The 400' ceiling debate has been asked amd answered by Rich Hansen of the AMA (post 747,748). To comply with PL 112-95 Sec 336 and be exempt from further FAA regulation you must follow the "programming" of a CBO. As the AMA HAS BEEN REFEREED TO AS A CBO THAT MEETS THE REGULATORY DEFINITION (
FFA Interpretation http://www.faa.gov/uas/media/model_a..._spec_rule.pdf
footnote 7 bottom of page 12). that includes the AMA Safety Code.
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,

However if you endanger the NAS at any altitude the FAA can take enforcement action. Nothing new there..................... So THERE IS NO OVERALL 400' CEILING IF YOU FOLLOW THE PROGRAMMING OF THE AMA.
Must you be a member of the AMA??????????????? Different question.
