"Heavy-Heavy" Callsign For The A380?

Sun May 28, 2006 6:31 am

Since the beginning of commercial operations of the A380, hopefully late this year, which in my understanding will need an even more wider separation from other aircraft, what would be your message to ATC -- "heavy," or "super heavy," or something like that, that would identify your aircraft.

"Heavy-Heavy" Callsign For The A380?

Sun May 28, 2006 6:47 am

I don't think there will be any special callsign for the A380.

Honestly, It puzzles me how 'freaked out' people seem at the size and weight of the A380...as if it's bigger than anything that's graced the skies...when clearly it's not.

It's in the same league as the 747, C-5 Galaxy, An-124, and An-225.

Do any of those aircraft get special weight designations? No.

So why should the A380?

My guess is separation for the A380 won't be terribly greater than any other such loaded aircraft in the pattern.

We really aren't going to know until they actually take to the skies, but I don't think the A380 is going to see as many special considerations compared to the 744 as we think.
I'd take the awe of understanding over the awe of ignorance any day.

People made a big deal about it because Airbus stated that the A380 would have the same separation as the 747. It was just another reason for A bashers to jump on the A380 and say "A-ha, I knew that plane sucked!"

But really the separation info came at point when Airbus was struggling with PR in general (the A350 in particular). The one bright spot for Airbus at the time was the A380. It was a chance to drag that program down too. Airbus said the initial separation would be decreased. Time will tell. I hope for Airbus sake that it is. If not, their reputation for missing promises will continue.

The A380 isn't the biggest jet out there. The Antonovs are still bigger, as is the C-5... why would the A380 be special? A heavy is a heavy is a heavy. Sure, it may require more seperation than a 747, but so do the big Antonovs. No big deal.

I think it will be handled like the 757 (excluding those actually heavy enough to carry a "Heavy" callsign) and the callsign will still be heavy, but the controller will know from the flightplan that it is an A380 so they can apply any special spacing.

The term heavy doesn't mean that the plane has to be heavy. It's just added to the ATC ID to recognize the plane as one which produces heavy turbulences behind and other, especially smaller planes, have to keep a big distance to avoid problems. That's why the not so heavy 757 is called heavy on ATC. Don't know the exact figures of the A-380 but imagine a plane with lighter weight as the A-380 can produce mor turbulences than the A-380 itself. So no extra heavy or something else to be added to the ATC ID.

Quoting Jorge1812 (Reply 8):

The heavy callsign is based off MTOW. Most 752s are not over the FAA definition of "heavy" at 255,000 lbs, only the heaviest 752s have a MTOW over that. All 757s get special spacing by ATC regardless of whether or not they are over 255k (FAA) MTOW.

Actually, the A380 is substantially larger than the C-5 and AN-124 in terms of takeoff weight, which is important when dealing with wake turbulence.

Requiring more seperation is a big deal, as a major selling point of the A380 is to allow more flights into slot-restricted or other congested airports. An increase in spacing could negate that advantage.

Of course, how the A380 will impact operations is yet to be seen. It may be that smaller aircraft must increase their spacing from it, but that a 747 could use the same spacing as with another 747 (which would be a boost at those congested airports). Untill the final procedures are out, no one can really say how big of an impact the wake of the A380 will have.

Well, a little off-topic.

If the A380 will get "Heavy heavy" or "Super Heavy", does An-225 have "Heavy heavy heavy" or "Over-super heavy"?

Exactly! If Airbus had said from the beginning something like "Our goal is to keep the WhaleJet's wake turbulence the same or less than that of the JumboJet but, given the significant increase in MTOW, it will be a challenge." then the Airbus bashers wouldn't have the opportunity that Airbus have handed them. In the end, it doesn't matter what Airbus say or what the Airbus bashers say about wake turbulence. What will matter is separation spacing.

Quoting Dw747400 (Reply 10):
It may be that smaller aircraft must increase their spacing from it, but that a 747 could use the same spacing as with another 747 (which would be a boost at those congested airports).

This is plausible. It shouldn't be difficult for Airbus to persuade the authorities to let a JumboJet follow a WhaleJet with the same separation as between JumboJets. Any airport with scheduled WhaleJet service will have enough JumboJets operating that ATC can slot a JumboJet behind a WhaleJet and save the WhaleJet from needing two landing slots. It's a bit of extra work for ATC and may mean that a WhaleJet occasionally needs to circle for a few minutes until the next JumboJet arrives, but it would save slots. It would be even better if it were found that other heavies could safely follow a WhaleJet at the same separation distance that they would follow a JumboJet.

It's remarkable to me that folks perceive the spacing issue as some sort of "Airbus Bashing". Bottom line is that, at least for now, based solely upon an engineering, data-driven analysis of the wake turbulence that the still-experimental aircraft currently produces, the thing requires more spacing than a 747. Ultimately, more permanent rules will be drawn up in various jurisdictions, based on an analysis of the aircraft as certified (and hopefully not too much politics) as to just how much spacing is required under various circumstances from various aircraft, which it will be up to the controllers to learn, remember and implement.

I think that the original poster's question was a fair one, because he apparently didn't know the answer. And until the new rules come out, either will we. I suspect that as far as how the controller addresses the aircraft over the radio and the aircraft addresses the controller over the radio, which is what the poster is asking, it will be handled just like any other heavy, e.g. "Speedbird 101 Heavy". The aircraft crew knows it's a 380, the controller, perhaps reminded by the designation, can look and see that it's a 380, the controller is required to give speeds and vectors (e.g. instructions) to maintain the spacing, so what's the big deal? Certainly when speaking to surrounding aircraft, he can identify the kind of a/c, as in "Clear to land Runway 4L, you're number 2 following a heavy A380." I don't suspect that there is a need for anything else, but if so, they could do what they did with another special aircraft: "Speedbird Concorde 193, New York Departure, Radar Contact, Climb and Maintain 5000." See, no biggie.

ATC at these facilities don't just have to worry about making a little extra room for the one flight an AN-225 makes into an airport, they will have to worry about it every few aircraft...

The spacing issue in and of itself is not bashing. However several members have used that topic as a spring-board to "talk-up" the negatives of Airbus and the A380 in particular. A fact is a fact and does not constitute bashing in its own right. But couple that fact with a skewed "the sky is falling" attitude and you have the making of an overblown situation. Yes the seperation of the A380 is greater than the 747, but that may change, and even if it were, unitl the details are finalized, all else is speculation.

Generally, when ATC provides information to one airplane relative to another aircraft's size/weight, the type of aircraft is specified as well.

Example:

"Delta 123, you're following a heavy 767 on a six mile final..."

Saying "heavy A380" will get the point across. ATC will give at least minimum separation (whatever that ends up being) and a "caution wake turbulence from a heavy A-380" will, you bet, be heeded by any flight crew behind it.

RE: "Heavy-Heavy" Callsign For The A380?

Sun May 28, 2006 1:15 pm

Wake Categories (or weight categories - never seen anyone actually referring to it in ops) are determined by ICAO. The FAA or JAA or anyone indeed cannot change those standard categories on their own. If a change is required it will have to go through all the normal ICAO rule change procedures.

NATS/CAA however operates modified categories in the UK in that mediums are split into upper and lower mediums. But they are still medium types. Upper mediums are there to categorise types like B752 where in the rest of the world causes confusion as to what wake category it should "really" be in (NO they are NOT categorised according to the factory spec MTOW). An unbinding ATC convention is that if the B752 is the leading aircraft it is a HEAVY. If it is the trailing aircraft it is a MEDIUM. (FAA follows this convention as well as most countries.) Since this is an odd ball exception that is non standard to the 4x4 "wake separation grid" it is only listed as a footnote to the grid and is prone to error by inexperienced SATCOs alike. That's why the NATS/CAA have decided to formalise it and use a 5x5 grid.

Another thing is very few places in the world actually suffix callsigns with HEAVY. It's only use is to remind controllers it's a heavy so he should exercise caution or give extra spacing. The wake category is written on the strip anyway. It's only being communicated to the pilot in the aircraft trailing the heavy only if he's a little too hot and may lead to a loss of separation, particularly on final. Otherwise we shift heavies just like any other aircraft.

In ATC research our primary goal is to devise ways to increase capacity to cope with increasing demand while maintaining safety. This can be done partly by reducing the amount of RT. It's a different world today since they first devised the categories and these peculiar rules to suffix callsigns. Knowing the callsign/type/wake cat in your sector is now part of ATCO's basic situational awareness. With 20% of all aircraft being heavies (up to 60% in some asian airports) instead of 2% when it all started, suffixing heavies doesn't mean as much any more as before. Omitting unnecessary phrases on RT may give you that little bit more to shift an extra aeroplane.

Yes, quite a bit of testing has been done. Analyses are still being done on the data. The initial analyses have produced results that were not what Airbus had hoped for, therefore more analyses and perhaps more testing.

That remains to be seen. There have been 159 WhaleJets ordered, zero delivered, and 26 deferred (by AF, UPS, and VS) with rumors of possible cancellations. Until and unless there is a flood of WhaleJet orders after EIS, it would be optimistic to predict that there will be hundreds flying. Since Boeing announced the SuperJumbo, the only VLA orders have been freighters. It may be that both Airbus and Boeing overestimated the VLA market and that the real widebody action will be A350s and B787s.

Using the term Heavy is a non-standard term used in RT mainly by the FAA controllers or operators. Most controllers world wide dont need to be told this little bit of information in every radio call, they can see from the flight strip the aircraft type and ICAO wake turbulence category.

FAA carrier pilot sounds like armatures on the radio when they use the term outside the area they are required to, it just clearly shows they are not familiar with the rules of the airspace they are in.

The other problem is that the heavy category is the FAA heavy category is not the same as ICAO, or the UK CAA, so some operators incorrectly say they are heavy on the radio when they are not.

The disignation "Heavy" is only used on intial contact With ATC units.
So it would be:

Initial contact:
"Schiphol Tower, Singapore 380 HEAVY Holding point rwy 24, ready for departure"

while further contacts would be without the "heavy":
"singapore 380 passing 2000'"

As a pilot yourself you should know that the reason for the suffix "heavy" is so that ATC knows to apply extra separation without having to refer to data strips all the time to check a/c types. If the A380 falls requires more separation that aircraft currently in the heavy category then it will require a new suffix. This is likely to suit the makers of the aircraft anyway as it will put them in a class by themselves and they will be elite once more just like Concorde.

First of all, it's the same issue, why would this a/c require any special regonition when there are aircraft that are bigger and heavier?

I'm not saying it needs special recognition, but it will require special attention in the same way that Antonov's receive...

Take here at EWR for example. We see the AN-124 maybe 6 times a year. Each time it comes in it forces ATC to alter the spacing to provide a little more room for the trailing a/c. When it leaves it requires a little extra time to do the same. Of course no one makes a big deal about it because it happens so few times a year and the controllers can deal with just one plane.

Now, when all is said and done with the regulatory agencies and they conclude that the A380 will indeed require greater separation minima, imagine the headache this will be at places like LHR and LAX that are expected to see A380's all day long. Imagine the delays if a/c following an A380 to land requires 10nm in trail, and every 3rd or 4th plane is an A380... You can see why people are making "a big deal" about it.

I'm not saying it should be referred to with the suffix "super heavy" or something, but you can see how if the A380 has wake turbulence as predicted it poses a greater headache than a handful of current "super heavies" already flying.

You are taking two assumptions for granted. One is that the WhaleJet will need greater minima than the JumboJet. The other is that WhaleJets will be common. I'll take very long odds that WhaleJets will not be "every 3rd or 4th plane" at any airport in the world. I don't think there is an airport anywhere in the world at which the JumboJet is the 3rd or 4th airliner.

From my purely British point of view, the conversation from the A/C to the tower would be along the lines of....

"Oh hello tower. This is xxx airways A380 hea oh, heavens knows, you must know we're in the vicinity because, we just must be filling your radar screens. Now would you be so awfully kind as to point us in the general direction of...."

The big deal is that there are going to be hundreds of A380's flying into the most congested airports in the most concentrated airspaces. ATC at these facilities don't just have to worry about making a little extra room for the one flight an AN-225 makes into an airport, they will have to worry about it every few aircraft...

That doesn't even make sense. An airplane behind a giant like the AN-225 is in the same situation as an airplane behind an A380, regardless of how many there are in the world. They don't base callsign suffixes on #s built.  sarcastic 

If you're talking about the seperation problem, sure... but it has nothing to do with callsigns.

Actually C-5's "Grace" alot of civilian airports... probably more than they do military bases. So, my friend you are wrong.

Quoting ShowerOfSparks (Reply 33):
As a pilot yourself you should know that the reason for the suffix "heavy" is so that ATC knows to apply extra separation without having to refer to data strips all the time to check a/c types.

Well, the other main purpose is to warn other pilots. ATC knows what kind of planes they're working, they have to. It's either on their screens or in their heads, they aren't gunna rely soley on a callsign to tell them something. Besides, plenty of heavies neglect to use the "heavy" callsign except when checking on.

The vast majority of times you'll even hear the term heavy is when the controller is talking to another aircraft. For example, "caution wake turbulance, heavy 767 5 west of the field." They won't say "no, seriously, really use caution... heavy heavy heavy A380 departed previously."

Simple fact of the matter is that there's no need for a new suffix. Controllers can give extra spacing based on a/c type, pilots knows what an A380 is... there's no problem here.

The fact remains, they are all STILL BIGGER THAN THE A-380!!!

We are not insulting your beloved A-380, we are just pointing out the simple fact that it IS NOT THE BIGGEST AIRCRAFT THERE IS!!

Do you even bother to read through the rest of the thread before posting? I already pointed out the AN-124 and C-5 BOTH have lower takeoff weights than the A380.

Quoting Slz396 (Reply 30):
MORE FLIGHTS???

I think I phrased that wrong. The goal is to allow more people with the same number of flights that currently visit a slot restricted airport--BUT, if the increase in spacing reduces the number of flights, then you really can't increase capacity.

The main reason for the A380 is to allow for growth in air travel with what amounts to a minimum change in infrastructure (compared to additional runways, the A380 improvements are small!).

Perhaps a slightly less takeoff weight has almost nothing to do with landing seperation. Think of the 757.....it is not classified as a "heavy", but controllers almost always give smaller aircraft greater seperation if they are following a 757, even though it is not a "heavy" aircraft!! If you are in a 737, the controllers are going to give you the same (or close to it) seperation whether you are following a An-124 or an A-380........so to get back to the original thread question, why would it need a different callsign???

Wingtip vorticies do not vary in magnitude by the weight of a specific aircraft. They will vary by speed, but not by weight. A 777 at MGTOW will produce the same vorticies it does at landing weight (if at the same speed....)!!! So, weight has very little to do with the vorticies produced....it is the wing that has everything to do with it. Until the A-380 enters in service, we won't really know how much seperation it will require.....but the fact still remains:

I guess not...
Maybe someone needs to say this, the A380 will get nothing special! The only aircraft that will are the ones stacked behind it. As already posted, its not like it is going to tie up airports or anything. Not every airport in the US will see the A380. So, in sum...there is no and will be no brand new special callsign for the A380.

Thats what I said here.

Quoting Jorge1812 (Reply 8):
The term heavy doesn't mean that the plane has to be heavy. It's just added to the ATC ID to recognize the plane as one which produces heavy turbulences behind and other, especially smaller planes, have to keep a big distance to avoid problems. That's why the not so heavy 757 is called heavy on ATC. Don't know the exact figures of the A-380 but imagine a plane with lighter weight as the A-380 can produce mor turbulences than the A-380 itself. So no extra heavy or something else to be added to the ATC ID.

A shame that this isn't the last senseless thread on the A-380. Maybe I start Will the A-380 get special runways/flightpaths/terminals/airports? soon  Wink
