A Kingair is a A,B,C,E (etc) 90 or 100. (but not a Beech 99....)
A Super Kingair is a Kingair 200, B200, B200C, B300.
Similar but quite different aircraft. I know several people who use the different terms 'on air' because they are or were rated on the different aircraft; not because they are w@nkers.
Cleared that up?
