Hi Brad,
It’s important to note that the Know Before You Fly Campaign is not a change to the National Model Aircraft Safety Code and AMA’s safety program. The KBYF campaign is intended to provide safety guidance for the emerging community of thousands of non AMA members and non-modelers engaged in a new technology that is a bit different than the more traditional forms of model aviation.
Model aircraft enthusiasts operating under the “Special Rule for Model Aircraft” are still governed by PL 112-95, Sec 336 and AMA’s safety programming. AMA members should continue to operate in accordance with the AMA Safety Code and related safety documents.”
For AMA members... AMA's guidelines are to:
Not interfere with manned aircraft
Remain well clear of manned aircraft
See & Avoid all aircraft and obstacles in accordance with Doc 540-D
And, remain at or below 400' AGL when within 3 miles of the airport.
Hope this helps,
Rich Hanson
