Default MacCready theory in wave



Enjoy! Let me know if you see bugs.

Good article, John. Now, if I was proof-reading it, I'd suggest adding a few more axis labels to the plots and the legends. On P1, the sentence "Going upwind to wave lift is just like flying through no wind to thermal lift.." should be changed to "Going upwind in wave lift is just like flying through no wind in thermal lift...". My first reading of that sentence was that the pilot was pushing upwind in zero lift (or the frequent heavy sink) to get to the wave band, whereas your analysis assumes that the pilot is in wave lift constantly.

My 2c.
