# airport (transport)

large building where people board and leave a vehicle that travels through air

- Computed level: L17 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: structure  ·  Arena: airports

## Emergence
**Emerges from:** [building](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-building.structure), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [air](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-air.material), [board](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-board.material), [car](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-car.transport), [large](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-large.size), [leave](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-leave.movement), [people](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-people.social), [travel](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-travel.movement)

**Through:** building.structure and space.extent are arranged with air.material and car.transport to enable people to board and travel through air

**Novel properties:**
- aerial transit hub
- structured passenger flow
- takeoff and landing access

## Examples
- Beijing Daxing International Airport handled 34.1 million passengers in 2023 while expanding its automated boarding system. *(transport)*
- The International Space Station maintains orbit through periodic reboosts from attached thrusters. *(space)*
- Changi Airport in Singapore uses real-time sensor networks to manage passenger flow across Terminal 3. *(computing)*
