If it were possible to build and run a chromodynamic model of the 747, it would yield accurate predictions. Better predictions than the aerodynamic model, in fact.
This is not very important, but I think this is not quite right in general. Assuming that we’re making some modelling assumptions about the plane and the air and so (rather than, for example, running a whole Universe sim) I think it’s possible for the errors of the non-QCD model to systematically cancel out the errors of the modelling assumptions and end up more accurate than the QCD model.
