How heavy does an aircraft have to be before it is a ‘‘heavy’’ aircraft?
300,000 pounds. There are, however, exceptions for aircraft weighing less than 300,000. I’ll see if you are good enough to use Google to find these exceptions. Report back within 24 hours. This will go on your permanent record.
GOOGLE IS YOUR FRIEND!!!
I hate reading, easy to ask someone if they know. 
255,000 lbs?
easy = lazy
Kids these days…what are you gonna do. 
You think I don’t know that.
I’m better at using my back, not my brain… Reading just is not my God-given gift.
You don’t know what you are missing. There’s a world of wonder to be discovered if you read.
Read to learn. You can learn more things by researching and finding out for yourself then you ever will by having others give you the answers.
Read to escape. There’s a fiction book out there for every taste: mysteries, thrillers, science fiction, humor, etc., etc.
Read to be romantic: The women folk love it when you read poetry to them
I’m convinced that people can do what they want to do. Using the excuse “I’m better with my back than my brain” doesn’t cut it for me. Everybody can read - even the blind.
Reading and working with your back are not mutually exclusive. Several good friends of mine are in the construction industry. They read just as much as, if not more, than I do.
I know how to read, but I only read if i need to, mainly for school. But lately I have been making myself read some. I am reading a Smithsonian aircraft book and I read alot on wiki about airplanes, and this forum. I know I am going to read and study alot when I get older because I hope to join the Air Force and fly a C-17… anyhoo. Is 255,000 lbs correct for heavy aircraft?

Damiross is gonna get angry at you little fella.
Congratulations, will744. 255,000 is correct. (300,000 is what it used to be).
If you are planning on going into the Air Force, you might want to do a Google search for Air Force Publications Library. You’ll be able to download lots of technical publications regarding the C-17 and other aircraft there.
Thank you very much. I am trying to learning everything I can right now so it will be no problem when I get in the Air Force.(there still will be plenty of problems though I know)
Didn’t sound mad to Me, ha!
I was wondering if the weight had changed…
I was listening to KSAN tower the other day, and noticed an AAL B752 being referred to as “heavy.” But it was just a B752 with winglets…as I don’t think AAL has any B753’s.
There’s a 127.5t MGTOW option for the B752, bumping them into the heavy category.
Correct me if I’m wrong here 
BUT doesn’t the thrust have something to do with the “Heavy” in a callsign? Go ahead flame away 
Don’t know about thrust. I do seem to recall that the 757, even under 300,000 pounds, has been considered a “heavy” for many years due to the way it messes up the air behind it (i.e. the turbulence it causes).
The 757 gets the Heavy addition to their call signs because of their Wake Turbulence Separation Minima for ATC. They may not follow the rule for maximum takeoff weight, but the FAA had to amend wake turbulence rules and the separation standards for 757’s after accidents like this one:
articles.latimes.com/1994-07-09/ … turbulence
So, the FAA added the 757 to all paragraphs that told controllers the phraseology and spacing rules for wake turbulence.
So, the 757 isn’t a “heavy aircraft”. But it is a “Heavy” for wake turbulence rules.
That should read " the 757 isn’t necessarily always a “heavy aircraft”…
