Definition
In aviation, regulations are the legally binding rules issued by a government authority that govern how aircraft are operated, maintained, certified, and flown. In the United States, the primary set is the Federal Aviation Regulations (FARs), found in Title 14 of the Code of Federal Regulations (14 CFR), and they carry the force of law.
Plain English
Regulations are the official rules pilots must follow. They are not suggestions or best practices — they are law, and breaking them can result in fines, suspension of a pilot certificate, or worse.
Context Anchor
Seen throughout FAA handbooks, training materials, checklists, and flight planning discussions when the text explains what a pilot must or must not do.
Derivation
From Latin 'regula', meaning 'a straight stick' or 'rule' — the same root that gives us 'ruler'. The idea is a fixed standard that everyone is measured against. In aviation, regulations are the fixed standards every pilot is held to.
Why Pilots Care
Compliance with regulations determines whether a flight is legal; violations can result in certificate suspension or revocation.
Intuition Check
Do not read regulations as helpful tips or general advice. In aviation, regulations are legal rules that must be followed unless a specific exception applies.
Example Sentence 1
Before the flight, she reviewed the regulations covering instrument currency to make sure she was legal to act as pilot in command.
Example Sentence 2
The regulations require that a pilot hold an instrument rating before flying in IMC without visual reference to the ground.
