With the big push to convert Triple Seven's to freighters, especially the -300ER, will UPS finally join the club? Living in Louisville, I certainly hope so!! I have never heard the roar of the GE90-115B in person. That, plus it's economics render the MD-11 (an aircraft I love) virtually unacceptable in today's business world. I wish Mammoth luck in their efforts.
UPS and FX are adding some LH MD-11s to their fleets. They wouldn't do so if it wasn't still a good freighter.
The UPS MD11 fleet, will last at least 5 more years, before the oldest are retired first.
The MD11 can be used at domestic short routes (plenty of cycles left), fitting at the parking position of the short haul fleet and occasionally can be used at the international routes, when needed.
The acquisition cost of the last 5 MD11F's was relative low, the residual book value of most MD11's is even lower, or even zero.
The MD11 maintenance cost are some what higher (one extra engine), but the MD11 aging aircraft costs (AD's) are one of the lowest, compared to other aircraft types.
The only drawback could be a massive rise in fuel costs, but at the current MD11 UPS network (90% shorthaul stretches) the extra fuel consumption will be easy offset by the low A-M-I costs..
