Hi all, could someone tell me if the term 'heavy' relates only to the '747 queen of the skies' or also to other types, such as the 737, etc.Also, is there a definitive list of abbreviations used in the aeronautical world available to us newbies, on a particular website.Thanks.Keith Sandford

The term heavy relates to aircraft over a certain weight...Heavy- Aircraft capable of takeoff weights of more than 255,000lbs (115,770.00 kg)whether or not they are operating at this weight during a particular phase of flight.
