With all due respect Joe, there are multiple legal arguments that actually place U$hPa's Rating System/Procedures into the public domain. One would be that the US Copyright Office informed me (and has information on their web site) that Systems and Procedures are not copyrightable. Another is the Merger Doctrine, which states that one entity can't claim ownership of something that, while somewhat different, is also a similar yet necessary for another entity to do business. If you look it up you'll find a better explanation than the one I just gave.
And if some entity does hold a (non-system/non-procedural) copyright on something, then Fair Use is allowed connected with teaching/educational purposes.
I would also mention that a good way to compare something that is copyrightable and something that isn't is to take a look at Peter Cheney's "Hang Gliding For The Beginner Pilot". I have a copy and compared to the U$hPa's Rating SYSTEM, Cheney's book exemplifies and demonstrates the difference between a creative work (able to be copyrighted) and one that is simply a described "system" and/or set of "procedures" (not legally copyrightable).
One thing I would mention is that what the U$hPa has called its corporate guidelines for doing business, it's
Standard Operating PROCEDURES. So, it might be said that all the procedures that the U$hPa has published are (contrary to what that document indicates) not copyrightable - including the "Rating System" within that document.
