Also, many don't know or care, but you only use "heavy" in the call sign on tower and approach, not center.
CAL 757-200's are 255,000lbs, but do not use "heavy"? Different airlines have different weights/models. The 757-300's are heavy.
I do believe an aircraft is a heavy if it is greater than 255,000 lbs MGTOW but since the 757-200 is exactly 255,000 lbs it is not a heavy. Go Figure.

The 757-300 is 272,500 lbs so it does qualify.
