It seems that there are conversion programmes under way or being planned for virtually every jet type except the A340-300. As the 343 is likely to be superseded by the A350, 787, 772ER etc in pax service and values are already in serious decline, it would seem to be a good candidate freight conversion. It has the same cross section as the A300 so I assume can load standard ULDs and ought to have the payload range to finally see of the remaining DC8s, 707s and maybe replace DC10Fs etc but, despite all this, I've never seen any reference to the possibility. Is there something about the A343 and/or its performance that precludes its success as a freighter?
