Fine...Then regardless of what I say about myself, why have you been unable to answer all these aviation related questions? Remember, it was you who claimed to have aviation 'background' to shut down the Indians, and yet out of six questions, four you did not know and two pending.
So here they are again...
Q: What else does a flap change, other than the physical layout of the wing?
Q: In the above example of one wing that illustrate three different areas, what is the common denominator of all three areas that directly affect wing geometry design, which in consequence determine a wing's characteristics such as drag and stall speed? Hint: In the 'Reference Wing Area', you must use the underside surface, that is why the illustration have the red field intrude into the fuselage.
Should be simple enough for you, right?
