July 6, 2023, © Leeham News: In our series on costs factors that make up Cash Operating Cost for a battery-based airliner with range extenders, we now add Crew costs and Airport/Airway fees.

We then have all the components of the Cash Operating Cost (COC) for the ES-30 and can compare it to a normal propulsion 30-seat turboprop.

Summary:

• The high operating weight and slow speed of a battery airliner increase the Airport/Airway fees and Crew costs for the ES-30.
• In summary, only one Cash cost remains competitive, and the COC total exceeds the cost of a 30-seater turboprop.
