What is a commercial airplane?

Answer:
A commercial airplane is an airplane that is being used in commercial service--where people are paying for the plane to be flown. ANY plane can be a commercial airplane; if you've got a business picking up X-rays from small airports then flying them to Rochester International Airport in Minnesota so a doctor from the Mayo Clinic can review them, and you use the cheapest Cessna you can get your hands on to do it, that Cessna is a commercial airplane. Having said that, usually "commercial airplane" means one that's large enough to carry many passengers or a lot of cargo.
