Taken altogether, it's a noble campaign for clarity in the face of a confusing mishmash of drone law. But it's a clarity that comes from suggesting new pilots should defer to the government's interpretation of what started as voluntary guidelines, rather than navigate and interpret on their own the murky laws that exist presently. Know Before You Fly, the site supporting the campaign, has a page offering three sets of new guidelines: one for casual users, one for business users, and one for public entities. For recreational users, many of these rules are old, having first appeared as voluntary guidelines in an FAA 1981 Advisory Circular on model airplane use. Those rules, in turn, were modified somewhat by the 2012 FAA reauthorization act, but as drones move from a niche hobby to a more common toy, the FAA has tried to cancel the 1981 memo.
