An alternative option:
I learned all the W&B formulae and passed all of the CPL exams. I felt I understood it , too!
H O W E V E R - what really cemented it into my little brain was a few years ago watching an aeroplane going through a new weight and balance. (I'd seen it done a few times but never really took an active interest...)
Seeing the a/c jacked, levelled and weighed - understanding where the datum was, watching all the measurements being done and the primary school maths required............... chalk lines on the hangar floor, tape measures and multiplying and dividing big numbers!!......
well it all became so obvious!
I would recommend anyone to go and see this happening as it might just all "click" as it did for me!
