I was just wondering, which aircraft have the heavy rating? Also what exactly does that mean for the aircraft procedures itself? I know u have to say the word heavy in the transmission, example. "DELTA 155 HEAVY, POSITION AND HOLD RUNWAY 24 LEFT" I believe the following aircraft have the heavy rating. Correct me if im wrong please!
So can someone explain what a heavy rating does for a aircraft and its procedures with the Air Traffic Control Tower and the Captain and First officer operating it? Special procedures? Thanking you in advance!

It's assigned to any aircraft with a gross take-off weight of 255,000lbs or more. It basically applies for any aircraft that will cause significant wake turbulence. Basically, anything from a Boeing 757 up...

Not to nitpick, but even if it's a 757-200, it get spaced like a heavy and we small guys in RJs are warned of their wake turbulence. Also, some -200s have a higher gross weight than 255,000 that puts them in the heavy category.
As stated, there's a greater distance of spacing between heavy aircraft and large or light aircraft. I think it's five miles, but one of the resident controllers will have to chime in.

Not to nitpick, but if it's a 757-200 it gets spaced like a 757. This means it's considered large when it's the trailing aircraft, and a 757 when it's the leading aircraft (more separation than a large, not as much as a heavy).

I couldn't find anything in 7110 that stated anything other than spacing behind a heavy/B757.
After seeing what could happen to something that weighs 100k more than a 75 (like an A-300 does) behind a 747 I think I'd like a little more distance.

It doesn't apply to your actual take off weight but the maximum certified take off weight of the aircraft, irrespective of the weight of the day (or maybe that's what you meant by gross?).

When I was studying for my Airport Vehicle Operators Licence and my Radio licence, I remember the book saying that on the radio "Heavy" is added to the callsign of any aircraft over 300,000lbs.

It's in 5-5-4-e through 5-5-4-f:
WAKE TURBULENCE APPLICATION
e. Separate aircraft operating directly behind, or directly behind and less than 1,000 feet below, or following an aircraft conducting an instrument approach by:
NOTE-
Consider parallel runways less than 2,500 feet apart as a single runway because of the possible effects of wake turbulence.
1. Heavy behind heavy- 4 miles.
2. Large/heavy behind B757- 4 miles.
3. Small behind B757- 5 miles.
4. Small/large behind heavy - 5 miles.
WAKE TURBULENCE APPLICATION
f. TERMINAL. In addition to subpara e, separate an aircraft landing behind another aircraft on the same runway, or one making a touch-and-go, stop-and-go, or low approach by ensuring the following minima will exist at the time the preceding aircraft is over the landing threshold:
NOTE-
Consider parallel runways less than 2,500 feet apart as a single runway because of the possible effects of wake turbulence.
1. Small behind large- 4 miles.
2. Small behind B757- 5 miles.
3. Small behind heavy- 6 miles.
So a large (like a 737) only gets 4 miles behind a 757, but 5 miles behind a heavy. A heavy behind a large would get 3 miles, but a heavy behind a 757 gets 4 miles.

I imagine the reasons for the increased separation between small aircraft and the 757 have been discussed before, but how about a quick refresher from someone.
I remember reading quite a lot about it when the phenomenon was first recognized. All I remember is that the 757 possesses some aerodynamic peculiarities that result in an exaggerated wake.

Your book is old...it used to be 300K, but was reduced to 255K a few years ago.

Pip,
There are some times where we differentiate between a 757 or a Heavy.
Anywho on the whole 752/753 thing, the FAA's stance regarding the issue is that a B753 is a "Heavy" and will be marked H/B753 and a 757-200 is in its own class regarding wake turbulence applications. (Would be marked B752).
The weight categories are also a little misleading. The Saab 340 is considered a "Large" aircraft though its MGTOW is not more than 44,000lbs.
Keep the blue side up and green between!

Quoting Pilotpip (Reply 16): So when I'm in my ERJ and trailing a 75, do you guys give me the same space that you would if I were following a 747?
Sort of. An ERJ (Large) behind a 757 (200) requires 4 miles seperation when the preceeding aircraft (the 75) crosses the runway threshold. So what we do is judge the speeds etc to make sure we never go below 4 miles seperation, and when that 75 is just over the runway, Bam! you hit exaclty 4 miles. Takes lots of practice. (Im horrible at it, but im not an approach controller).
Now say you are in trail behind a 767 or some other heavy (74 in yoru case), then everything is the same except we need 5 miles.
Have a gooden!

Thanks for the info! I'll probably be the one you are yelling at to keep my speed up for the next couple months depending on where you work.

Well considering our youngest airplane is a 737-200 from 1980, the majority of our fleet is HS748s, and most of our ground equipment could pass as "classic", I wouldn't be surprised at all if it was an old book.
Thanks though, I'll start remembering it as 255 now.

Will you be IOEing? If so, good luck.
It is a mistake to think you can solve any major problems with just potatoes.

Not to nitpick... but if you are going to add a snide comment to a conversation, its always best to make sure you convert the right numbers... 136000kgs is 300,000lbs, not 255,000.
