do 757s use heavy in their call sign?

[devitomd]

Some of the 757s I download have atc_heavy enabled and others don't. Which one is the right way?

757's do not use heavy in their call signs

... but they are very close to it. From what I know, any aircraft bigger than a 757 is "heavy". Might be the reason why some downloaded 757s have it.

I thought it was to do with the weight of the aircraft.
i.e you get a 747 and a 747 heavy, but they are both 747's.
I've never known why or when an aircraft is assigned as "heavy"

Most 757s do indeed use the "heavy" designation. Most of the Delta and Northwest 757s that come into Tampa use it in their callsign.

The "heavy" is used primarily to signify weight, although I've also heard that the 57s use it because of the wake turbulence they create.

Either/or... I hear it a lot.

Actually, the B757 can be both heavy or non-heavy depending on the specific aircraft. The heavy designation (for wake turbulence purposes) applies to aircraft that are capable of a maximum weight in excess of 255,000 pounds. At my airline the B757-200's have a MTOW of 255,000 pounds thereby making them just barely a "non-heavy". The B757-300's have a MTOW of 260,000 pounds, thereby classifying it as a "heavy". Please keep in mind these numbers will likely vary carrier to carrier.

ATC is supposed to give heavies a greater lead because they create more wake turbulence.

In the approach configuration, the 757 has an extraordinarily turbulent wake for its actual weight. This was not discovered until at least two bizjets were lost in the wakes of arriving 757s.
