Revision test #2

DMC created the topic: Revision test #2

Hi all,

In the second revision test, question 7, it gives an Echo with gross weight 2550kg and moment index of 620. It asks what the least weight is that can be added to place the aeroplane withing CoG limits, however if I calculate (2550-2360)*0.27 + 2400, it gives an answer for the forward limit being 2419, placing the plane within both forward and aft limits (the CoG is at 2431mm)

My question is, how come when I plot 2550kg and moment index of 620 on the CoG graph, it does not fit in the envelope??

I hope I'm not missing something too fundamental :(

Thanks a lot
