Range would be around 30 miles powered? It is slow it cruises more like 40/46 than 55/61 and about 40 minutes of battery.
Unless the wind is not blowing and/or it's night time.Yes but if you have your own wind turbine or solar cell system, you fly almost free.
Unless the wind is not blowing and/or it's night time.
Gas pumps work in a dead calm at night.
And you have to factor the costs of your own wind or solar system into the cost of ownership of the airplane.
And if ti's a wind turbine you have to factor in the hundreds of thousands in cost of decommissioning the turbine:
"Decommissioning the Palmer's Creek Wind facility in Chippewa County, Minnesota, is estimated to cost $7,385,822 for decommissioning the 18 wind turbines operating at that site, for a cost of $410,000 per turbine."
I haven't done the calculation but I suspect that the cost of a personal wind turbine system or solar cell system that can recharge an electric airplane in a reasonable amount of time (15 minutes) would be highly prohibitive. Not to mention how the neighbors would find it.
Or do you imagine that the airport woudl allow you to install a wind turbine next to the hangar in which your plane is stored?
If you have a battery bank, charged from your own wind or solar system, from which you charge the airplane, then you are supporting the costs of 2 battery banks.
I say "personal" system because you used the phrase "your own" in your statement.
Yes very few have personal/own wind turbines. It would be possible though.
Lots of things are "possible". It's possible that I might build a hangar at my local airport. But extremely unlikely. So certainly not worth planning my future on.
Giant wind turbines in every pilot's back yard is "possible" but so unlikely that it's not worth speculating on electric airplane futures based on that.
It does if you wish to compare operation convenience with ICE engines. Takes me about 15 to refuel my plane but I'm pretty leisurely about it unless there's a line waiting.Does it need to? I’m too casual to do a fifteen minute turn. An hour would be fine by me.
A friend of mine who’s big into EVs would probably argue that it takes fifteen seconds to plug in and walk away. In that way it may be more convenient than an ICE. I don’t know what’s required as far as infrastructure installation and upkeep cost goes to charge an airplane but perhaps an electrified future would have a row of 5-10 places to charge versus the current 1-2 gas pumps.It does if you wish to compare operation convenience with ICE engines.

I agree, two hours is too much. One hour is probably acceptable for an awful lot of single-engine light GA, even if the current users don’t recognize it.If people have to wait 2 hours to recharge then the e-planes lost a huge part of the possible customer base.
You're right. 50% efficiency at max power is a theoretical number, never achieved in practice, but good motors are very close to it. Anyway it's a moot point since no motors can operate at that loading.
I can vouch for that. The convenience of charging at home means for me not freezing at -25C plus windchill for 10 minutes at the pump.A friend of mine who’s big into EVs would probably argue that it takes fifteen seconds to plug in and walk away. In that way it may be more convenient than an ICE.
that depends on your religious beliefs, which is a discouraged topic for discussion here.How far away from sound, (and practical) are these green tech systems,
This recharging has to be designed thoroughly. I bet a system where the stardard batteries are switched in 10 minutes is very doable. Possibly date on the batteries would matter in the charging of the charge...newer batteries would be less costly when charging and vice versa ( you could possibly get charge for free if you have to switch to older ). All batteries would be dumbed after certain amount of charges.Ok and can that recharge an electric airplane with substantial range (say 4 hours flight time) in 15 minutes?
Honestly... I don´t expect that we can expect "standard charging stations" of airfieds in near future.Yes, you'd need multiple smaller batteries if swapping is going to work. Developing some sort of standard for size and compatibility, like standards for USB connections, would also be required. Don't want to arrive at an airport and find they only have Beta when your aircraft uses VHS. The weight and hazard issues will likely reduce as time passes. And let's face it, this isn't something that would happen overnight. Just developing a standard would take years of government bureaucratic nightmares. By that time, swapping may not even be necessary.
