A second example is a wing with a leading edge extension, similar to many modern fighter planes, such as the F-16. Each wing panel, left and right, is made up of two segments defined by three chords. Note that we only define the exposed wing, that not covered by the body. In the previous example, the wing started at x=0, but this is not necessary. In fact, when laying out an airplane, one rarely sets the leading edge of the wing root chord at x=0.
The input for the right wing is:
&chord y=200, xle=100, chord=1000/ &chord y=400, xle=500, chord=600/ &chord y=1000, xle=900, chord=200/
