At the time of the FAA making up this framework, I would venture more than half of commercial pilots had some military aviation background. It is so close to Boyd's model, I would think that a research might find that it was highly inspired if not a direct descendant of Boyd's work.

However, Body was real time combat, and I think the FAA is supposed to be beyond a cockpit crisis, and maybe another framework is Demings PDCA framework, which looks like you could roughly match the pieces.
