Definition
The official daily publication of the United States federal government in which federal agencies publish proposed and final rules, notices, and presidential documents. For pilots, it is the legal venue where changes to airspace designations, special use airspace, and other FAA regulations are formally announced and made effective.
Plain English
It is the government's official daily newspaper. When a federal agency wants to create, change, or cancel a rule, it has to be printed there before it counts as law.
Context Anchor
Seen when reading about how special use airspace, airspace changes, or aviation rule changes are officially announced or proposed.
Derivation
Register comes from Latin regesta, meaning 'things recorded' or 'a list of things written down.' The Federal Register is literally the federal government's official record of what it has decided.
Why Pilots Care
Pilots check it to learn about new regulations or airspace changes that directly affect flight planning and safety.
Intuition Check
Do not read Register here as a sign-in sheet or a cash register. The Federal Register is an official public record of federal government actions.
Example Sentence 1
The new restricted area boundaries took effect once they were published in the Federal Register.
Example Sentence 2
Proposed changes to special use airspace are first published in the Federal Register for public comment.
