I have not done all my homework on this but again, thank you for the input on this. What made me ask this question is f.o.d… Think about it, if you work on the ramp you see load sheets, daily schedules, and other random trash onboard aircraft. Now lets say that random trash adds up to a simple pound…or so. How much additional fuel is the aircraft going to burn every time it has a rotation.
In this day and age it pays to keep any and all undue payload off an aircraft no matter how small.
So going back to the top, if there is just 1 lb. per aircraft and you have 600+ aircraft, that is 600 pounds extra weight being carried in your system. If it takes 1 gallon of JetA to carry that pound now you are talking about undue $ spent.
