Anyone enlighten me why some aircraft call signs are followed by the word HEAVY?
I am assuming they are fully loaded with PAX and cargo, but most international flights are already fully booked, so what does HEAVY specifically relate to?

Re: Qantas 56 HEAVY
The flight number is used as reference, preceeded by what is called the airline's callsign, and followed by the word "Heavy" if it is an aircraft capable of generating a large amount of wake turbulence (see the glossary). Once the identification is done, after a couple of transmissions, the word "Heavy" can be left out, and for expedited communications.

So basicly any wide bodied aircraft thats over a certain weight, they would say their callsign followed by "Heavy" so others in the area can adjust and recalculate for the amount of turbulance etc

Re: Qantas 56 HEAVY
The true clasification is based soley on the GW of the aircraft - hence - some times 767 can be "Heavy" and then other times - they stay in the medium cat. Same with the 330 and a few other aircraft.
With different clasifications - there are different seperation standards that need to be applied to other aircraft to avoid wake turbulance - for all phases of flight - t/o - climb/crz/des and landing

Heavy- An aircraft with a AUW above 300,000 pounds.
AUW - All UP weight, which is the total aircraft weight.
