Depends on how the question and the associated data is presented. Static data is a major part of the flight test program. The data is summarised an...
First, while I have some engineering background with helos, I don't consider myself to be an expert in any shape or form .... However, you might l...

Now, that's a fairly broad-brush question and not one for which there are simple answers. Perhaps you might give us a little more information as to ...
Better still - and it probably will help others - why not do a couple of examples and then post a scan of the charts with commentary. Such might...
Did the question provide a CG/moment/IU ?
One can divert in one direction .. or, indeed, in the opposite direction ? Therein lies the confusion.
Your concern says, very clearly, that the confusion relates to what fuel SG values you are using. Keep in mind that the old "standard" SGs of 0....
Following on from my earlier comments. You now have the answer as to how to approach the question. However, it is worth including a comment a...
Ah hah ! Now I am in the picture. Afraid you are using the wrong chart. Q8 relates only to the takeoff chart and has naught to do with the climb ...
Unfortunately, I don't have any of the paperwork to which you are referring so I'm a little bit wading about in the swamp, here. I had presumed that ...
