Good info. One correction though. The term "heavy" has nothing to do with
load. It's size. Full size commercial jets such as 747, 757, 737, ect. are
"heavies".

A "heavy" usually means a
heavily loaded plane, full of people, full of fuel. IE: a fat loaded
747 might ID as United 247 "heavy" as an example.
