I used to work for XLA and we flew the 767 which were still on the Icelandic register then, and we used the "heavy" designator on a number of flights, but im sure someone told me it wasn't simply an a/c type thing, it was down to gross weight on the day and some a/c types such as the B727 have used it, due to them being heavy that day, to let the ATC controller know that they were heavier than normal for seperation purposes.Not sure if thats true ot not though.

Heavy is a purely US terminology. Not sure about Canada.
Incorrect. Although there are some differences between US and European (for example) terminology, like Capt.Fantastic pointed out, heavy is a standard term, certainly used throughout the US and Europe. It's FAA (US) and JAA (European) regulation to use heavy in the call sign of an aircraft in the heavy category, at least on first contact with the particular ATC unit being contacted.

I can't address international airspace, however in US airspace the controller is required to use the term "heavy" in radio conversations in the terminal airspace, but not en route airspace, with the exception of issuing traffic to another aircraft on a heavy.
( From the controllers handbook) Heavies are aircraft capable of takeoff weights more than 255,000 pounds whether or not they are operating at this weight during a particular phase of flight.
B757-300, B767, B747, B777,DC-10, MD-11,Some DC-8s, Some B707s, A300,330,340, L-1011, C5, C141,C17,B-52, Some KC-135s, VC-10, IL-96.....a few others.
I don't understand everything I don't know about this.

I believe use of the word "Heavy" also has to do with the flight performance of the aircraft, and that is why the term is most applicable to terminal areas. Some heavy aircraft may have problems staying below the terminal area airspeed limits and the 250 knot rule below 10,000 feet, eg the Concorde.
So for flight safety and performance, heavies may fly faster.
For example, a T-38, due to its performance characteristics, has an FAA exemption that allows it fly at 300 knots when other aircraft are restricted to 250 knots. You wouldn't think of a 12,500 lb two seat trainer as a heavy, but it is basically the same principle.
I'm just happy that RR ratings can't be in negative numbers!

According to JAR, an a/c in the wake turbulence category "heavy" should on initial contact with an ATC unit include the word "heavy" immidiately after its callsign.
An a/c is included in wake turbulence category "heavy" when its MTOW is 136,000 kg or more.

Many come here to learn, If we all knew the answers there would be no point in having the forums, except maybe for those who want to yell "MORON" and not be gracious. Someday they will learn, it takes too much effort to be an asshole.

You will hear ATA, NW, CO and Condor use the heavy designation for their 753's since Boeing did extend the fuselage. Therefore, increasing the weight above 255,000. The 752 on the other hand (correct me if i'm wrong) weighs 240,000lbs. I have never ever heard a 752 called a "heavy" simply because of the letters showing its a 752 and of the wake turbulance "H/L/B752" (I can't remember). You will also always hear an ATC let an a/c on final or taking the active of a 75 in the vicinity and "Caution wake turbulance"

Correct on the 753/752 thing.
I often spot at MSP with the scanner in hand.
753's are called as heavies.
752's are not called as heavies.
ATC does call wake on all 753's and 752's if an aircraft is landing/departing within a 5
mile gap of the 757.

Regarding the 757, only the -300's are designated "heavy."
How wrong you are... When I lived in Maryland two years ago, I used to visit DCA all the time. The 757-200's from MDW used "Heavy" in the callsign. NAS North Island had an ATA 757-200 a few weeks ago... "Heavy" was used.

The book may say one thing, but the only time we've ever had to use the term 'heavy' is for the North American ports, where it is applied religiously for every transmission. Not enroute over Europe for the most part except for the U.K. (where you will probably only hear it entering the FIR or terminal area), and certainly not in Hong Kong.
On my last flight into Vancouver, the ATC did a traffic report for a Cheyenne flying towards enroute Tofino. "Your traffic is at your 12, an Airbus 340 heavy." That was fun.

With us in Maastricht airspace we as air traffic controllers don't use the term "heavy". But quite often pilots coming back from the States use it in addition to their callsign, I think it's just a habit they keep during the whole flight. So it can be heard every day in European airspace.
