry. The PC-12 normally wins the direct operating comparison unless frequency or access creates additional value.
A low direct trip cost can disappear quickly when passengers require reaccommodation, a reserve aircraft, hotel or ground transportation, or protected connections. Completion factor belongs in the base model.
The eVTOL advantage is not free energy. Battery-cycle limits, replacement reserves, charging losses, thermal management, and end-of-life capacity must be allocated by flight hour or cycle.
