Aircraft Numbers & Letters Following Type Numbers

Mon Oct 04, 2010 10:54 pm

Very much enjoy being a member of a.net and learning so much from the experts out there. I will post a question and look forward to learning something new. What is the significance of the letters and numbers that follow the aircraft type numbers. For example: B747-433M; B777-3ZG/ER; B767-332/ER; A380-861; Sukhoi Su 26M; A340-642; B757-2K2. Do these numbers and letters discribe the seating layout or the engine type? I assume ER=Extended Range and RJ=Regional Jet. I don't see any postings that address this specifically. Thank you in advance.

Boeing is the customer code and Airbus is the engine type

For Boeings, the two digits after the series number indicates customer code, i.e. '33' from 747-433M is for Air Canada, and 'ZG' is for V Australia. On Airbii, the last two digits indicate engine manufacturer, and engine version, respectively, i.e. '42' from A340-642 indicates the engine is from Rolls Royce, and it is the second version of that engine. The final digit in the Airbus codes also imply the relative age of the aircraft; for example the A320-214 is much newer than the A320-211

Some letters:

B (Boeing) = higher-weight, more capable versions of many earlier types
C (Boeing) = Convertible (can be switched from pax to cargo config and back)
D (Boeing) = Domestic (used on 747 only)
E (Airbus) = updated electronics, higher gross weight (on A330/A340)
ER (Boeing) = Extended Range
F (everyone) = Freighter
HGW (Airbus) = higher gross weight
LR (Boeing) = Longer Range
M (Boeing) = Combi (pax on half the main deck, freight on the other half)
R (Airbus) = extended range
X (Airbus) = higher gross weight (on A340)
X (everyone) = experimental or future type

The letters A and W are also used informally, A to describe "non-ER" versions of Boeing planes, and W to indicate that a particular aircraft has winglets.

Quoting B737900 (Thread starter):

It's up to the manufacturers how versions of their aircraft are designated. In Su-26M, the M probably means Modified and other suffixes on Russian aircraft typicaly mean things like Uprated and Long-Distance, in Russian.

Very much appreciate all the expert information in the posts. Thank you all. I ran across two types today on a.net that I really can't decipher so will ask one more time for some help. Boeing 777 - 3F2/ER and (here's a tough one) Embraer ERJ - 190 - 100 - IGW - 190AR. Thank you.

Boeing 777 - 3F2/ER

777-300ER with customer code "F2", Turkish Airlines.

ERJ - 190 - 100 - IGW - 190AR.

Don't know about AR but "IGW" normally denotes "Increased Gross Weight".

And on your Sukhoi SU26M the M basically stands for "modernized", you see that in Migs (MiG 21MF) Tupolevs (TU22M3) and Illyushins (IL76MD) too.

ERJ-190-100IGW 190AR

Embraer Regional Jet 190, -100 version, Increased Gross Weight sub-version.
Alternatively called ERJ-190AR which seems to stand for 'Advanced Range'.
Airliners.net is lumping this all together, which is just silly.

Appreciate the shout-out!


As usual, any updated information is much appreciated. For example if anyone wants to compile Canadair and Embraer info I will put it up and give credit.
