As an FYI, there are precise definitions available from the US Dept. of Labor detailing exactly what differentiates one level of skill versus another in any kind of professional job. It's not a matter of debate as far as they are concerned, they use phrases like "makes decisions using prior education or training equaling or exceeding x years, with OTJ oversight by superiors in making those decisions less than x% of the time"-ie. very detailed. Right off hand I can't recall what they say about pilots.
