Electric aircraft could transform short-distance regional air travel
Whenever the subject of electric aircraft comes up I see the room filled with skeptical looks. The looks are not unwarranted. Even electric cars remain in the low single digits for worldwide market share and electric flight is undoubtedly a greater hurdle. The enemy of flight is weight after all and batteries are rather heavy. The skepticism though, while justified, is misplaced.
The problem is that we tend to think of air transport as large intercontinental craft flying thousands of miles at a time. Those certainly exist and there’s even one that travels 9000 miles, flying 17 hours from Perth to London. The reality for most air travel, however, is somewhat different. Statistics from the US Bureau of Transportation show that the overwhelming majority of US passengers are on domestic flights and what’s more, nearly half of those are under 700 miles.

The data graphed above shows that 20% of domestic passengers are flying under 350 miles in the USA, with nearly 50% under 700 miles. Forget about the 9,000 mile international flights, this is the market for electrified flight in the near-term. The aircraft to support it are nearly here.
I’ve written in the past about the various electric aircraft in development from companies like Zunum Aero, Wright Electric, Airbus/Siemens, NASA, Eviation, BYE, and others. It’s still very early but advancement is steady and the age of electric flight is coming. For a moment consider Zunum Aero’s aircraft, the ZA10. It’s a 12-seat hybrid for regional transport, slated to begin test flights next year and deliveries in the early 2020s. The aircraft is targeting a range of 700 miles and will have a shorter range all-electric version. There’s also a larger variant planned.
Zunum Aero’s ZA10

- 60 to 80% reduction in operating costs
- 80% lower emissions and noise
- 40% reduction in runway needs
- Hybrid-electric range of 700 miles
Back to those skeptical looks. The financial driver for electrification is huge, with the potential to reduce operating costs 60 to 80%. More so with carbon pricing. If said hybrid aircraft also create less pollution, require shorter runways, reduce maintenance, and produce less noise, well then which carriers wouldn’t want to use them? Particularly in a regional market which, as noted previously, includes nearly 50% of all domestic flights in the US.
That all seems great, but even this understates the impact of electrification. What’s missing from the analysis is the potential for electric aircraft to fundamentally transform air travel as we know it, to vastly increase the number of flights under 700 miles.
The data we have today shows us the past, but this is the future:
Electric and hybrid aircraft have the potential to open up new regions to air travel, revitalize small neglected airports, create jobs in small communities, and make travel more enjoyable for everyone. This vision will become a necessity if we hope to have a cohesive society and growing economy,
“In the globalized economy, communities without good air service struggle to attract investment and create jobs” – Zunum Aero
There’s a wonderful write-up on IEEE Spectrum which highlights how electrification can be the catalyst that rejuvenates regional travel. The article’s authors are from Zunum Aero, including the founder and the chief technology officer.
The article includes some interesting statistics on the current state of air travel. For example, the authors note that only 1% of the airports in the USA are responsible for 96% of the air traffic and that since 1980 the average aircraft seat capacity has increased by a factor of 4. What if electric aircraft can increase travel to just some of those other airports?
The current state of air travel is largely the result of financial choices made over many decades. Larger aircraft are more economical to purchase and operate, while fewer routes keep aircraft load factors high and simplifies logistics.
“Regional Travel is Ripe for Reinvention” – JetBlue Technology Ventures
The problem with this is that large airplanes require large infrastructure to support them (think space, buildings, runways) and the noise they generate is not well liked by residents. There aren’t many airports able to accommodate these needs so people are funneled to major airports located outside of major cities, sometimes inconveniently out of the way of the passengers’ ultimate destinations. This means more time is spent traveling to the airport, at the airport, and flying on the airplane, for an experience that is all to often chaotic and impersonal. In fact, door to door travel times have actually gotten worse for regional air travel, not better. Add in a snowstorm or a single large aircraft is delay and it can become a logistical nightmare.
The benefits of electric aircraft are particularly well suited to regional air travel needs. The question is, will it be enough to usher in a renaissance for regional flight, where smaller aircraft travel more routes and to smaller airports? I certainly think so. Toronto has a great example of how this might occur. The Toronto Island airport can only operate small aircraft due to noise restrictions, but it’s use has grown steadily. It’s accessibility from downtown and the spectacular speed of service are key drivers. With electric aircraft I believe this type of scenario will become the norm.
Now, what if you could do it from your own front door?
Hyper-local air travel with electric vertical takeoff and landing aircraft (E-VTOL)
Imagine this. You wake up in the morning, dress, open your phone and request an electric vertical takeoff and landing aircraft (VTOL) to take you to a city a few hours drive away. An electric autonomous car picks up you and drives you to a local VTOL access point, on top of a parkade near your home. Several small two and four seat aircraft are waiting there. Maybe someone is there to greet you but it’s only customary. Your phone recognizes your access and opens up the passenger compartment to your aircraft. You get in, there is no pilot, no cockpit – the vehicle is autonomous. Quickly the electric motors spin up, the craft rises into the air and carries you directly into the centre of a nearby city. Or maybe you go to a remote campsite or to an airport outside of the city where you can access an intercontinental flight. All of this for a cost less than traditional means of transport.
Long have we been promised a future of flying cars, but this time electric propulsion and increased autonomy can actually make it happen. Check out the video below of the first full scale test flight of the Lilium Jet in 2017. Such ideas were once confined to science fiction, but no more. Yes, this technology is in the early stages and it remains to be seen how far batteries can take us. Yet those batteries get better each year. For Lilium’s part they have manned test flights coming next year and they are targeting a range of 300km and speed of 300km/hr. That could open up a whole new type of air travel.
Electric VTOL – Lilium
Lilium started in 2013 with the vision of developing an all-electric “air-taxi” vehicle.
There are now dozens of companies working on electric VTOL aircraft, with over 100 projects underway. Norway’s aircraft operator Avinor even issued a report earlier this year that sees a path to small VTOL aircraft with 1 or 2 passengers in the early to mid 2020’s, with larger 4 or 5 person craft reaching market by the end of the 2020’s.
The fascinating world of VTOLs aside, fixed-wing hybrid and electric regional jets provide an obvious path for electrification. This will reduce operating costs, open up new opportunities for passengers, and reduced the environmental impact of flying. It’s where corporations and countries are already going. Norway for example has a target of 2030 for all regional flights to be fully electric, not hybrid, fully electric. While operators and manufacturers are pushing to see who can take the lead. One thing is certain, with the coming advancements in electric flight regional transport will never be the same.

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.

Tesla updates Cybertruck owners about key Powershare feature
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
