Tag created the topic: Weight to shift or add formula
Hi, I'm confused with the weight to shift or add formula -Weight to shift or add = (ZFW x (change in CofG)) / Distance between arms-
(ref: Q°50 PPLA#2 )
I'm ok with the formula but I often get the wrong answer to this type of question.
For example (loading charlie) :
-BEW index unit 19579
What's the max weight in KG that may be carried in row 2 at takeoff?
With the formula above I find 144kg. Correct answer is B. There is obviously something I do wrong, but what is it ???

I'm not sure what your working is. It seems that you have used the weight to shift formula when the question is asking for the weight to add to row 2. Also, remember that the aircraft must be in balance at ZFW as well as at take-off.
