Pilot here, I don’t think this is right.

Aircraft typically operate at 80-100% power output. It’s not the average 20% power output of your car.

Weight is pretty much everything, the savings from regenerative braking in an aircraft are almost 0% but the cost of enabling it is some tons.

This tech makes loads of sense in a car but I’ve never flown an aeroplane in stop-start traffic because that’s not how the sky works.
