Heavy means that is a very large airplane. A heavy airplane weight more that
255,00 pounds.

Let me put a little background behind that.

Air Traffic Control is responsible for keeping a certain amount of space
between each aircraft. The exact amount of space varies with a bunch of
different factors, but it's typically several miles.

Airplanes create an invisible wake in the atmosphere, just like a boat
creates a wake on the water. And, just like the boat's wake, the
airplane's wake can be dangerous to other airplanes. Heavy airplanes
create bigger wakes, so ATC is required to give an airplane following a
Heavy some extra distance. ATC is supposed to know if a given type of
aircraft is considered Heavy, but as an extra reminder to controllers,
pilots of Heavy aircraft add the word "Heavy" to each transmission.
