I would expect the problem to be "mass goes up with size cubed, while parachute drag only goes up with size squared". I.e. you need a disproportionately larger

I would expect the problem to be "mass goes up with size cubed, while parachute drag only goes up with size squared". I.e. you need a disproportionately larger chute (or more of them) for large aircraft. Those are dead weight in normal operation, which really hurts the economics.
