I have an idea. Just switch the engines off when the plane is coasting. Works for cars at stoplights [almost totaled a rental car in anger at discovering this “feature” which shut the engine off just before the light turned green. Do you know what happens when you floor an engine that is off and trying to start. Car stopped in the middle of the intersection.
I was just looking at some new vehicle specs and it looks like just about all the new stuff has the NON optional shut on/off “feature”. Some seem to have a disable mode but you have to select every time you start back up. Oh well.
