2 to 5 hrs sectors, 35 to 40 tons, we need lots of volume, south america. It would be imposible to use a TC aircraft here in south america. A300F mant can be done by TACA, Aeroman, so costs inicially are low. And initially the A300F looks like a versatile aircraft.
DC10 is ideal, I love it and study the aircraft a lot, but is to big for start up. The idea is to have dc10 in the future, but not for start up, to much cost. All the mant is on the north i think and It will be very dificult to have 65 tons of cargo from the start up. I was looking also the DC10-10F wich has less cargo, lots of volume, and it will be easy to operate DC10-10F and DC10-30F in a future, but all the DC10-10F have a lots of hs on their back, 80000 or more, and I dont have the fuel burn, payload, mant cost for that aircraft, and is a little to big for start up, but is not a bad idea, same crew for 10F and 30F, same mant plan, etc.
