Cost categoryPlanning rangeWhat drives it
Electricity$20–$80/hrIllustrative 150–400 kWh billed per block hour at $0.12–$0.20/kWh. Demand charges, charger losses, and peak pricing can increase this.
Maintenance reserve$150–$350/hrScreening allowance for inspections, motors, inverters, rotors, actuators, thermal systems, avionics, high-voltage controls, parts, and technician labor. No leading OEM has published a complete commercial maintenance rate.
Crew and operational control$150–$350/hrPilot, dispatch or flight following, training and checking, records, SMS, and management overhead allocated by flight hour. Autonomous aircraft do not eliminate operational-control obligations.
Ownership, insurance, site and support$200–$600/hrAircraft financing or depreciation, insurance, vertiport or airport charges, charging equipment, software, connectivity, spares, and reserve capacity.
Modeled direct block-hour range$520–$1,380/hrA planning range—not an industry fact. High utilization and simple cTOL operations may approach the low end; low utilization, VTOL cycles, and immature support systems can exceed it.
