Shalom and greetings,
I have questions about the two planes mentioned in the subject heading please.
Am I correct that DC-10-40D stands for domestic and DC-10-40I stands for international?
What is the minimum runway distance for take off and for landing for DC-10-40D using full passenger load, full luggage load, and enough fuel load for 30 minute flight (300 nautical miles) in nice summer weather please?
You mean you found the chart confusing? It may seem too technical but it's in fact fairly easy, top chart it take-off runway requirements for a DC-10-40, with JT9D-59A engines, on a standard day (ISA parameters), bottom chart is for hot operations (35°C +) as this was your case. Then what's left is match the runway altitude ( thick horizontal lines) with the take-off weight (vertical lines) and read the length necessary, in thousands of metres, on the scale at the far right, or thousands of feet on opposite end. Don't give up just yet. ( >-< )``

Ahhhhhhh ahhhhhhhhh ahhhhhhhh ahhhhhhhh
this is getting better and now I can understand!!!!
Thanks a zillion for your kind and patient assistance!! It is much appreciated!!
Now I have to figure out exact total weight of DC-30-40D or -40I using full passenger load, full luggage load, and enough fuel load for 30 minute flight (300 nautical miles)and then read that chart!!
looks like that DC-30-40D or -40I can handle 6,500 ft runway based on my desired load mentioned above and using your chart. I think I would pick DC-30-40D since it does not have center landing wheels meaning less weight.
Unless you would like to correct me on 6,500 ft runway take off.
Let's see, assuming you take a JAL DC-10 Domestic...
JAL had their DC-10-40D on a high density configuration of 318 seats.
assuming a standardized passenger weight of 75 kg, and 20 kg for their luggage we get 30.210 kg.
The aircraft's operating empty weight is 159.187 kg so we compute that.
A common domestic route these aircraft were deployed is HND-FUK around 500 nmi long.
Fuel necessary for the 1 and a half hour flight plus an hour of contingency around 20.500 kg.
Now we do simple maths: 159.187+34.210+20.500 gives us a TOW of 209.897 kg.
Finally with our weights accounted for we look at the chart, HND is practically at sea level so we'll use that line, match with our TOW line we can assume it can take-off just fine from a 6.500 ft runway,even fully laden on a hot summer day.
