Hi,I am new here and still trying the trial version.
I am struggling with the weight and balance calculation in skydemon hope someone can help me.
I have the following w&b data for the cessna 150
Empty mass            1175 lbs - arm 32,5"   --> moment 38,18
Pilot + Passenger     320 lbs -  arm 39"      --> moment 12,48
Fuel  9 usg = 54 lbs   54 lbs -  arm 40"     ---> moment  2,16
     totals:  1549 lbs     moment: 52,82
When I input these data in aircraft properties skydemon says  1548,9 lbs (this is correct) and moment arm is 34,10 not correct.
What am I doing wrong?
regards
