A340-300E Vs -300 Enhanced

Sat Feb 14, 2004 1:53 am

What's the difference between the A340-300E and the A340-300 Enhanced? And what about the -300X? I know what enhancements are involved in "Enhanced" but I don't know what the 300E and 300X involve.

I had the impression that all the designations mean the same thing?...

Singapore Airlines while they still had their A340-313Xs named theirs the A340-300E with the E standing for Enhanced. But these -313X are just higher MTOW versions delivered and upgradable to operators of -311 etc.

But now the A340-300 Enhanced features new interior, minor upgrades here and there and a 'new' powerplant.

Someone may be able to explain better than myself and correct me if I am wrong.

No AirxLiban

All A340s are powered by CFM engines with different ratings and maybe slightly updated ones. I don't know the models etc someone else can help with this.

The 340-200 and -300 all variants are only powered by CFM International CFM56-5C engines.

The A340-313X, which was previously referred to by SQ as the 343E, are higher-gross-weight frames with a a centerline fuel tank, strengthened wing, and the tail enhancements from the A330-200.


The A340-314, A340-314X, or whatever, the new A340-300 Enhanced, are powered by the new CFM56-5C/P. They include a completely new and updated avionics suite with LCD displays, a new FBW system with additional FBW controls for the rudder and some other basic improvements from the A340-500/600 family.

For your information, the main difference between the CFM56-5C and the new -5C/P is not the thrust or power but the time on wing and therefore reduced maintenance costs.......

MD-11,

But I thought these -5C/P are also more environmentally friendly with lower emission and this helps LX save a lot of pollution fees to airport authority at ZRH?

It is also slightly more efficient than the earlier -5C during cruising phase.

Actually, the -500/600 are powered by Trent500s

Actually, the LX A340s are not A340-300 Enhanced, they are the 'ordinary' A340-313X. SA will be the first to get the -314X.

i was referring to the A340-300E version...so it is only available with CFMs?

The LX A340s are the "enhanced" minus the -5C/P.

They are, therefore, still A340-313X, but have the other new features I mentioned.

Qantas was the first to receive an Enhanced A330-200, and Northwest the first to receive an Enhanced A330-300.

That's incorrect. All of LX's 343s before SAA's first 343 delivery have the -5C/P engines, but without the cockpit, interior, and other upgrades associated with the Enhanced model. LX will receive some 343 Enhanced.

I found a related CFM press release article http://www.cfm56/news/press/cfm02-33.htm.

Also, are you guys inventing the designation for the 343Enhanced? The -311, -312, -313 are three 340 models with three different engine thrusts. The -5C/P will have the same thrust as the -5C. So, I am not sure if the 343Enhanced will be designated as -314. In the CFM press release, it said all -5C engines could be upgraded to -5C/P. Then I suspect there is no such thing as -314. If that's not the case, then all of LX's 343s will be -314, but some of them will not be the Enhanced model. Confusing, isn't it?  Wow!

Interesting. I was under the impression it was the other way around, but I'm sure you're quite right.

Thrust rating isn't necessarily the deciding factor for the variant number, its engine model. I would assume if you upgraded a -5C4 to a -5C/P, the last digit would change.

I'm fairly sure it changes even on the 320 series models depending on the number of annular combustors installed, ie a -5B4, -5B4/P, and -5B4/2P. It definitely changes between two different engines of the same thrust for the 319 and 320, like -5A vs. -5B and whatnot.

Lastly, I heard -314, but not from someone at Airbus or CFM, so what I heard could be quite wrong.

Sorry typo up there i meant A342/3s were only available in CFM powerplants.

As for LX's, I heard they will subsequently be upgraded. I think they have all the Enhanced upgrades minus powerplant as it is not yet certified or some sort? Not sure on this.

Dynkrisolo seems to be quite right, its the other way around.

The frames have no enhancements, just the engines.

I vaguely recall that it was once said that the first few A343s for LX will not be enhanced(?)/advanced(?) but that they will be upgraded such that they will form a uniform fleet after some time. That was a long time ago though and all may have changed.

Anyway, with Airbus, the last two digits in the plane name (as in A340-313X) refer to the engine, and not the inital customer as Boeing does.

They were flight-testing new winglets for future aircraft programs, including update on the A320 family. It's similar to the winglets tested earlier on the A340 which was part of the AWIATOR (aircraft wing with advanced technology operation) research program.
