1) I suppose someone should tell Boeing and my company that the payload is 112T. It's actually 121T.
2) My statement about the MD
-11 is not contradictory at all. The MD
-11 is used as a high volume, low weight platform. There is no nose door, so you are limited to what can fit through the side door. Where as, the 744F can take outsized cargo, such as oil drilling equipment, electrical generators and so on. When the MD
-11 was introduced there was a void in the market for that type of aircraft. For operators such as FedEx, who's primary business is small package transport, the 747 was just too big. The payload would never approach the limits thus making the economics for the 744/747 too expensive.
3) Again, the 380F is limited in it's floor loading thus limiting the ability to take outsized cargo. That coupled with the lack of a nose door will severely limit the ability of traditional cargo carriers to take outsized cargo. The outsized cargo is actually a significant portion of the business. It is extremely attractive in terms of revenue.
4) Finally, the market share of the 744F vs. the MD
-11 was influenced not by the MD
-11 being a better freighter but the fact there were so many 747-200F and Pax aircraft on the market. The pax airframes could be converted to a SF
for about US$25million. Therefore, the used aircraft became a very attractive alternative to both the 744F and the MD
