The article discusses the current state and future prospects of battery-based aircraft and electric Vertical Take-Off and Landing (eVTOL) vehicles in the aviation industry. Battery-powered general aviation aircraft like the Pipistrel Velis Electro and Diamond eDA40 trainer are highlighted for their suitability in pilot training, offering advantages such as ease of preparation, reduced noise, and emissions. However, their limited mission time and certification for Visual Flight Rules (VFR) only pose challenges for advanced training and long-distance flights. The article points out that advancements in battery technology, potentially by 2030-2035, could enable small commuter aircraft to operate on routes of 200 to 300 nautical miles with improved endurance and safety reserves. Regarding eVTOLs, the focus is on their current operational limitations, such as VFR day-only certification and restricted capabilities compared to helicopters. While they show promise for short-distance shuttle services like airport-to-city-center routes, their market expansion is hindered by factors like weather conditions and endurance challenges. The analysis suggests that the eVTOL market will grow gradually as technology evolves to meet the demands of longer flights, Instrument Meteorological Conditions (IMC), and Flight-Into-Known-Icing (FIKI) situations. The article provides a practical example of the Nice Airport to Monaco route to illustrate the potential market for eVTOLs in replacing helicopters in select scenarios. Overall, the article portrays a positive outlook on the future of battery-based aircraft and eVTOLs, emphasizing the need for technological advancements to enhance their operational utility in air transport.
