Definition
The transportation by aircraft of people, mail, or goods for hire or as part of a business activity, including any operation of aircraft that affects or is connected to such transportation. In U.S. law, the term forms the legal basis for federal regulation of civil aviation.
Plain English
Using aircraft as part of a business — to carry passengers, mail, or cargo for payment, or to support that kind of operation.
Context Anchor
Seen in FAA history and regulation discussions, especially when describing how early air mail routes helped build the U.S. aviation industry.
Derivation
‘Commerce’ comes from the Latin commercium, meaning ‘trade’ or ‘exchange of goods.’ ‘Air commerce’ simply applies that idea to aircraft — trade and transport carried out by air.
Why Pilots Care
Air commerce is the legal hook that allowed the federal government to regulate civil aviation in the first place. The 1926 Air Commerce Act gave rise to pilot certification, aircraft registration, and the airway system — the foundation of nearly every rule pilots fly under today.
Intuition Check
Do not read air commerce as simply “anything involving airplanes.” Here it means aviation used for trade, transport, mail, or business under federal aviation rules.
Example Sentence 1
