I am a bit confused by this thread, and I thought I knew this stuff.
While I am aware of the CBO provision, my understanding is that the FARs are the controlling regulations, and outline specifically and completely the rules I must follow when flying anywhere but a FRIA or other dedicated RC field, which is controlled by a CBO.
So, for all my drone flying I've largely (actually completely, to be frank) ignored the CBO stuff, since i don't fly at RC fields.
Am I wrong in this? Can the AMA, for example, be recognized as the Santa Cruz County CBO, set a ceiling of 250', and decide where I can and can't fly? Only between 7am and 5pm?
I thought that as long as I'm not flying at a specific RC field under the auspices of a CBO, my only master was the FAA, and local state laws and LEOs.
