What You'll Learn
PBBs are movable, elevated walkways
A Passenger Boarding Bridge (PBB) is a movable, elevated walkway that connects an airport terminal gate to an aircraft. PBBs allow passengers to board and disembark efficiently, safely and comfortably, without having to use stairs or walk on the apron. They are also known as air bridges, jet bridges, jetways or sky bridges.
PBBs are typically connected to the aircraft door via a tunnel or flexible connector, providing a sealed, climate-controlled passage between the terminal and the aircraft. They are height-adjustable to accommodate different types and sizes of aircraft. PBBs can be retracted and moved out of the aircraft safety zone during arrival and departure. Once the aircraft is secure, a trained operator manoeuvres the PBB to connect with the desired boarding door.
PBBs are usually mobile units that use an articulating mount to fasten them to the terminal at one end, while the other end is supported on powered wheels. This allows the PBB to be moved into position once the aircraft is parked. Some PBBs are anchored in the middle and are movable at both ends, allowing them to connect to either the departures or arrivals level of the terminal building.
The use of PBBs offers several advantages. Firstly, they provide all-weather dry access to aircraft, protecting passengers from harsh weather conditions. Secondly, they enhance the security of terminal operations. Additionally, PBBs can facilitate faster loading and disembarking of passengers, particularly for larger aircraft with multiple entrances. This can lead to lower airport charges, fewer delays and increased passenger throughput.

PBBs can be adjusted to fit different aircraft
Passenger Boarding Bridges (PBBs) are enclosed, elevated passageways that connect an airport terminal gate to an aircraft, allowing passengers to board and disembark without being exposed to the elements. PBBs can be fixed or movable, with the latter being more common. These movable PBBs are mobile units that use articulating mounts at one end and powered wheels at the other, with a bridge in between built as an extendable tube.
The automatic leveling system in PBBs adjusts to changes in aircraft height due to varying weights of passengers and cargo. This system maintains a safe vertical distance for boarding and deplaning, and alarms should sound if the system fails. PBB operators play a crucial role in ensuring the safe positioning of the bridge, preventing damage to the aircraft and eliminating trip hazards for passengers.
While PBBs offer benefits such as efficient passenger movement and protection from weather conditions, they also present challenges. Airports must consider the infrastructure required to support current and future technology needs, sustainability goals, and aesthetic considerations when deciding to install or refurbish PBBs.

PBBs provide all-weather dry access
Passenger Boarding Bridges (PBBs), also known as air bridges, jet bridges, jetways, or sky bridges, are enclosed, elevated passageways that connect an airport terminal gate to an aircraft. They allow passengers to board and disembark efficiently, safely, and conveniently without having to go outside or be exposed to harsh weather conditions.
The design of PBBs enables them to accommodate different aircraft types and sizes. They are typically height-adjustable and can be raised, lowered, extended, or retracted to align with varying aircraft door heights and positions. This adaptability allows PBBs to serve a wide range of aircraft, from small planes to large jets, ensuring all-weather dry access regardless of the specific aircraft characteristics.
The flexibility of PBBs extends beyond their height adjustability. Some PBBs are designed with split bridges, dividing into two passageways from a common airport terminal access point to service different doors on the same aircraft or multiple entrances on larger aircraft. This design further enhances the efficiency of passenger movement, particularly for larger aircraft with multiple boarding doors, such as the Boeing 747 and Boeing 777.
The all-weather dry access provided by PBBs also contributes to the overall security of terminal operations. By eliminating the need for outdoor boarding and protecting passengers from the elements, PBBs reduce potential weather-related hazards during the boarding and disembarkation process. Additionally, the controlled environment within the PBB facilitates better crowd management and security checks, enhancing the overall security of the airport terminal.
In summary, PBBs, with their enclosed structure and adaptability, provide all-weather dry access, ensuring a comfortable, safe, and efficient passenger experience, regardless of external weather conditions. This feature not only enhances passenger satisfaction but also contributes to the smooth and secure operation of airport terminals, making PBBs a valuable asset for modern aviation.

PBBs are also known as jet bridges
A Passenger Boarding Bridge (PBB) is an enclosed, elevated passageway that extends from an airport terminal gate to an aeroplane. PBBs are also known as jet bridges, air bridges, jetways or sky bridges. They allow passengers to board and disembark without having to go outside or be exposed to harsh weather conditions.
PBBs are typically connected to the aircraft door via a tunnel or flexible connector, providing a sealed, climate-controlled passage between the terminal and the aircraft. They can be fixed or movable, depending on the installation. For example, PBBs at Melbourne Airport's international terminal are anchored in the middle and movable at either end, allowing the terminal building-end to be raised or lowered to connect with the departures or arrivals level of the terminal building.
The jet bridge was invented by Frank Der Yuen, with the first operational "Aero-Gangplank" installed by United at Chicago's O'Hare Airport in 1958. Jet bridges provide all-weather dry access to aircraft and enhance the security of terminal operations. They are often permanently attached at one end by a pivot or rotunda to the terminal building, with the ability to swing left or right. The cabin at the end of the loading bridge can be raised, lowered, extended or retracted, and may pivot to accommodate aircraft of different sizes.
Some airports with international gates have two or three bridges for larger aircraft with multiple entrances, allowing for faster disembarking. The Airbus A380, for example, has outside access doors on both of its two passenger decks, so loading bridges can be used for each deck. This results in faster aircraft loading, leading to lower airport charges, fewer delays and increased passenger throughput.

PBBs are considered safe and convenient
PBB stands for Passenger Boarding Bridge. It is an enclosed, elevated passageway that extends from an airport terminal gate to an aeroplane. PBBs are also known as air bridges, jet bridges, jet ways, and sky bridges.
Secondly, PBBs offer protection from the elements. Passengers can board and disembark without being exposed to harsh weather conditions, such as rain, snow, or extreme temperatures. This not only enhances comfort but also reduces the risk of slips and falls on wet or icy surfaces.
Thirdly, PBBs are adjustable and versatile. They can be height-adjusted and manoeuvred to accommodate different types and sizes of aircraft. This flexibility ensures that PBBs can be used safely with various aircraft models, including those with multiple entrances. In some cases, PBBs can even be split into two passageways, each servicing a different aircraft door, facilitating faster disembarkation for larger planes.
Additionally, PBBs enhance security. By providing an enclosed and controlled environment between the terminal and the aircraft, PBBs help maintain a secure perimeter during the boarding and disembarkation process. This controlled access can deter unauthorised individuals from accessing the aircraft and improve the monitoring of passenger movements.
Furthermore, PBBs are operated by trained personnel, who ensure the safe and proper use of the bridge. The operator controls the movement of the PBB, including extending, retracting, raising, and lowering the structure to align correctly with the aircraft door. This trained operation minimises the risk of errors or accidents during the boarding and disembarking process.
