Yes Im aware of that, but was the a340 somehow "lighter" despite having 4 engines instead of being a Trijet?

The A340-300/200 was a much newer design and lighter than the MD-11 whose structure was based on the DC-10. The engines were smaller and had much better cruise consumption.. we used to joke that the A340 had 5 APUs, 4 controlled by throttles.
Also the more engines you have, the lower max thrust needed. to put it simply... for a twin, in an engine out situation the remaining engine has to produce twice the power. For a triple, each remaining engine needs to produce 50% additional power to provide thrust equal to three engines.. for a quad jet.. the margin is 33% additional thrust.

I am thinking a MD11 to A330 pilot conversion would have taken longer.
Also, maybe some of the A330/A340 spare parts could have been in common too? But I may be wrong here.

I also wonder if the a340 wouldve had a much harder time selling if it was a trijet, and what would the naming be "Airbus t330, t standing for Trijet"?

I imagine if MD had re winged the MD-11 from the beginning rather than just putting wingtips onto a DC-10 wing, it would had more range and better fuel efficiency and would of sold more.

Training a few hundreds pilots shouldn't have been a factor compared with the difference in operating costs.
It wasn't the 342/343 that killed the MD-11: it was the 777, which had taken the lead over A340 deliveries even before the end of 1998 despite the A340's ~24-month earlier entry to service, 3/93 against 5/95.

By about 11 tons, yes. I have to say that SQ is what really swung the pendulum in favor of the A340, especially the A343, for which 218 frames were delivered. The MD11 could not perform the missions that the A343 could. SQ actually canceled an MD11 order over that. It needed the A343 for destinations like CDG and MXP.

Aptivaboy wrote:It really was a cash crunch problem. McD was perpetually short of ready cash. Other than the F-4 Phantom program and some other military programs, the McDonnell side of things wasn't nearly as large and profitable as the other big aerospace players. The same could be said for Douglas, which while legendary for its designs, just wasn't large enough to capture the kind of profits and market share that Boeing could. When the two merged, many in in the industry openly wondered how a merger of two smaller, cash-poor contractors could ever really compete. I may be overstating things a bit, and if so I apologize, but historically that's more or less true.
So... When the MD-11 came around, McD didn't have the cash to either significantly redesign the DC-10, especially its wing, nor to design a totally new airplane. As a result, a lot of the finer points were missed and the MD-11 never really met its design criteria. However, the 777 and the A330/340 could and did, and both proved quite capable and adaptable, especially the 777. As a result, airlines either didn't buy further MD-11s, or rid themselves of the type fairly quickly; American comes to mind. American was VERY upset with the missed performance goals and said so quite publicly, at times. N1750B was delivered to AA in May of 1991, and was gone by February of 1997, not even six years.
Another issue had to do with the type being a trijet, and the newer twins like the 777 and the A330 were simply more efficient, and didn't entail the jungle gym necessary to service that tall tail mounted engine. Two newer, modern engines were simply more fuel efficient than three, and the size of the center engine housing meant that only certain engines could ever fit there, so they couldn't reengine it, even if someone wanted to. But, you can hang any number of engines of various sizes off of the wings of the 777 and A330/340, which gives airlines a lot of flexibility.
Anyway, its a shame the McD never really made the MD-11 what it could have been. With more cash and perhaps a partnership with Airbus, the MD-11 or something to follow after the DC-10 would have been quite remarkable to see.

The fuselage slope behind the wing.

This is it. The MD11 was heavier and failed to meet the promised performance. By the time the PIPs came in, airlines had either canceled orders (like SQ) or lost faith and dumped them early (like AA).

It was the A330 that killed the A340, by being more capable as later versions were made the A330-300 could do all but the longest A340-300 missions. Sadly the A340-500/600 sold poorly. Airbus got their revenge on the 77W with the A350-1000, the new 77W.

The A345 was a bad answer to the B77L (with the A346 being an answer to the B77W). It took until the A349/A35K to provide a worthy competitor.
I have to wonder what if the A345 was available as a freighter from the start.
DeltaMD95 wrote:The reason is simple. It’s because the MD-11 was offered for only 7 years after EIS (1991-98) and the A340 was offered for 28 years after EIS (1993-2011). Also add European nationalism that guaranteed the A340 orders from the likes of LH, AF, IB, etc.
Despite a production run that was twice as long, today a higher percentage of MD-11s are active than A340s (55% vs 33%), from their respective production runs.

I am not sure the early A330-300 was "deliberately handicapped". One have to remember that it's 1993 we are talking about. The A330-300 is a large aircraft. It's a lot larger than the 767. The engine technology at that time has its limitation. If the A330-300 could have been made to fly long range at that time, Airbus would not need to come up with the shortened A330-200 in 1998 to satisfy the twin-engine long range market. They could have made all the MTOW increase in A330-300 at that time already. But it took them 10+ more years from there to gradually improve the A330-300 to make the A330-200 obsolete.
Also remember that the early 777-200 (i.e. the A-model) also has a range similar to the early A330-300. 777-200ER (or it was called 777-200IGW initially) came out much later. Before 777-200ER, there was no twin that can fly trans-Pacific.
Based on the development history of 777-200ER and A330-300, I would say it was a necessity back in 1993 that 3 or 4 engines are needed for a long range aircraft that carries 300+ passengers.

Commonality with the A330 wouldn't have played much of a role because the 330 initially wasn't a big success. Can't immediately think of airlines that operated both 330's and 340's in the mid '90's.
The 340 was simply the best plane in the market. Although it got overtaken pretty quickly. Perhaps Airbus didn't anticipate the ETOPS possibilities of twins soon enough.

CX for one. They were a solid A340 operator and one of the largest A330 operators.
There may be 1 or 2 others I can’t think of.
