The Eviation Alice, Cape Air's Seventy-Five Aircraft Order, and the Energy Density Math That Determines Whether Electric Commuter Aviation Can Actually Work

On September 27, 2022, the Eviation Alice lifted off from Grant County International Airport in Moses Lake, Washington and flew for eight minutes - the first time an all-electric multi-passenger commuter aircraft had flown anywhere on the planet. The flight was short by design, but the milestone was genuine. Understanding why it matters, and what stands between that first flight and routine commercial service, requires working through the energy math that most coverage ignores.

What the Eviation Alice Actually Is

Eviation Aircraft is an Israeli-founded company that relocated development operations to the Pacific Northwest. The Alice is a nine-passenger, two-pilot commuter aircraft built as a clean-sheet design from the start. The airframe is all-composite with conventional tricycle gear. Two electric motors - one on each wing, driving composite tractor propellers - replaced the combustion powerplants entirely. The electrical energy comes from a lithium-ion battery pack with a total capacity of approximately 820 kilowatt-hours.

For scale: a current-generation electric car carries a battery pack in the range of 60 to 100 kWh. The Alice carries roughly ten to twelve times that energy just to move nine people a few hundred miles.

The original design called for three motors - two at the wingtips in tractor configuration and one in the tail as a pusher. By first flight, that had changed to the two-motor wing-mounted layout, developed in partnership with GE Aviation. That partnership matters beyond the hardware: GE brings certified propulsion experience and regulatory credibility that a startup motor manufacturer cannot offer. Having GE’s track record on the powertrain fundamentally changes the nature of the certification conversation with the FAA.

The Energy Density Problem Every Pilot Should Understand

Electric motors are genuinely well-suited to aviation. Maximum torque from zero RPM, few moving parts, no combustion, no hot section, no turbine blades demanding exotic alloys and precisely timed inspection intervals. The mechanical case for electric propulsion is strong.

The constraint is energy storage.

Jet-A fuel contains approximately 12,000 watt-hours of chemical energy per kilogram. That is the energy density that allows an airliner to carry hundreds of people across an ocean. The best commercially available lithium-ion cells today store 250 to 300 Wh/kg at the cell level. Once you add cooling systems, thermal management electronics, the battery management computer, structural housing, and electrical interconnects, a full aviation-grade battery system achieves roughly 180 to 200 Wh/kg at the system level.

Jet fuel stores approximately 40 to 60 times more energy per kilogram than a practical aviation battery system. Not 40 to 60 percent more. Forty to sixty times more.

For aviation, where every kilogram either lifts payload or robs it, this is the defining constraint of the electric era. It is a chemistry and materials science problem - not a software problem - and progress is measured in years and decades, not quarters.

Why Short Routes Change the Math

The Alice is not attempting to replace a turboprop on a 500-mile sector. Eviation’s published range figure is approximately 440 miles, but that number almost certainly reflects ideal conditions: optimal altitude, optimal temperature, minimal wind, and a payload that may not represent a fully loaded nine-passenger manifest with bags. Operators building actual schedules will use the conservative number.

The practical target range for real-world commercial operations is approximately 200 to 250 miles. At that distance, the energy math becomes manageable. The fundamental limitation shifts from a show-stopper to a design parameter, which is exactly where the Alice’s most important customer operates.

Cape Air’s 75-Aircraft Order and Why It Makes Sense

Cape Air is one of the most interesting regional carriers in the United States. They connect small New England and Great Lakes communities to hub airports - Boston to Nantucket, Boston to Martha’s Vineyard, Portland to Rockland, Provincetown to Logan. Cape Air’s average segment length is well under 150 miles, and many routes are under 50.

Cape Air placed an order for 75 Alice aircraft. Their current fleet is predominantly Cessna 402s - piston twins that have been in continuous service for decades. On a 50-mile hop, the operating economics of an aging piston twin are difficult. Fuel costs, oil changes, cylinder overhauls, prop overhauls, engine replacements: the cost structure is genuinely burdensome for high-frequency short segments.

The Alice’s value proposition is straightforward. Electric motors require far less maintenance than piston engines. Electricity on a fixed commercial rate contract offers cost predictability that jet fuel never will. For an operator running the same route six times a day with a fleet of 75 aircraft, those savings accumulate into numbers that get a CFO’s attention quickly.

What the Constant-Weight Flight Profile Means for Pilots

In a conventional aircraft, weight decreases as the flight progresses. A Cessna 172 departing full arrives 40 to 50 pounds lighter. An airliner on a long-haul route may burn a substantial fraction of its total takeoff weight. As weight decreases, performance improves: climb rates increase, structural loads at landing are lower than at takeoff, approach speeds decrease.

None of that happens in the Alice.

The battery pack that discharged during the flight is still physically mounted to the airframe when the wheels touch down. The Alice lands at almost exactly the same weight it took off. Every performance calculation - from the takeoff roll through obstacle clearance through approach and landing - is made at the same gross weight number, on both ends of the flight. Runway requirements on arrival equal runway requirements on departure. Brake energy demands are not reduced.

The divert calculus also changes. In a conventional aircraft, a divert to an alternate burns fuel but lightens the aircraft. In the Alice, a divert spends from a fixed energy budget. Pilots need to know exactly how much capacity remains, how much the divert will cost, and whether reserves are sufficient. Energy state awareness becomes a central discipline in a way it typically is not in piston or turbine flying.

The Certification and Infrastructure Challenges

There is no existing FAA type certification framework that a nine-passenger all-electric commuter fits cleanly into. The regulations written for piston twins and turboprops were designed for combustion powerplants with well-understood failure modes and decades of service history. Electric propulsion introduces different failure profiles, different redundancy philosophies, and different performance characteristics in degraded states.

The FAA is developing appropriate standards as the program matures, working with Eviation rather than applying a pre-existing template. This is not unprecedented - the FAA has done it before with truly novel configurations - but it means the certification timeline carries real uncertainty. A realistic entry-into-service window is the second half of this decade, assuming testing continues to progress.

The infrastructure challenge is equally significant and less frequently discussed. Regular commercial service requires high-capacity charging systems at every turn airport on the route network - not a standard hangar outlet, but commercial-grade, high-voltage installations capable of bringing an 820 kWh pack to operational charge within the available turnaround window. For large hub airports, this is an engineering project. For the small regional airports that define Cape Air’s network, some of which have minimal ground power capacity, it may require utility upgrades and substation work well beyond the cost of the aircraft order itself.

Cape Air has acknowledged this publicly. The infrastructure equation is part of the program, not a footnote, and it will determine which routes the Alice enters first and at what pace the fleet actually deploys.

The Broader Electric Regional Aviation Landscape

The Alice is not the only program working this territory. Harbour Air in British Columbia has been flight-testing an electrically converted de Havilland Beaver on its float route network. Heart Aerospace in Sweden is developing a hybrid-electric regional aircraft targeting routes in the 30-passenger range. The approaches differ, the timelines differ, and the operating philosophies differ - but all are converging on the same conclusion: short-haul regional aviation under 200 miles is the most fertile ground for electric propulsion, because it is the only segment where current battery technology can actually meet the range requirement.

Why This Matters for the Regional Air Transportation Network

The communities on Cape Air’s route network depend on short-hop air service to stay connected to the broader transportation system. The major carriers largely abandoned these markets years ago. The operators that serve them are running aging piston equipment at difficult economics, on routes that matter enormously to the people who live there.

The Alice is specifically designed for that gap. Its limitations are real, but they are manageable within that mission. The constant-weight flight profile is a design constraint pilots can plan around. The range numbers fit the routes. The charging infrastructure challenge is solvable - capital-intensive and time-consuming, but solvable.

Whether the program ultimately succeeds depends on execution: completing certification, building out infrastructure, and proving that the battery pack degrades gracefully in real commercial service rather than catastrophically. Those are open questions with genuine uncertainty attached.

But the first flight happened. Eight minutes over the high desert at Moses Lake on September 27, 2022 was the opening move in what will be a long game for electric aviation at the passenger-carrying scale.
