In an FAA document (8083-16B) in Special Use Airspace section it says:
Prohibited and restricted areas are regulatory special use airspace and
are established in 14 CFR Part 73 through the rulemaking
process. Warning areas, MOAs, alert areas, and CFAs are
non-regulatory special use airspace.
What does regulatory and non-regulatory means in this context and what are the implications for daily operations?
