Last night listening to Chicago approach on the internet I hear Am Tran *** heavy. I thought wow a L-1011 to MDW. I look it up on a flight tracker and it was a B753 LAS-MDW. I thought a HEAVY was a twin aisle jet.
What then is it?

It has to do with weight. It does not have to do with the number of aisles. All twin aisle aircrafts meet the weight requirement so all twin aisles are heavy.

Please correct me if I am wrong.

It can be confusing regarding what a heavy is. Generally, i think of a "heavy" as a twin aisle widebody plane. Anything from a 762 to a 744. I wouldn't consider a 757 heavy though.

The definition for a heavy (here in the US) used to be 300,000 lbs, but it was changed to about 255,000 (can't recall the exact figure). You might do a search of the messages, as I'm sure links to the official criteria have been mentioned before.

Even though some 757s are below the 255,000, they are still treated as heavies for wake turbulence separation...

Heavy is added as a designation to warn others that the aircraft is capable of producing moderate to severe wake turbulance. The B757 was added some time ago because of the wake turbulance encountered by following aircraft.

The B757 is considered "heavy" due to the important wake turbulence it makes !!!
