Heavy 757?

Wed Jul 28, 2004 5:38 am

I was listening to Norcal approach yesterday and I realized that the Northwest 757-300 pilot noted that he was heavy. Apparently the controller seemed confused since at times he forgot to say heavy after the NW's callsign. Prior to this, I thought that usually only widebodies use heavy. Can anyone shed some light on this?

Thanks

The 757 is unique in that it is the only narrowbody aircraft to earn a "heavy" on its callsign. This is a result of its ability to create strong wake turbulence that is more powerful than other narrowbody aircraft.

Try doing a search, as more has been said about this topic before, and it is quite interesting. Cheers!

Concorde was also a narrowbody that attracted 'heavy' in its callsign.

There was a discussion a few days ago which mentioned that "heavy" is used for an aircraft that is over a certain weight, and 757s can be both heavies and non-heavies.

As stated years back the weight limit for the heavy designation was lowered to 255,000lbs specifically because of the severe wake turbulence the 757 produced. I havent ever heard of ATC using the term "heavy" in the callsign of a 757 as that term is still mainly used for the true widebodies. However controllers will usually always say "caution wake turbulence following a Boeing 757". Although im not positive the DC-8 and 707 were likely heavies even though they are single aisle narrowbodies.

You guys raise good points. First of all, I didn't know the Concorde could also be referred to as a "heavy", but that would make sense, with the drag produced by the delta wing. Secondly, it would make sense that a DC-8 or 707 would produce at least as much wake turbulence as a 757. Perhaps I'm the one who should do the search for the older topics to learn a bit more about this  Big grin

Generally you only hear 757-300's being called heavy.

I thought stretched variants of the DC-8 such as the 60 and 70 series called "heavy".

I remember hearing ATC in SJU call UPS's Stretched DC-8s "Heavy" when talking to them.

Any aircraft CAPABLE of a takeoff weight of 255,000 lbs or more, is classified as "heavy". This applies to some, not all, B757-200s, and to all B757-300s. B707-320s, and 420s are Heavies. Some, not all, DC-8s are Heavies. The KC-135s that are reengined with CFM-56 engines are "heavies".

The requirement is based on what takeoff weight the aircraft is capable of.

I don't understand everything I don't know about this.

Don't forget the DC-8 stretch and the 707s! UPS DC-8s, for example, are well over 255,000 lbs so they are heavy. Also, the 757-300s (and ATAs 757-200s) are over 255,000 and also have high-lift wings. Thus, heavy.
