You must really want the 767 line to close before the 7E
& starts production. That's the impression I get when reading your posts regarding the 767 Tanker Program.
"Upgrading" the KC
-135 is not the answer. The airframe is already in the 30-40 year age range. Say you upgrade the avionics and cockpit so you can have a two man flight deck crew. Your basic systems and airframe are still in the 30-40 year age range. The aircraft is still going to need more maintenance and money to operate than a new-build airframe. Having an "upgraded" 60 year old aircraft is not the answer.
If for some reason the 767 Tanker is scrapped converting ex-passenger 767's is a better option than "upgrading" KC
-135's. However that would not be without it's own pitfalls. I think you are a bit over optimistic about having five hundred 767 becoming available in the next ten years. The biggest 767 operators are AA
, UAL and DAL
. Considering the financial condition of these airlines I doubt that they are going to be getting rid of them in the next ten years. Then there's the fact that operators might not want to sell their old 767 to the DOD. They might want to sell them at a higher price on the open market for conversion to freighters.
Now lets say for the sake of argument that five hundred 767's do become available in the next ten years. Not all of them are going to be CF6 equipped. Unless you are willing to spend the money on converting PW4000 767 over to the CF6 that means an entire batch of 767 you cannot use. Of those that are available you will have to take into account the number of cycles and hours on the airframes. Some of these aircraft will be up there in the number of cycles/hours they have on them. Do you want to buy aircraft that are already up there in age? Then you have to take into consideration all the minor little differences that these aircraft will have.
Considering that most of your 767 are of the -300 model and the -200 that are out there are older you are going to probable have a mixed fleet. Once again it's going to be the small differences that are going to drive up your costs. The -200 has a different dash model of the CF6 than the -300. In addition the thrust reversers on the -200 are hydraulically operated while the ones on the -300 are pneumatically operated. In other words you are going to have maintain spares for both dash models, i.e. higher costs.
So as you can see it's not as simple as "upgrading" KC
-135 or buying used 767's.
Never take financial advice from co-workers.
