No, it is not. The regulation says "unless otherwise authorized," and the
45 degree entry is specifically authorized as a legal maneuver in a
document
signed by the Administrator (the AIM).


Where is that stated in the AIM? What's the purpose of promulgating a
regulation that everyone is authorized to deviate from?



The AIM may not be regulatory,


There's no "may" about it, the AIM itself says it's not regulatory.



but following the procedures in the AIM provides a safe harbor and use of
those procedures is to be presumed by the FAA to be in compliance with all
federal regulations.


What do you base that on?
