All aerodynamics are now done with computer simulators. Once the design is narrowed, wind tunnel tests are done to confirm the computer data.    The easiest way to experiment with airfoils is to use one

2016-08-15 International airport design.:

There is no clear answer. It really depends on the space available and the foresight of the designers. I would say (generally) that most airports are designed to include terminal expansion up to 20yrs
