The second sentence means you will not be violated for not following their guidance alone. The FAA WILL use non guidance against you if it results or contributes to a violation. Good question. Means the same as a Advisory C. Don't forget two things. Because of the patriot act a regulation can be a law. The FAA uses the IRS for enforcement. Is it worth it anymore to fly RC? Each RC club should have it's own legal department. I foresee AOPA expanding their legal defense insurance to RC pilots.
