Have to agree the 1.66 scalar is much more realistic BUT it's quite a change from 0.60. Where did this figure get derived?

Also been looking at the fuel flow errors and it looks to me like when they applied the flow rates to the individual gauges they didn't divide the rate by 2.

I found the area in the ...\Model\CS_B52_interior.MDL file where they handled the variables and can see where they used them but there is no divider that I can see amongst the gobbly goop eg.
(A:TURB ENG1 FUEL FLOW PPH,pounds per hour) 2 /
Obviously I do not have the ability to edit the MDL file anyway.
