Engine/motor

Talk about airplanes! At last count, there are 39 (and growing) FAA certificated S-LSA (special light sport aircraft). These are factory-built ready to fly airplanes. If you can't afford a factory-built LSA, consider buying an E-LSA kit (experimental LSA - up to 99% complete).

Don't get me wrong. I think electric powered LSA will/would be great when/if they get the range, endurance, and useful load to an acceptable level for the average aircraft buyer, not just flight schools. One hour of flight time is totally unacceptable for most people, I suspect. And, I don't accept that the FAA is the limiting factor.

Did you just contradicted you own argument? People who try them love electric vehicles. I have an electric car, a Bolt, and never want to go back to gasoline. There are just too many benefits to the electric. Does if fit all my needs? No, but it fits 90% of them far far better than a gas guzzler and I can rent (and have) for long trips and still come out ahead. I predict this is where flight training will go with electric. Pattern work and short lessons in electric because it's WAY cheaper and longer flights in a conventionally powered plane. I think the economics will force this to happen at some point a few years down the road. The cost of the battery is pretty prohibited in a car, but is comparable to an aircraft engine and should have a much longer life between overhaul/replacement. The electric motor is essentially maintenance free. The wear and tear on the airframe is a lot less because there is little to no vibration. The cost of fuel for a 1 hour flight should be around one dollar.

At any rate it will be interesting to watch evolve.

No, I didn't. How many Bolts do we see driving around? How many people want to rent a car every time they want to go somewhere? Again, the current electric technology may be marginally acceptable for a flight school who wants to train in 1 hour increments, but that's it. To be commercially successful for most pilots, electric airplanes are going to need to get quite a bit better in terms of range, endurance, and useful load with larger/more batteries. How can anyone argue that is not the case? It's wishful thinking that may happen some day. Maybe not.

My point is, the FAA is not the problem. The current state of the technology is the problem.

I agree that the technology has a ways to go to make electric aircraft acceptable to a large majority, but the current rule is stopping what is currently available from being used. If the rules won't let you use the marginally acceptable aircraft that are already available, why bother developing anything else?

Regulations that restrict the use of something does not provide a healthy atmosphere for development of anything

I don't see why there is a problem with using any type of power plants, if that would have been the case in the automotive world we would be driving around in steem powered cars because the DMV said no you can't have any other engines or be diverse

I feel confident that when there is a viable electric option, it will be approved. There is no reason it wouldn't.

I'm sure this is just another example of the Law of Unintended Consequences. The FAA meant "no jets," but they worded it "a single reciprocating engine." Since there were really no electrics 15 years ago when the rules were being written, the wording was adequate. It no longer is.

Problem is, it will take another 15 years to do a petition, an NRPM, public comment period, publication of comments, solicitation of responses to the comments, publication of those responses, revision of the NPRM, a comment period on the revised NPRM, replies to the comments on the amendment, etc. ad nauseum.

No, I'm not a crook or traitor. But, I will be switching from AT&T U-Verse to Charter Spectrum.
