Well, or whatever I shall call it. What I'm asking for is the second sequence of numbers/letters of an aircraft type. For example Boeing 737-3Y0 or Airbus A319-111 or 757-214. What would be the meaning of the 3YO, 111 and 214 in those sequences?

Double answer.

For Boeing: in 737-3YO the 3 means it's a 737-300, the YO is the customer code. Every airline that buys a plane from Boeing, gets assigned a customer code. e.g. Delta is 32, SAS is 83, Southwest is H4, etc.

For Airbus: In A319-111 the first 1 means it's an A319-100, the second one means it's equipped with CFM engines (every manufacturer has a different number, GE is 0, CFM is 1, P&W is 2, IAE is 3, RR is 4 and Engine Alliance is 6), while the third one means it's the first version of the engine on that plane.

Now what about the 340-343X? What's the X for?

Something awful.

The X would mean it's a higher gross weight version of the plane in that case. I thought the 3rd number in the Airbus case was the number for that particular thrust variant for that engine?

Types flown: B738, B772ER, B773, B77W, B744, A310, A320, A321, A332, A333, A343, A388

It doesn't exist !  Wink It's either an A330-343X or an A340-313X, but no Rolls-Royce-powered A340-300 has been produced to date.

There was an A340-213X which was on the books in the mid 90s, but only the sultan of Brunei bought one and in the end he cancelled the order, shelving the project. It had huge huge range (15000km+).
