If the max speed is 287 miles/hr, and it has enough battery power to fly for 1 hour, it could not fly more than 287 miles, or 460km. Why does the video claim 815km range?

@@Alven1111 Since it only has power for 1 hour (presumably thats at most efficient speed), then flying slower would mean even less range. If it flew at 400 kph, that would take over 2 hours to reach that 815 km range. Someone clearly goofed at their math... or exaggerated.

It’s “coming into service”? They are converting their “whole fleet”? They converted one airplane and as far as I know they flew it once. The cost of that conversion was most likely horrendous. There is no indication that they are in the process of converting even one additional airplane. I expect the test results show that the current configuration is not viable. So spare me your hype - it is complete bull crap. You’ve been completely sucked in by press releases

I know the difference in energy density between lithium batteries and 100LL av gas. This beaver is a technology demonstrator, not a practical airplane. Not yet.

Your maximum speed of 287 MPH and 1 hour of flight time of 815 KM do not add up. If you can only fly one hour, and you can travel 815 KM, your average speed would be 506 MPH. far in excess of the 287 MPH. Either your flight time or range quoted in the video is an error.

This is a great Israeli company (now Israeli-Singaporean), and hopefully they succeed. It's perfect for some routes in Israel between regional inactive or semi-active airstrips, like a route from Tel Aviv to Kiryat Shmona. However, at these distances the plane also competes with buses for cost, so they (or the airlines) will really need to work out the business model. Granted, in some countries there are short-distance flights that go over straits or other places where land vehicles cannot pass. However, most of those routes are subsidized, like the Cape Air routes. This is also not a good long-term business model. If they manage to build that 40-seat version, it could really be the future of short-haul aviation.

The endurance is never quoted at max speed. It is quoted at the speed for max endurance, which is way slower. And any range numbers have to include a 45 min reserve. That would put the aircraft’s real endurance at 15 min probably at 200mph or less IF these promised numbers turn out to be true, which they most probably are not

Hydrogen Fuel Cell (HFC) technology is being considered. Compressed Hydrogen provides significantly better energy density but less power density. Power density is largely due to the size of the Fuel Cell (PEM-Stack). Can't just make the fuel cell larger as it quickly gets heavy. They can get around this the way they do for HFC automobiles by using a battery as a buffer but this also adds weight. For larger aircraft HFC technology begins to make more sense.

If it's in the air for 3 hours and the solar cells themselves have weight and added complexity/cost, it may not be worth it. If the solar cells can charge the battery 5% in 3 hours but the extra weight reduces range by 10% and add 10% cost, then it's not a good trade (example numbers only, no idea on the true numbers).
