The chord is the average thicknes of the wing from leading edge to trailing edge. If it is a tapering wing, just average the chord length at the tip and the root.

Thanks! The average eh? Well what if the last 5 feet of the wing start to round back? Not all the way tapered, but tapered at the tip...? Do I average it then?

I would take a best guess... or break the wing into sections and average each section's average

The real way to do it would be to add a seperate airFoil/airPt object for each section of the wing that has its own chord. area, AR, etc. This is KEY to FM success. A really crazy wing (like the taube for example) could have 3 airPts per wing! Also this could simulate wign warping or odd control surfaces, etc.

Thanks! The wing tip now has a different Chord than the rest. I averaged it in sections.
