What does the second number of an aircraft type mean?

Question

Ok i Know what 777-200 or 747-400 means, but what does it mean when its like 777-222 or something like that.

Answer 1

The higher the number, the more seats crammed in, which is directly proportional to the lower amount of legroom I have!

And THUMBS DOWN to losers who don't like a little humor in their lives.

Answer 2

Its the series number like a 747 series 100 SP issome sort of modification the 777-200 is another series whereas as you say 222 series would then be an improved or modified something (sorry have no triple 7)

Answer 3

777-222 would mean 777-200 and the 22 is added on to designate United Airlines.

.Lately they've been using 738 to mean a 737-800.  It's kinda like an abbreviation.  

.

A 767-223ER for example is a 767-2(00) the 23 (means American Airline) ER (extended range)

Answer 4

Its a version number.  For instance the 737 has had several versions 737-100 through the 737-900   The higher the number usually means the newer the version.   Usually a version has different design features (range, size, engine nacelles etc)

Answer 5

The last two numbers designates the airline that first ORDERED  the plane from Boeing.  For example, Qantas is 38.  They operate 747-400's with Rolls Royce engines and GE engines both are 747-438 and ER's, 747-438ER.  They also bought an old Asiana 747-48E and two Malaysian 747-4H6's which are now painted like the rest Qantas' planes.

Answer 6

It is the designation for the airline that operates that series.
