Would someone clarify what is being meant by "starting" a default aircraft in this context?; does it mean setting an original aircraft as the default, opening the preview screen, then changing to a different model? or does it mean selecting the designated default aircraft and changing after loading it to the takeoff location?
Also, in context it seems the term "default" is often used to describe one of the original aircraft aircraft that was delivered with the FSX installation, and not an add on. This would be different that referring to the aircraft designated from the installed fleet and designated as the "default." I could designate any add-on aircraft as the default.
