Freighters, Maximum Load Density

Sun Jan 31, 2010 2:16 pm

The 777F and 747-8F apparently have a maximum load density of 158.6 kg/ cu. m. Does any one have this data for the other 747 freighter versions and the A330-200F?

Thanks.

747-400F: 162.3 kg/m3
747-400ERF: 161.8 kg/m3
747-400BCF: 160.5 kg/m3
A330-200F: 145.3 kg/m3

Thanks Tom. After I posted the question I realised that kg/m3 does not , by itself, provide floor loading. On reflection I guess that so long as the max density is not exceeded , the floor load is not exceeded. !  blush

That's mathmatically true, but very unlikely to happen in practice because the max density is extremely low (SG of ~0.15). Unless you're carrying stuff that's got a lot of low density packing material (think tons of packing peanuts), you're quite likely to be carrying cargo that's above max density and you just run out of weight before you run out of volume.

I would expect that this depends very much on the operator's load mix. The package operators like FX are about 120 kg/m3 which is considerably less than the typical ~ 160. So I would expect they run out of volume first.
Interesting to note that EK quote the volume capacity of their 777F at 550 m3 much less than the Boeing figure of 636 m3. Perhaps to do with their average density and/ or sector length that they fly with the type. AF quote their number at 653 m3.
