Title: Root and Tip Chord Measurement
Post by: Mike Griffin on April 19, 2013, 09:38:46 PM

On a flapped stunter, do you take into account the width of the flap at the root and the width of the flap at the tip in total root and tip chord measurement?  For example if the root chord of the wing from the leading edge of the wing to the trailing edge is 10" and the flap measures 2" at the inboard end, is the total root chord 12"  and if the tip chord of the wing measure 7" and the width of the flap at the tip is 1", is the total tip chord measurement 8 inches?

Thank you

Mike

Yes.  If your trying to determine the area of the wing, The flaps are part of the wing

For why, see the same topic on SSW.

Howard, some people don't go to the other forums.

Hi Doc

I spend 99% of my time on this forum but i did post this question on SSW also and Howard did give me a good and detailed answer over there.  I usually only post here on Sparky's forum but sometimes I do post over there.

So what's keeping you from going to the effort to explain it here?

How could I explain it there if I don't go there??    Oh I guess I do go there once in a while, but you won't see many posts from me there.
