I'd like to see this for a used aircraft, too. When I'm on the leasing screen, if I reconfigure the plane, the range changes. But I'm only guessing by how much. As soon as I order the plane, I get a definitive answer, as it's listed under 'aircraft on order'. The nominal range appears on the aircraft info screen, but when you move to the leasing screen, it isn't there. It would be great to see on the configure aircraft tab, along with the new seating arrangement and the cost, the new nominal range. Makes a difference when you're flying routes right at the range limit. If it appeared on that tab along with the cost, you'd be able to see it whether congfiguring an already owned plane, a used plane you're about to get, or a new plane you're about to order too.
