I read the initial ruling that came out a couple years ago, and the definition of a tethered UAS as worded could include our cable operated control line aircraft. I've been told by various AMA members and the official statements by the AMA that it does not include C/L. What concerns me, is not what they claim it is being interpreted as, but what in reality it really says.
Having worked intimately with contractual verbiage, what you hold a contractor to is what is actually written. They are bound by what they signed up for.
That is the only thing we have going for us right now- the written rule describes a UAS very specifically, it includes the use of a "ground control station" They were attempting to describe a typical quadcopter drone, but the same definition happened to include traditional LOS RC, and there was no real effort to distinguish it. FF, for sure, does not have anything resembling a "ground control station" and is therefore not a UAS. It is an extreme stretch to consider a control handle a "ground control station", so it almost certainly is not a UAS, either. I think that part of it is OK, and that is the same part that the AMA bases their statements on.
The problem I and many other people have with it is that there are documents and pamphlets summarizing the situation for others, and in those, i have yet to see a single attempt to clearly make that distinction, they say that if it is more than 5.5 ounces and goes in the air, it is regulated. Meaning, you could probably win a court case over it, but that means you have already had to go to court, and that alone is prohibitive.
