You may remember
my previous criticism of the AOPA Air Safety Foundation for a bit of misinformation in its online course on Mountain Flying.
I am happy to report that the course has been overhauled and
republished, with a much more accurate portrayal of mountain waves. We've gone from "Beware of these clouds" to correctly identifying lenticular clouds as marking smooth air that can be "good for gliders:"

OK, so the rotors are still turning the wrong way in this illustration, but that is minor compared with all the improvements over the previous version.
AOPA gets full credit for going to the trouble and expense of improving this online course. If only the FAA were as conscientious about the accuracy of their published materials.
By the way, AOPA has recently increased the amount of attention paid to the communities of pilots who don't fly airplanes. They have published excellent pieces on
proficiency and
cross-training, and have regular
blog posts about soaring. We can thank SSA members Chris O'Callaghan, Val Paget, and Bill Daniels for this.
