My post was cut short, but before that happened I made a copy of the complete post and it is reproduced ( I hope! ) in its entirety. If anyone can delete my original incomplete post then I would appreciate it. My effort to do so was unsuccessful. Okiedo

Pavel, I am going to challenge you on this issue.. the future of electric powered commercial aircraft. I don't think you are seeing the benefit to the airlines for short hop development where electric powered commercial aircraft transporting numbers in many instances far exceeding the arbitrary number of 1-3 passengers plus 1 pilot that you state in your post. Commercial short hop routes have the potential to be expanded to serve smaller airports that have been essentially lost to commercial aviation by the development of nearly all jet engine powered commercial transport. Europe, where you live, is a prime example in this future for electric powered short distance commercial airplane development.
To wit:
"In Norway, where the countries expansive fjords and rough terrain make air travel more efficient than road, the government is making an impressive pledge. It announced that by 2040 all its domestic flights will be electrically powered. In a country where the shortest internal flight is 12 minutes – the same journey taking several hours by car, the initiative could revolutionize everyday flights.
The advancement of urban air mobility will also demand new infrastructure in cities. Uber Air recently announced a partnership with Signature Flight Services to develop a ‘Skyport’ infrastructure. The first location will be in California in association with real estate developer Related Companies."

So, in the U.S. how does the FAA analize the future of regional electric powered commercial aviation?
“Electric propulsion for aircraft has the potential to be a real game-changer for general aviation,” said Thomas Gunnarson, a transportation industry analyst with the FAA’s Aircraft Certification Service in Kansas City, Missouri. “We may be behind where the auto industry is on this now, but we’re gaining ground quickly.”
Gunnarson is part of the Programs and Procedures Branch in the Small Airplane Directorate that specializes in studying innovative applications of technology to improve safety and reliability for general aviation. “We’re looking at the total package that electric propulsion technology can bring us,” said Gunnarson. “Before it can be implemented, however, we must first determine if it is safe, economical, and practical in the aviation environment.”

Pavel, you should "meet Alice" a 9 passenger, 2 crewmember commercial plane. NBC's Today show reported on 15 April of this year, 2022, the following:
A battery-powered plane nicknamed Alice made by Israeli company Eviation may be the future of air travel. First test flights are expected this summer, with planes in service possibly within two years – and some companies have already put in large orders.
Eviation is the Israeli company working on Alice. See their website and the video there about Alice:

What percent of global fliights today are less than 100 miles and amenable to regional aviation technological developments such as electric powered commercial airplanes?
The paragraph below addresses that question:
MagniX CEO Roei Ganzarski believes airlines such as Harbour Air would prefer to convert existing planes instead of spending millions to buy new all-electric aircraft. According to him, last year, 5 percent of global flights — not including cargo and private flights — were less than 100 miles. "All of the aircraft used for these flights are perfectly suited to conversion," he’s quoted as saying.
And also:
Air Tindi, which operates scheduled and charter flights to remote communities across northern Canada from its base in Yellowknife in the country’s Northwest Territories, will provide one of its 50-seat Dash 7 aircraft to be retrofitted and available for flight testing. This will be powered by its existing Pratt & Whitney PT6 engines as well as a pair of MagniX’s Magni650 electric propulsion units.
MagniX is already working on plans to convert the smaller Beaver and Caravan aircraft to electric propulsion in partnership with operators such as Vancouver-based Harbour Air. It is also providing electric motors for its sister company Eviation’s new nine-passenger Alice aircraft.
Pavel, read again that part above about converting a 50 seat Dash 7 aircraft to electric power. I believe that 50 passengers exceeds your arbitrary number of 1-3 passengers with 1 crewmember by a considerable per cent, but I will let you do the math. No, the Dash 7 conversion is not a fait accompli yet, but they are working on it now as noted in the article linked below:

Drawing your attention, Pavel, to the following paragraph about the future of short-haul aviation, which is linked hand and glove to the future of electric powered commercial aviation:
"Two forces are now taking hold that will dramatically change the short-haul aviation market: a change in the demand for short haul travel; and the rapid advance in electric aviation technology. In a post-COVID world, employees increasingly will work and live in remote locations, reducing the need for short haul travel. Meanwhile, the economics of electric aviation are becoming more feasible. Electric aviation has the potential to change consumer travel behavior, moving travelers out of cars and into low-carbon or zero-carbon emission quiet aircraft. This will result in lower costs and shorter travel times while using existing small airport infrastructure."

The development of the jet engine in commercial airline application was pretty much the death knell for short haul aviation in the past and for small regional and sub-regional airports. It was just too expensive to service these airports with commercial planes powered by expensive jet powered planes, but the development, and yes it is still "developing", of commercial electric powered aircraft is going to reverse that process and bring the dead back to life, certainly in many applications in Europe and also here in the U.S. as well as all of North and South America. What better way to breathe new life into the corpse of short haul aviation than to do it "electrically"!

A completely different angle on the subject of electric powered commercial aircraft that both you and I have ignored is that area in between combustion engine aviation and pure electric aviation: Hybrid Electric Aviation. It also has a niche of its own in the future of aviation. As an example:

In summary, Pavel, in my opinion your restriction to a scenario allowing for only 1-3 passengers plus 1 pilot paints a picture of electric powered commercial aviation that is completely incongruent with the facts. JMO
