A system, not just aircraft
Aviation is the design, production and operation of heavier-than-air aircraft, plus everything that makes flight possible: airports, air traffic control, meteorology, maintenance, regulation and training. A single scheduled flight touches dozens of these functions before the doors even close.
The three big sectors
Commercial air transport moves passengers and cargo for hire. General aviation covers everything else civil — flight training, private flying, agricultural work, air ambulance. Military aviation operates under separate rules and airspace arrangements. Most of what you will learn here applies to civil flying under ICAO-derived rules.
Who sets the rules
ICAO, a UN agency, publishes standards and recommended practices. National authorities such as the FAA, EASA or CAA turn those into enforceable regulations. Airlines then add their own operations manuals, which are usually stricter than the law.
Key points
- Aviation is a layered system: aircraft, infrastructure, people, rules.
- ICAO standardises; national authorities regulate; operators implement.
- General aviation accounts for the majority of aircraft movements worldwide.
