A jet bridge is an enclosed, movable passageway that connects an airport terminal gate directly to an aircraft, allowing passengers to board and deplane without being exposed to the elements or walking on the tarmac.
Essentially, it's a bridge on wheels that extends from the terminal to the plane's door. They are also known by several other names, including:
- Air Bridge
- Passenger Boarding Bridge (PBB)
- Jetway
- Skybridge
Key Features and Benefits:
- Weather Protection: Provides shelter from rain, snow, wind, and sun.
- Accessibility: Offers easier access for passengers with mobility issues.
- Safety: Reduces the risk of accidents on the tarmac.
- Efficiency: Speeds up the boarding and deplaning process.
- Security: Provides a more secure environment for passenger movement.
How Jet Bridges Work:
- Extension and Alignment: The jet bridge extends from the terminal and is carefully aligned with the aircraft door.
- Height Adjustment: The bridge's height is adjusted to match the aircraft door's height.
- Secure Connection: A canopy or seal creates a tight connection between the bridge and the aircraft, preventing gaps.
- Passenger Flow: Passengers can then safely walk between the terminal and the aircraft.
Types of Jet Bridges:
While designs can vary, most jet bridges fall into a few common categories:
- Apron Drive: These are the most common type. The jet bridge is supported by wheels at the aircraft end, allowing it to be driven and positioned precisely by an operator.
- Elevated: Some jet bridges are elevated on a platform, providing additional clearance and flexibility.
- Fixed: These are less common and typically used for smaller aircraft or in situations where frequent adjustments aren't necessary.
In summary, a jet bridge is a crucial piece of airport infrastructure that enhances the passenger experience by providing a safe, convenient, and weather-protected connection between the terminal and the aircraft.
