Hi Captain Kevin and Virtuali, thanks for your replies,
By a system of trial and error, as I do not knot know the significance of all the figures in the line, I have arrived at a working arrangement.
The line looks like this .... station_load.0=20000,000, 0.000, 0.000, 0.000
This gives me a passenger load of 91.
I suspect that all the other zero's must put the load at, or near to, the centre of gravity.
Best regards and thanks,
Martin.
