I'm looking for informations regarding the MTOW (Maximum Take Off Weight) of the MD-11s.
When the MD-11 production was launched, only three versions were available with their respective MTOW: Passenger - 273,366kg / 602,500lb; Combi - 276,769kg / 610,000lb ; Freighter - 276,769kg / 610,000lb.
Then, in 1991, MP launched the MD-11CF version (283,575kg / 625,000lb)
When it appeared that the aircraft had range shortfalls, the manufacturer embarked itself on a Performance Improvement Programme which lasted several years and produced at the same time some different MTOW specifications for the trijet.
For instance and AFAIK, Swissair fleet of MD-11 was composed of 16 newly delivered aircraft, perhaps with different MTOW depending of the date of delivery, but all upgraded to MD-11AH with 285,990kg / 630,500 lb MTOW; plus the four ex. LTU which had a lower MTOW.
I've found details for Varig Logistica two MD-11Fs, as well as for those of Transmile and Saudi Arabian. Regarding SV MD-11Fs, the airline's web site shows that they have a MTOW of 286,848kg / 632,500lb. I'm slightly doubtful about these numbers for a take off weight, and perhaps are they correct for a Maximum Taxi Weight...
KLM MD-11s have a MTOW of 280,320kg / 618,000lb while those of MP, now freighters only, have the highest MTOW available. Were the MD-11CF modified before being converted to cargo only aircraft ?
In other words, I'm looking to gather as much informations as possible on the MTOW specifications of all MD-11s or all fleets of MD-11s since the first delivery till now. If any of you have older editions of the JP airline fleets book, they may find on it these details. Any good informations (with references) and/or web-links where to find what I'm looking for are welcomed.
Thanks for your help.
