Hi Mark

For several hours I have been gathering (and converted!) all necessary 707-300 data for FSC9 - Not easy, because the information is diverging depending on where you look! A few data I simply couldn't find, so I had to guess!
However there's one aspect that is missing in your schedule - item no.11 and I can't figure out what it could be..?
In the example with the MD11 Cargo, it is present with the value '460'.
Properly some speed value thing...
