Please correct discrepancies in the subject PreVABS example.
The example write-up says, “There are two webs, whose right boundaries are at the 20% and 50% location of the chord”. But, it also refers to [CHEN2010] which defines web centerlines at 15% and 50%, which appears to be how PreVABS example files are actually defined. Figures 32 and 33 are shown below, aligned and scaled chordwise, with orange dotted lines indicating the LE, TE and web locations. The upper figure (32) appears to agree with the example write-up.
