ATPL Mass & Balance recollection

.. you mean ... ground schools teach this nonsense ?


I have a copy of this formula at home (taken from an A330 GOM/AHM),

.. you mean ... other people do it this way as well ?

Absolutely mind blowing.

Now, I can see no reason for taking a simple equation (surely we agree that the standard %MAC equation is simple ?) and turning it into an unwieldy complicated thing when there is no apparent advantage gained for anyone.

The evidence of the errors which have come to light in this thread's discussions should be adequate indication of the undesirability of this needlessly complex way to do something which, inherently, is very simple ....

Perhaps someone can offer an explanation as to the philosophy behind this apparently strange phenomenon ? Or is it just a case that Aussies like to take the easy way ... ?
