Systems wise they are the same aeroplane. Engine wise they are the omptimum engine for the mission profile.

The two engine A330-200/300 with either P&W 4168s, RR Trent 772s, or GE CF6s has better takeoff performance over the four engine GE/SNECMA CFM56-5C powered A340-200/300.

The A330 and A340 are quite similar aircraft. From a airlines economic point of view and according to Airbus itself the the 2 engine A330 aircraft is the prefered aircraft for flights under 8 hours while the A340 economic benefits kick in on legs over 8 hours.

Well, I have flown the 330 but not the 340. I think the 330 is great. And while four engines would be a little comforting over the water (especially with AirTransat's latest incident) I like the economics of the twin better.

Although I have flown on neither an A330 nor an A340, I can still say that there really can't be a solid comparison between the two. Each version of each aircraft serves different purposes, so a direct comparison by, say the A340-600, would not be feasible when compared to the A330-300. The A346 is a high-capacity long-range airliner, while the A333 was designed for medium range medium to large capacity flights. But if I had to choose between the two, I'd choose the A340 because the A340 has four engines while the A330 only has two.

i would say the A340 as it has a longer range/capacity etc.
I believe that your post is a challanging question. each aircraft is good in its own way.

The answer is quite simple, as is the case with most comparisons between aircraft, it depends on the airline. They are designed for completely different routes, so you can't really compare them. As an example, the A340 is ideal for ultra-long range transpacific operations, so for these kind of routes it is a better aircraft than the A330. For shorter, transatlantic routes, the A330 has the edge over the A340.

In light of this evidence that in the topic of A330 VS A340 I will chooose an aircraft with two engines over an aircraft with four APUs anyday. LOL

AA737-823:

Puh-leez. The Air Transat incident could very well happen to a four-engine plane. When you run out of fuel, it doesn't make any difference if it is a two-engine or a four-engine plane.

Back to the original question:

Airbus had comprised on the wing aerodynamics when they used the same wing for the twin A330 and quad A340. My impression is the wing A330 and 340 share is less optimal for the four-engine application. So, I would say the A330 is better.

I have heard that pilots complain that the A340 is underpowered. Can anybody confirm this?

Total maximum thrust for the two engine A330-200/300 with 72,000lb thrust RR Trent 700s or GE CF6s is 144,000lbs, where as the total maximum thrust for the four engine A340-200/300 with 34,000lb thrust GE/Snecma CFM56-5C4s is 136,000lbs.

This topic has been covered before and, perhaps, it would be fairer to say that the A330 is overpowered. Since part of certification of all aircraft requires them to complete their take off run with one engine down, four engined aircraft don’t need to have as much total thrust as twins. The A340 has just about enough thrust to achieve its design targets and no more. This means that it ‘feels’ underpowered compared to twins.
