Thank you so much. Now I understand.
Could you please help me with this one please? I made it but my answer is slightly more than it should be just wonder if I did something wrong.
The question is.
an aeroplane has a zero fuel mass 47.800 kg and a performance limited TOM of 62.000 kg. The distances of the leading edge and trailing edge of the MAC from the datum are 16 m and 19.5 m. What quantity of fuel in imperial gallons must be taken up to move the CG from 30% MAC to 23%MAC if the tank arm is 16 m aft of the datum and the fuel SG is 0.72?
thank you.
