my tailwind requires 74hp to cruise at 120 knots.
it takes me two days to fly across australia.
Of course, the typical light airplane flight probably does not even involve X-country flight. A 2-hour electric airplane would be just fine for the typical 1 to 1.5 hour training mission. Of course, that same plane would need to be ready to fly the next training student/renter within 20 or 30 minutes. Given what we know about today's battery technology, time required for recharging may be a big problem.

Fortunately, in that service multiple battery packs could be used to
overcome down time due to recharging.

Yeah, right.

The typical car battery pack costs about $3k to $5k, do you think an
airplane battery pack will be cheaper?

How many battery packs do you think the typical FBO is going to be able
to buy?

The best of batteries only last about 5 years, so every 5 years or
so the FBO has to replace all those batteries.

Real economic winner there.




Actually, the cost of replacing the battery packs (after five years) will run around $5000.00. That's $1000.00 a year plus the cost for multiple recharges @$.60 per charge... If you put 100 hours on the old "Hobbs" every year that's the equivalent of paying about $10.30 an hour for fuel... What's a gallon of 100/130 down your way?? Then there's the savings on maintenance... The prop is a composite material with no time life. The "engine" (electric motor) doesn't have a TBO rating. When you factor all the costs of operating a typical two place single (like a Cessna 152), a $5000.00 battery pack is "peanuts". What's more, if you put more time on the machine and use a trickle charger which won't stress the battery, your operating cost will only increase by the number of charges (@ $.60 per)... So let's say you "double" the number of hours in the air... The "fuel" cost factored over 200 hours now drops to $5.30 an hour. Yikes!!! :-)
