I've seen a number of questions relating to basic design and I've had many of those questions myself over the years - and still have many questions.
Suggestions about obtaining the many textbooks can't be overrated, however I suspect that much of the maths is difficult for many to manage - including myself, I've had to struggle!
So it's with interest when I find some very simple and concrete method to check my own assumptions on my own calculations.
Duncan 'RTFM' on this discussion group has on his web site, the Roncz Spread sheets and the Raymer spreadsheets (SS).
I've discovered another lot of (SS) done by neal Williford for Sport Aviation in 2000/2001 and can be found at aircrafthomebuilders.com under the heading of 'Software and Design'.
Now these (SS) don't have it all, but by interrogating the Excel programs available, you will be able to trace the calculations and where/ what they come from. Nothing however replaces a good understanding of the maths.
I suspect that after using perhaps 3 lots of (SS) and getting the same/similar answer, you might start to feel comfortable about your performance expectations. These (SS) will give many a novice a better understanding about how the process works and the many and varied performance parameters.
Hope it helps. Perhaps other will also contribute to the discussion.
