eVTOL
Also known as: electric vertical take-off and landing, air taxi, electric air taxi, urban air mobility aircraft
An eVTOL (electric vertical take-off and landing) aircraft uses electric motors and multiple rotors or tilting propellers to rise straight up, fly forward like a small plane, and land vertically.
Companies such as Joby Aviation and Archer Aviation are developing them as air taxis for short city trips. While eVTOLs promise quieter and lower-emission flights than helicopters, certification has taken longer than predicted, battery limits restrict range, and several well-funded companies have already failed.
eVTOL, explained at three levels
At home
Think of a drone big enough to carry people. An eVTOL uses several electric motors spinning propellers to lift straight up like a helicopter. Once airborne, many designs tilt their propellers forward and let wings carry the weight, flying like a small plane, which uses far less energy. Electric motors are quieter and simpler than a helicopter's engine, so the aircraft could hop between rooftops and airports.
At work
An eVTOL is an electric aircraft that takes off and lands vertically and cruises on wings or rotors. Developers such as Joby, Archer, and Beta Technologies aim to run short air taxi, airport shuttle, medical, and cargo flights with less noise, lower operating costs, and lower emissions than helicopters. For businesses and cities, it means planning for vertiports, charging, and new air traffic rules.
At home
Designs fall into three families. Multicopters, like Volocopter's, use many fixed rotors and are simple but inefficient in cruise. Lift-plus-cruise designs use separate rotors for lifting and a pusher propeller with wings for forward flight. Vectored-thrust designs, like Joby's S4 and Archer's Midnight, tilt their propellers between hover and cruise. Spreading lift across many motors means one failed motor need not cause a crash, a property called distributed propulsion.
At work
Commercial service needs four things. The aircraft must earn a type certificate from a regulator such as the FAA, EASA, or Transport Canada, through years of design reviews, conforming test aircraft, and flight tests. Pilots need ratings for the new powered-lift category. Operators need vertiports with high-power charging. Air traffic control needs routes that fit around airports. Early services will be piloted and run on fixed routes, such as airport to downtown, before any autonomous flights.
At home
Batteries store far less energy per kilogram than jet fuel, roughly one-fortieth to one-fiftieth as much, and they don't get lighter as they drain. Hovering is the most power-hungry phase, so every vertical take-off and landing eats into range and the reserve needed for safety. While battery chemistry keeps improving, in my opinion early eVTOL flights will be short, premium-priced hops, not everyday transit.
At work
Certification is the main risk. Each novel design must show the FAA or EASA that it is as safe as existing aircraft, under new criteria for powered-lift, and Transport Canada would need to validate or certify it before Canadian service. Other limits include battery cycle life, cold-weather performance and icing, community noise acceptance, and cash burn: Lilium and Volocopter both became insolvent in 2024. I'd tie infrastructure spending to certification milestones, not launch announcements.
Real-world examples
At home
Sophie read about air taxis that could someday fly from downtown Toronto to Pearson Airport in about 10 minutes. She was surprised to learn the aircraft would be electric and much quieter than a helicopter.
At work
Thomas is an infrastructure planner at a Canadian airport authority. He's assessing where a vertiport with chargers could fit, while noting that certification timelines remain uncertain.
How it compares
| feature | eVTOL | Helicopter |
|---|---|---|
| Power | Electric motors and batteries | Turbine or piston engine |
| Noise | Lower | High |
| Range | Short, roughly tens of kilometres to around 160 km | Longer |
| Status | Certification underway | Mature |
eVTOLs aim to be quieter and cleaner, but helicopters still fly farther today.
For analysts
For transportation planners, eVTOLs are worth planning for but not betting on yet. I'd tie investments to certification milestones rather than company launch dates.
History & origin
Experimental multicopter designs appeared in the early 2010s, helped by advances in drones, lithium batteries, and electric motors. Uber's 2016 'Elevate' white paper popularized the urban air taxi idea, and Joby acquired Uber Elevate in 2020. Billions in investment poured in during 2020 and 2021 as several companies went public. The US FAA finalized rules for training and operating 'powered-lift' aircraft in October 2024. The sector also saw failures: Germany's Lilium and Volocopter both filed for insolvency in late 2024. By 2026, Joby had entered the final stage of FAA type certification and was aiming to begin passenger service in Dubai, with US certification still pending. In my view, eVTOLs are real aircraft with a real future, but the early marketing badly underestimated how hard aviation certification is.
