Don't use this profile without correcting the fuel arm - it is 10" out!

My Cessna POH gives useable fuel of 135 lbs and moment arm of 5700 lb-ins.  This equates to a moment arm of 42.2 ins.


What data are you using?

My apologies, your second profile seems to be correct on the fuel arm (though I haven't checked any other figures).
I have checked several different years of C150/152s and several W&B excel sheets available form various sources.
It seems that some of the excel sheets have erroneously used the fuel arm as 40" (instead of the correct 42" or 42.2").
I believe this is because the weighing instructions in the POH show the arm as 40" for the UNUSABLE fuel. In the absence of any other obvious figure this has been wrongly taken as the arm for the full fuel load.

Thanks for your response.  These forums are a great place to share information with other like minded people.  I don't know where my original figure of 32.2 came from!  I cant find any data or charts to justify that figure.  I presume that it was a typo, which would have gone undiscovered without your vigilance.  Many thanks.
