Airplane Types

Fri Sep 22, 2000 12:18 pm

I have noticed that the airplanes in some pictures aren't described as let's say 777-200 but they will call it a 777-232 or something like that. What do these numbers mean? Some have letters too, like 737-3QH. Anybody know?

The -232 means -2, 200 series 32 is the customer number. So a 777-232 is a 777-200 sold to Delta Air Lines (Customer 32). What I am unsure about is on the older douglas types, they had several numbers which I do not believe were customer numbers. Like the DC-8-54 or the DC-8-55. These numbers probaly mean different T/O weights or payload (I think). Also Airbus has numbers which I am unsure of.

The -54/55/61/62 etc. is the model designation akin to the 100/200/300 etc. of Boeing. It contains no info about the customer.

Yes...32 is the customer number for Delta and 22 is the customer number for United. To Tarantine, the DC-8 designations are the variants. Just like 767-300, think of it as DC8-71. Hope that clears things up.

Airbus numbers indicate the engine manufacturer and type. So an A319-114 has a CFM56-5A5 engine, the first '1' indicating the model (A319-100), the second '1' indicating a GE/Snecma engine, the '4' indicating specifically which type, in this case CFM56-5A5. An A320-211 has a GE/Snecma but this time a CFM-5A1. An A319-131 has an IAE engine, specifically a V2522-A5.

I asked this question quite a while ago and someone told me that the last number of an Airbus stood for the number of the modification which was made to the craft after inception. I forgot who, but a Delta mechanic told me that an A310-324 had to be serviced in the hangar. When it came out, it was a -325. My post was entitled "How does an aircraft get its version number?" It was my very first post!
