I know I am probably too late but here's a list of simple "yes-no" questions that a visitor to the show should ask the people at the booths, *if* those people have some actual access to real info.
Does HQA have the same range as FT-2000?
Does HQB have greater range than HQA?
Does the J11B use WS10 variant named WS10B?
Does J16 use the same variant?
Does WS10B have at least 130 kn of thrust?
Does Y20 with the current Russian engine have may payload of over 60 tons?
Is width of the cabin floor on Y20 at least 4 meters? (this really they could give out the accurate figure on as well, as Y20 is probably going to be offered for export as soon as the domestic engine becomes available)
