I thought about doing that, but there's so much personal info attached to a N#, and tracking info that I try to limit its exposure as much as possible.
Loophole. Takeoff across the runway. Then wheel speed can happily match treadmill speed up to takeoff. Just have one hell of a crosswind until you get off the ground.
Nope. You have to haul around the cooling drag for an entire 300hp engine. plus a windmilling prop, plus 3x the weight, plus the sonex was engineered to have a turbine engine and will be more efficient. Your assumptions are flawed.
Look at the thrust on that. Ain't gonna cut it for a 3000+lb airplane.
Go try to fly your plane at 35% power. Hint (Economy cruise is your most efficient, any deviations from that and you get less efficient)
And then immediately after that sign up for physics 101.
Let's say you need 50% of the power to keep the plane aloft. A lance is what 300hp? So let's call it 150hp = 112kW. For 10 minutes that's 19kwH with 100% efficiency. Driving an engine and prop with a mechanical system is probably closer to 50% efficient (if that), so you're talking 40kwh battery...
It doesn't happen very often, but there are usually stipulations in the Lease to allow the airport to terminate it given a set of circumstances. It could be as simple as the airport is redeveloping the apron and your hangar is in the way.
