Does C/n's Matter To Photogs?

Fri Aug 30, 2002 9:21 am

Okay, I've been sending shots onto for almost 2 years.

I've read What Editors Do No.1

... and I've read that the database is being standardised (standardized <> US)
(BTW: the spellchecker is wrong, it's S not Z)
as far as possible.

I cannot, at any time, recall adding a 'con' number or MSN or any concurrent serial number pertaining to the aircraft falling off an manufacturers production line.

I find it fascinating that sometimes, within hours, that some of my submissions have been amended with the c/n or MSN in the remarks field.

Personally, I don't care....and why?
....because I'm not a Planespotter......

One of the most boring aspects of the number crunching 'game' for me was trying to confirm that the new 'cop' was not the same aircraft under a new registration. That killed it for me....a long time ago....christ, that was a librarian's job! ....Where's the fun?

I presume those who maintain a strict 'spotting' practice and require to cover
the acquisition of a 'fleet', the pursuit of the 'con number' spotter takes on a greater significance.

I do appreciate that the genuine 'planespotter' will take 'con' numbers seriously and follows their hobby to the greatest extreme by logging such detail, but I cannot concur.

Also, don't ask me to buy 'JP World Airline Fleets' or similar spotter books to fill in the missing gaps in the remarks space, because I'm just not interested.

It's just my opinion....but am I letting down?

I wonder how may other photogs feel the same way I do...?

I am not offended by addition of 'con' numbers to the remarks field, just completely bemused!

Well serials and cons don't have any magic for me, however I do recall an email to me sometime back from the corrections editor asking to provide these if possible since "corrections" in the form of con number additions are the single largest part of his workload. Since in most cases finding a con number on the net is fairly easy, I do try and make an effort - and in a number of cases searching for a particular reg has rewarded me with the discovery of a new site or information I am interested in.

I confess, I won't go to extraordinary lengths to find this info, but I'd guess 90% of my uploads do have a c/n.

Gerry brings-up a good point that has mystified me for awhile. "I'm going 'spotting' this weekend at airport XXX". Is 'spotting' the same as photography and vv?? I always thought that (original) spotters were those folks that hung around airports with their ratty spiral notebooks, writing-down tail numbers (or train locos). I don't have a problem with that, as I assume it is a respectable hobby.

Looks like the term spotting has now loosely translated into photography as well. Just a matter of semantics I guess...

Gosh you should see the number that do it in England. Aint interested in photography at all. They just pull out their telescopic telscope and then write down the number. Very Freaky  Smile/happy/getting dizzy I have not experienced it in Australia at all.

The serial numbers don't mean a whole lot to me (but hey if they want to add it, that's great). Now, customer codes ie; -432, -330 etc, it surprises me how many people don't know it, or are too lazy to look it up (and just leave -2...). All it takes is to look up the reg# in the DB or even I'm sure the DB corrections guys would appreciate it too if we put the correct code in.

I find customer numbers interesting, esp. after having flown an airline like National, that got most (all?) of their planes second hand....the layout in the cabins are simliar, but different, so it is cool to look and see the differences.

The craziest thing is to thing that the plane co's make each model different for each airline, how ineffiecient is that?

Make 'em all the same and lower the prices so it is cheaper to fly  Smile

Hi all,

As with most (it seems) of the photographers here I have no interest in serial or construction numbers. I'll sometimes put them into the remarks/comment field when I have nothing else to put there since as others have pointed out, this info is often (without looking very hard) readily available. has been noted that in England there are many 'spotters' who have no more interest than to just write down tail numbers or registrations...and yes...most of them do have telescoping telescope thingys and tatty spiral bound notebooks. Maybe it is a particularly English/British trait as I don't see this elsewhere...

And baffles me too when some 'Nutty Norman' (a term Gary and I coined for one such individual we encountered at LHR last year) screeches up in his (usually his...although there are some nutty Norma's too) car and whips out his telescope (or sometimes just one half of a pair of binoculars - how weird is that...I mean do they pool their money and then tear them apart!) only to scribble a number in a book and zoom off somewhere else.  Nuts

Life's dangerous. Get a f**king helmet!

I am really fascinated by C/n`s, it makes fun to dig for them through several books and/or internet sites, especially when the the a/c in question has a rich history.
One of the best sources for detailed informations is the "Aviation Letter" by Lundkvist Aviation Research, imho.
The search for a C/n also reveals that even with more than 250.00 images there are still HUGE gaps......

You guys should appreciate that it is a hobby and each to his/her own. Just because you don't do it doesn't mean it is "freaky". Many people will wonder why so many find it fascinating to stand outside an airport for hours on end to take yet another photo of a "boring" airliner. By the way "standardized" is correct as well. It is not the US spelling.

That may be your view but knowing what airline the aircraft was with before may be of great interest to others. Just because you don't know the information does not mean its boring or a librarians job.

As a spotter I would like to ask any of you that think its freaky to come over to Hong Kong and say that again. Freaky, is taking photos for and no other reason !!

I do not collect con numbers but I do follow them.

As for Aviation Letter, YES its the best !!

I don't have interest in registrations or c/n's but since this is the biggest aviation photography database on the internet I do my best to find these numbers. I use the fabulous Bill Harmes site and in a question of seconds I just copy and paste the information I want to the remarks field.

It's a question of respect for this site, narrow minds are not for me.

Maybe a reg spotter can step forward and confirm this, but your photo has a value beyond that which you yourself seem to recognize. The photos are often used by reg spotters to trace the history of individual aircraft. In the process of doing this, detailed information gets appended to the database, and is stored in their personal records. That you say you don't care about this, yet you brought it up as a subject for discussion is interesting. So lets discuss.

How do you feel about dash numbers? Do you research to the dash number or (in the case of military) block number level before posting your photos? This is also an area of interest to those with an eye toward detail and accuracy. In the case of airliners, those who don't know why customer dash numbers exist probably should take a marketing course. Do you think Jetblue's Airbuses have TV's built into the seats because someone scribble a note on the contract?

In the case of the US military, the differences are quite subtle, but also complex. A course could be given on this subject by itself. The F-16 is perhaps the best recent example of airframe variation due to block number differences.

I don't set out to include msn or con numbers when I post my photos. However, when researching an older image, it is often the best way I can identify the aircraft and add interesting information about it.

I'm not a spotter, and the hobby is not common here in the States, but I do believe that the aviation hobby in general benefits greatly because of the spotters of the world. There would also be far fewer great aircraft publications both on the net and in print, without their participation.

I would like to point out that as a photographer you have one thing in common with spotters that deserves some consideration. You are now BOTH under the watchful eye of security. How you BOTH behave in proximity to airports has more to do with the longevity of your hobby than anything else. Pointing the finger of criticism at each other will not accomplish anything positive.

I put in the serial numbers as a matter of habit - since we generally look up the exact aircraft type (like 737-33V instead of the plain vanilla 737-300), the serial number is generally right there, so why not include it for those that are interested. not to mention that it can be usefull to determine if it is a first or last one in the series, which is a category on A-net. I'm also interested in seeing the same plane go through various ownership changes over its career. Someone who works for a constructor might come on to this site and seeing a serial number, might recognize, and say something like, "Hey, that's the one we were building when may baby was born!", or something like that. Anyway, it doesn't hurt, and some people might be interested, so why not put it?

Hi all

When ever possible I put the c/n in the remarks field, as I like to follow the lifetime of an airliner. With the cn the aircraft is for me somehow 'identified', his history can be followed back until its first delivery and can be documented in A.N. by searches like that

Special thanks to all contributers, which but the cn to the photo ! … but I don't mind if you don't do it, I always enjoy your photos anyway!

regards, Eduard

P.S. In my earlier years I used to read the Aviation Letter regularely and I am glad to hear that it still exists !

I prefer reading the m/f date for each aircraft, sometimes its quite interesting to know when I plane is built, I guess.

Apart from that, c/n numbers don't hold any interest for me.

Construction numbers don't interest me that much (if I want to know a construction number for a given registration, there are other sources) and to be honest whilst I often look up the customer number (e.g. for Boeings) even then with the information in front of me I rarely document the construction number in the comments. I guess its partly lazy of me, partly that I just don't like to see construction numbers cluttering up the comments area. If airliners was going to do construction numbers properly, there should be a database field for it, and not have it put in the comments. In all honesty, I think that there's other sites (e.g. Bill Harms) that deal with constructors numbers to the extent that I'm not really sure its necessary on airliners. I guess what I'm saying is that if I want a construction number, I wouldn't come to airliners to get it.

All the numbers will help tracking the plane thru its history
A photo may be a great thing but it's greater if instead of a snapshot ( a still object ) one can follow the evolution of a "living" being
So clearly I want the numbers and wish that those who fed them here will continue : many thanks to them but same thanks to others who don't  Laugh out loud
PS : sometimes it's really exciting to track the whereabouts of a "mystery" only to discover that one character or digit is mistyped :-(

I also put in the c/n's as a matter of habit. Sometime I recognize an airplane that has changed hands and I did not even know about it until I see the c/n. I just pull out the old JP Fleets book and look up the c/n as I am entering the rest of the info on the photo. This does not take hours, just a few minutes.

I think I share the views of Torsten, Luis, Gary, Charles and Eduard about this subject.

I don't collect c/n's by myself, but I try to include them as often as possible, even though I'm very well aware about my own laziness regarding c/n's for Soviet built a/c's and bizjets.

And, even if I don't collect c/n's, they could give me satisfaction when I check them out!

I can mention an example from this summer,
when I was at Paris-CDG and took a photo of an AOM DC-10, F-GHOI.

This one turned out to be the former OY-KDA of SAS, which was the aircraft I flew for my first visit to USA, 16 years ago, and this was also the first DC-10 that I ever flew with, which meant that this information is special for me.

Therefore, when I upload photos to, other people might find aircrafts that are special in their lives, and I think that they, in most cases, will welcome if such facts are displayed together with the photo.

After all, this site IS a database, and what is c/n's if not data?

Thanks for your far...

Just because you don't know the information does not mean its boring or a librarians job

Sorry Daryl, you may have misunderstood me. Detailing something that is supernumerary to 'avaition photography' is boring to me.
I used to do it. I grew to hate it.

I didn't quote 'planespotting' as 'Freaky'..... it was my fellows on this thread.

I have many planespotter friends locally and down in England.
Would you believe me if I told you that I am a 'Freak' in their eyes?
Yep, I am.
They rarely come across a 'plane photographer that doesn't jot down registrations
or serials. ...

...and yes......split binoculars are not unusual....commonly seen on spotters
at Scottish airports too...... and it's not funny, that's just the way it is .......  Wink/being sarcastic


Dash numbers? Yes, I will add that, not just add Boeing B737-3.. but if I know
or find out its a 330QC or whatever, I'll note it, because that's what it is.
I know exactly the type of car I'm driving, but I don't care about the body number
or the engine number.
Same kind of thing, isn't it?

As for general aircraft reference, I'll stick to buying the little (UK) Civil Aircraft Markings
every year. It's sufficient to keep me up to date, albeit, maybe a year out.
It doesn't come the c/n's, I don't think it ever did.
It was always the specialist publications that contained the c/n's.
Okay, we're all on the net now, it's easier to get that kind of stuff if you really want it.

So, I'll let the enthusiasts have their day and let them add to the Remarks sections
with pleasure.
I'd rather that someone else do it if they find it 'fun'.

I don't want to specialize on construction numbers!

I'm also with the majority, sort of! I have an interest in what c/n a new aircraft may have so that I can trace it's history to provide that info in my upload text, I always try to be as accurate as possible with the details I add to my photos. However I try to put the c/n, l/n and date delivered to current customer in every upload I do.

It certainly adds a little technical info related to that aircraft that may certainly be of interest to some.

If there is some way of adding these fields to the upload page I would believe it to be a good idea. It would enable us to then search by c/n for those who are interested (although a rego search works just as well).

Peter Vercruijsse, with my support, has asked Johan to add an additional field to the database to hold CN details. If this gets done, it would be displayed on the photo view page alongside the registration number, if entered, else not displayed if left blank.

We appreciate it when photographers do fill in this type of detail, but realise that some do not have the interest or the time to do so, and we're cool with that.

We could add all kinds of information to these photos, but, as was alluded to higher up in this thread, we are first and foremostly an aviation photo database. In the case of CNs, though, we have had numerous requests over the years to add this information as a separate, searchable field.

Registrations and construction numbers are the ultimate means to identify an aircraft, or in other words, to make it individual, set it apart from something else.

When you start having an interest in aircraft, you begin to make the first separation already: you set them apart from cars, trains, people, and anything else. Some people (like my wife  Love ) stay in this stage. Many people go to the next stage: they see that some aircraft are carrying Continental Airlines titles, and others American Airlines. And then suddenly they see a Skymaster Airlines aircraft, wow, that is interesting. Why? Because it is different.

And they also see that some aircraft have two engines under the wing and others two on the aft fuselage. On inquiring they find out one is a Boeing 737, the other a MD-80. They try now to keep them apart and find it quite a sport. They start making a photo of an aircraft now and then, but after a while they have enough shots of Continental Airlines Boeing 737s and American Airlines MD-80s, when you got one, you got them all.

Then they see somebody pointing a telescope at aircraft and jotting down something in a spiral notebook. They are curious and start talking to the guy. He happens to be British and explains to them that he notes down the registrations, or "numberplates" of the aircraft. When asked why, he continues to explain that you can find information about the aircraft with that, like the aircraft type, owner, build date, etc. He gives them some internet URLs and some book titles which they can use for that.

They now note down a few registrations themselves to look them up at home on one of the URLs. They find out that they saw two different types of Continental B737s, a 737-524, and a 737-3T0. Next time when they go to the airport they try to spot the difference, and indeed, one is longer than the other. They pick up on photography again, because, with the help of the registration, they can add details to their photos like the exact aircraft type, and the registration is a good means to classify their photos. They now also have a means to find out the type of an aircraft they didn't recognize (ah, is that a Cessna 172). Smokin cool

In one of their references they see that one of the Continental 737s, N17356, previously had a different registration, N320AW. How do they know that, they ask themselves. After some study they find out that the registration of an aircraft can change, but that all aircraft have a unique identity, the construction number, also called manufacturers serial number. With this number it is now possible to follow the whole history of the aircraft, from roll-out to broken-up (or worse). And they also find out that this number forms the basis of all aircraft history research. Now they can find everything about an aircraft what there is to know.

Basically, I have followed this path as well, and I have never been looking back. It is the most fascinating hobby I can imagine!

Now to how interesting would the site be, when we wouldn't include aircraft types at all? Quite boring I suppose. So we decide to include aircraft types. How do you know the aircraft type? By looking-up the registration somewhere. But sometimes the same registration is used on different aircraft of the same type. How do you know which is which? By looking-up the construction number, and with the help of that the history.

Look at these examples:
You see a Cargolux B747-200 with the registration LX-DCV. After looking it up in the references you find that there are two different LX-DCVs, cn 20887 and cn 21650. With the help of the cns you can verify the histories of both, and you find that 21650 carried LX-DCV from 1979 to 1987, and cn 20887 from 1991. The first is a 747-2R7F/SCD, and the second a 747-228F/SCD. You can now identify these two pictures:

....... I never cared about c/n or msn because I used to be the 'only one' doing it....or so I thought. But after working for the last 29years and raising a family and not having time to fully investigate every plane/jet/Heli I've seen, what I've found out that there are plenty of people in this hobby and they are perfectly fine with me to have their own webpages, books, list, etc..and I'll glady pay them to have done all the work and I'll purchase the book or visit the webpages and use their research, so it was worth it for them to do it...make sense..?

For me personally i is a combination of both. When I have taken a picture of an aircraft somewhere. It is interesting for me to know the history of that aircraft. When is it build, where did it fly and by which airline?
I can understand that it is difficult to get al this info if you don't know where to look after it. Happily enough I am one of the editors of
(direct link in my member profile). At this site you can see in one search: the serialnumber, the complete history, the type and the current status. So for me it is not difficult to get this information.
If you are interested?? Take a look and try it. Maybe you enjoy it when you see it isn't that difficult.

Best regards

Aaaaah Peter, you spiked a memory. Remember when we had 'discussions' about this awhile back? I agree that there is a distinct difference (for example) between a 733 and a 735. BUT, can even the most informed spotter (OR photographer) externally distinguish a 737-3T0 from a 737-3H4 without having the reg#s memorized? I seriously doubt it.

I do believe that reg#s are important, MSNs/LNs offer historical significance (secondary), but Customer Codes?? I still don't get the point...

I read a story a year or two ago about the owner of an extensively restored aircraft. This plane had few, if any legitimate original parts in it. It was in effect a replica. The guy bought a derelict of the same type aircraft at a small airport on the cheap, removed the I.D. plate from it and applied it to his replica. He then abandoned the now unidentifiable derelict aircraft at the little airport and flew around quite proud of his restored antique aircraft, now worth quite a lot of money.

I'm told that when it comes to automobile collecting, the I.D. numbers are a large part of the game, meaning the difference between a more or less affordable auto, like an A.C. Cobra replica, and the much, much, more expensive pedigreed original. Of course that doesn't mean when I photograph one I run around looking for the I.D. plate.

Still, I would like to rev that sucker up and pop the clutch once or twice.

(I know, I Know, you thought I was too old to think like that).

Boeing has opted to include their customer codes in their type designations, so all civil aircraft registers include them as well (just check a Boeing on the FAA register website). And all serious aviation publications do the same. And as is also now considered a serious (on-line) publication, so why shouldn't we be doing the same?

On the other hand, e.g. Fokker assigned customer codes to their aircraft as well, e.g. F-27 cn 10406 has variant code 6153, so could be called a F-27-6153, but these numbers were not published and not taken-up in civil aircraft registers, so the aircraft is just called a F-27-600.

I can just say that c/n numbers are the best way to track down the individual aircraft´s history.

I agree that good shots are nice even without this information, but at the same time correct information makes the search possibillities in the database a lot better.

Hey All,

I started my aviation photography hobby by visiting local airports to watch planes fly by. I didn't take pictures, I didn't write down reg numbers. I was just hanging around the airports inhaling Jet-A.  Big grin
Then I started taking pictures, writing down registration numbers just to check what year that particular aircraft was built.
And when I turned around I had collection of over 10 000 pictures of commercial aircrafts. I have so many pictures but I didn't know what I have. What airline, which aircraft, where taken, quality of the pictures etc. So I started writing down registrations of aircrafts I took picture of. When I developed my pictures I've noticed that some aircrafts doesn't have visible registration numbers (egz. Northwest DC-9s). I checked the date in my notepad, saw all registrations for NW DC-9 I took pictures of that day and if I wasn't sure which aircraft it was I went to Bill Harmes webpage to compare my fleet number with registration number.
When people were asking me for particular picture to show them or scan it for them it was taking me few hours to find that one picture. This mobilized me to create picture database.
Right now I am in progress of entering data to my dbase. In 3 months I've entered detailed information about 2700 pictures. In those 2700 pictures I have 987 unique registration numbers from 49 different airlines, taken at 17 different airports. To complete my dbase it will take me probably another year or so. I had no idea that I had pictures of airlines that don't exist for years. Its just nice to learn about life of an airliners. For example Boeing 727-227 Adv N428BN delivered to Braniff in December 14, 1973, then went to Poeple Express as a N553PE then went to Trump Shuttle as a N926TS and then was with USAir Shuttle till it was retired from the Shuttle in January 2000. But this is not the end of its service. Right now this aircraft is flying as a freighter with N793A.
Well, I wouldn't know this if I didn't create my picture dbase.
I have 9 different reports in my dbase. I always print out one of them before I go out for spotting. Its very helpfull to have it handy while spotting, especially when you are fleet collector. I'm collecting only US Airways fleet and Delta  Smile
I'm doing very well  Smile

Ok, here are screen shots from my dbase:

This is report with detailed aircraft data

In this report I have description of quality, weather and action.

Here, I see airline, aircraft, registration, operated by, color scheme and how many pictures of this particular aircraft

Here I have data about pictures by airport. I have at least 10 000 pictures to go so please don't make fun out of me that I have only 1 pic taken at ZRH  Smile

To summarize all this crap I just wrote I wanna say that C/N and L/N are very important for me.

I am a photographer and a Bizjet spotter.... I dont like how people in England spot EVERYTHING with wings.... I was in orlando and saw a couple that were spotting Cessnas and Cherokees and were whining because they couldnt get the registration of a Blimp!

I've been in the company of people in England spot EVERYTHING with wings and without wings

eg. I've been with registration collectors who where taking registrations from the baskets of hot air baloons that were tied up an stowed on a trailer behind the vehicle at a motorway service station. ......and they tried to 'con' it too!

It just goes to show, there are extremes and there are extremes....

Can someone help me understand what a "line number" is and how it differs from a "construction number"?

As for me, I don't place great significance on those #s however i do try to get a reg # so that I can find the plane's delivery date. Registration #s are an easy way to identify planes and it's nice to know exactly how old a certain plane is. This is why i hate shooting planes directly overhead: here in the U.S. they dont paint the reg # under the wing so I'm pretty much lost. Sometimes I'll take a couple different shots of a plane so that if the "good" shot does not clearly show the reg # due to the angle then I can still get that # from the other shot.

Of course I respect those whose hobby it is to collect all data relating to a certain aircraft. if the Editors want to put c/n's on my remarks I guess its ok but I'd be happy without it.

Construction numbers are very important, I show you the reason why:

Five years ago I started to cover the Eurocopter EC135-Production. For each line-number I tried to get the full aircraft details, e.g. the current registration, the current operators and even photographs for a full documentation.

For example: I have full details for c/n 0195 "N45PC" and c/n 0197 "N2C", but still no details for c/n 0196 and someone only reports that he has seen an so far unknown Eurocopter EC135 with reg. "N552BA" (but not whether the c/n is indeed 0196), it only helps very little, because "N552BA" could also be c/n 0197 re-registered from "N2C".

Therefore I always check c/n and add them if possible!
If you are interested in my c/n-work, have a look at the EC135-production-listing at my 1st unofficial EC135-Page (c/n 0001 to 0100) (c/n 0101 to 0200) (c/n 0201 to 0300)
