I see nothing in the FAA regulations and have heard of nothing that allows a recreational pilot to pick and choose which particular guidelines from their chosen CBO to abide by or ignore. The recreational pilot using XYZ's guidelines couldn't continue to fly using XYZ's guidelines without the altitude limit.
I think I see where the confusion is.
Congress and regulating agencies are not unlimited in what they can put into law or regulation (as I know you well know
![Slightly smiling face :slight_smile: 🙂](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)
). The Constitution, as well as statute law, prescribes boundaries around the authority the US government can exercise.
An obvious trivial example, the FAA can't prohibit being Catholic as a requirement to fly recreationally.
They can't get around this by outsourcing the policy-making to a private third party. So, if the AMA were to add "no Catholics" to their safety guidelines, it wouldn't be necessary for you to be able to find something in the FAA regulations to choose to ignore this guideline. You know you can ignore it because it conflicts with existing law (in this case the Constitution).
So CBOs can't just make ANY guideline. What governs what they can do?
We've been discussing it. As specified in 44809, these guidelines must be developed in partnership with and approved by the FAA.
Are there limits on what the FAA can approve? Yes, of course. They can only approve guidelines consistent with existing regulation, and nothing beyond existing regulation. To allow otherwise would usurp Congress' legislative authority, and would be a way for the Executive Branch to go around Congress and make law they refuse to pass.
It's been tried before, many times, as recently as the current administration, and gets shot down every time.
The open-ended nature of the CBO clause in 44809 doesn't create an unlimited power. In regulation, much is presumed, covered in other parts of the Federal CFR. So just because you don't find explicit mention that some provision is limited to the constraints of sibling regulation doesn't mean those limits are absent. All agencies'
specific regulation is presumed to be consistent with the entire CFR, without stating so. Conflict and inconstency still happens all the time, and is how citizens easily win in court against the Fed.
