Tied Down
Prototype flew.
I don’t think electric aircraft are as affected by density altitude. You don’t lose any engine power.
The air is still thinner at higher density altitude, so aerodynamic issues still change. The wing and propeller still encounter fewer air molecules with which to interact.

Of course, but it will be putting out full rated HP unlike normally aspirated aircraft. Basically it’s like having a turbocharged airplane which is much preferred.
You don't hot dog a plane on it's first flight. It's not conducive to becoming an "old" pilot.
Nick Otterback builds great airplanes. I've flown the LS-1 Lightning, and I'd own one in a heartbeat.
Electric airplanes and hybrids are on the way not practical for cross country,but should fit into the training market,initially.
If Tesla starts making airplanes, I'm in!! Can you imagine ludicrous mode in a plane?!The electric airplane may prove to be just as popular as the electric car....

I saw a presentation by SunFlyer a number of years ago, and they were upfront in saying their initial market was training, since the range of the airplanes was limited.Electric airplanes and hybrids are on the way not practical for cross country,but should fit into the training market,initially.

I wonder how many training flights can be flown in a day.
Yes, but did it land?
They say that charging should take 20 to 30 minutes, so probably quite a few.I wonder how many training flights can be flown in a day.
That was back in 2016.Recharging time for the airplane’s lithium-ion battery pack after a typical sortie should be 20 to 30 minutes using “supercharging” technology.
The other side of this whole "electric car" movement is that the electric grid is not up to the task of having every single home charging one to two electric vehicles in their garage every night, not to mention apartment complexes full of charging vehicles. There will be a pain point in there somewhere without significant infrastructure upgrades.
“Say fuel and souls on board...”
Zero fuel...
That could be quite a safety advantage... Though damage to batteries can also be dangerous, it doesn't result in the instant fireball that a gas tank breach can. While Lithium is nasty stuff and the fires do result in being very hot, they generally happen fast enough for occupants to exit safely, and they don't happen nearly as often as gasoline fires in cars either.
The danger probably lies more on the crash rescue team than the occupants. Energized airframe components while you’re trying to dig injured people out of the crumpled metal. Of course, most of these are composite structures now, so that helps.

This represents a "training opportunity" for local first responders, like Cirrus does with the chute rocket setup. Most electric cars have a disconnect and/or a spot that you can cut so as to disconnect the battery. The disconnects also generally "split" the battery into multiple "pieces" such that the voltages aren't high enough to cause harm to humans any more.
Think of it like main and aux fuel tanks, except they're all the same size. While most electric car batteries are in the 400V range, if you run it as 8 separate 50V batteries, a single one isn't particularly dangerous. Run the wires all up to a disconnect in front of the firewall before you combine the voltages (series) and once you pull that disconnect, there's no more dangerous voltage.
It's my understanding that the grid is under greatest load in the middle of a workday when air conditioners are running at peak. Since generators have to run 24/7 and there's little load on them at night, the power company charges less and why it's better/cheaper to charge overnight.I've always thought that it's silly that we all charge electric cars at home. Ideally, electric cars should be charged wherever they sit for long periods during the day, so that they can use energy from local solar rather than taxing the distribution grid. In fact, if there were solar-only charging stations wired to provide the right DC voltage, maybe we could get away without pushing the juice through an inverter and then rectifying it back to DC and the inefficiencies inherent in those processes.

Maybe this is only in Los Angeles. If we built out more solar charging infrastructure this might change.
Here we go again. Electric planes make no sense. Totally impractical.
