The UPS MD-11 into SYD comes out of HNL and operates non stop. There's no particular "base" for the airplanes. Crews are based in SDF and ANC (maybe ONT???)
The longest MD flight I've ever dispatched was LAD to IAH, around 8000NM. This was a pax configured plane and coul carry minimal payload usually (about 20,000lbs and sometimes had to be towed to the end of the runway for starting to make it)
The HNL-SYD is about 5000NM and change. Some days you can load it up pretty well, usually bulking out before hitting weight limits. The longest flight regular MD freighter flights we op are close to 6000NM and are very restricted.
Because it sucked. It was late, and when it arrived it underperformed. The MD-11 did not offer as much range as the A340, which also offered significant commonality with the A330 (though the 330 was nothing special in those days). And when the 777 showed up a few years later, the MD-11 was soundly outclassed in pretty much every respect.
Largely because nobody wants them to fly passengers. Used planes for conversion were easy to find and were relatively cheap. Also new builds freighters were offered early since the line was not that jammed with passenger planes. As far as new build widebody freighters went in those days the MD-11 was really about the only game in town for long range flights. The 747-400F wasn't built for several more years, as was the 767-300F and the A300F didn't offer the same range as the MD-11.
Why do Aerospace Engineering students have to turn things in on time?
Why the greater range with the CF6s? I'm assuming the fuel consumption is slightly better...but why, exactly?
Further, I remember reading here about 767s having better resale value if equipped with CF6s (vs. PW4060s) due to lower maintenance costs. Is the same true for the 767 in terms of fuel consumption? Further still, do MD-11s powered with CF6s have better resale value for the same reason as the 767?

Quoting Tupolev160 (Reply 10): Why did the MD-11 became so popular as a freighter while near-extinct as
Actually, the MD-11 is a popular freighter because it can loaded to its max payload weight and max volumetric capability at the same time using general cargo densities. Other freighters will reach either limit before the other.

Quoting delawareusa (Reply 16): Also the MD-11 tends to flip when landing in a crosswind. It's tail is too small. This is too large a risk for most commercial pax aircrafts, but not for freighters.
Wrong~ It doesn't "tend to flip". I've flown the jet for 12 yrs and never seen a tendency to flip. Yes you must watch side loads on the gear and don't unload the elevator in a bounce. This has been covered a bazillion times.
