Why B737-530 And Not Just B737-500?!

Mon May 14, 2001 8:01 am

I have been wondering for quite a while now, about why a plane is called FX: B737-536 or so and not just B737-500.

I've seen lots of pictures where the text includes such kind of detailed description...

So here's two questions.
#1: Why is called such an odd number...?

#2: How does the potographer know which number it has?!!!

I mean I've never seen any plane with such a label as 747-4Q3 or so...Strange.

So thanx for any clarity on this field:O)

Do a search for "last two" or "Designation", this topic has been discussed in great length during the past month or so. The last two digits are the specific operators model numbers, so if you know the reg# or operator, you can determine the model #.

The -530 means that it is a -500 delievered to Lufthansa, customer number 30. Others include:

21 - Pan Am
22 - United
23 - American
25 - Eastern
28 - Air France
30 - Lufthansa
31 - TWA
32 - Delta
36 - British Airways
38 - QANTAS

The '30' suffix that you have identified is the Boeing customer designator assigned to Lufthansa, for example the 737-530, all the Boeing aircraft in the Lufthansa fleet have a '30' suffix, 747-430, 747-230B, etc..
All Boeing customers have their own designator code, for example:

Northwest Airlines is '51'
British Airways is '36'
Iberia is '56'
United Airlines is '22', and so on....

An aircraft designated as a 747-287B, but in say Virgin Atlantic Colours may have been originally delivered to Aerolineas Argentinas (the airlines code is '87') and then acquired by Virgin at a later date. The designator code never changes, even if an aircraft does change owners/operators.

It is interesting to note that Airbus Industrie do not assign customer codes to their aircraft, they instead have a number relating to the customisation of the aircraft (its fittings, etc) so in this case a number of different airlines can operate the same type of aircraft with the same customisation code.
I love it when a plan comes together

it's good to hear that some people aren't negative about answering an already asked question.

I was wondering, when looking at photos and when I was about to send some pictures in myself, how people knew the specs for every airline...

Is there a kind of fact sheed or something like that, available on the net?

Thanx for your replies everyone:O)

If its a Boeing, MDC Lockheed or Airbus JET you can find the precise designation for any aircraft produced to date.

I find the easiest website to use is

http://www.bird.ch/bharms

Navigate to the relevent type, open the page, then do a search (edit, find on this page) for the registration / tail number and you be able to see the variant along with other details about the a/c.
