Stealth Pilot a écrit:

it is Desgrandchamps book about the design of light aircraft.

You may have electronic copy of this book.

Well, I tried to make a start, but disappointment was almost immediate:
the PDF is incomplete, actually it even lacks TABLE 1 which is the basis
of all further formulae and calculations.

I privately received another version, in two pdf-parts, with exactly the
same pages missing - too bad.

Would anyone have the original book, or a pointer to a library that has
it? One of France's excellent aviation museums, perhaps? Or the RSA?
