What You'll Learn
Jet bridges improve accessibility
Jet bridges, also known as jetways, are enclosed connectors that link an airport terminal to an aircraft, allowing passengers to board and disembark without being exposed to the outdoor climate. They are powered by electric motors or hydraulic systems and are equipped with sensors for safety. Jet bridges have become the standard way of embarking and disembarking passengers, offering improved accessibility and convenience.
Jet bridges enhance accessibility for passengers with reduced mobility or disabilities by providing a level pathway directly from the terminal to the aircraft door. This ensures equitable access to air travel and promotes inclusivity within the aviation industry. They also improve the overall efficiency of airport operations by streamlining the boarding and disembarkation processes, helping airlines adhere to schedules and optimise aircraft utilisation.
Prior to the introduction of jet bridges, passengers typically boarded aircraft by walking up a ground-level ramp and climbing a set of movable stairs. This method can be challenging for individuals with limited mobility or disabilities. With jet bridges, passengers no longer need to navigate stairs or specialised wheelchair lifts, making the process more accessible and comfortable.
In addition to improved accessibility, jet bridges offer protection from harsh weather conditions. They provide all-weather dry access to aircraft, ensuring passengers are not exposed to rain, snow, or extreme temperatures. This feature is particularly beneficial for individuals who may be more vulnerable to the elements, such as the elderly or those with medical conditions.
Furthermore, jet bridges enhance the security of terminal operations. They provide a controlled and enclosed environment for passenger movement, reducing potential security risks associated with outdoor boarding processes. The use of jet bridges also allows for efficient ground handling operations, streamlining the flow of passengers and improving overall airport efficiency.
While jet bridges offer significant advantages in terms of accessibility and efficiency, they also have some limitations. Jet bridges occupy more space compared to remote stands that do not utilise them. As a result, airports often charge higher fees for the use of jet bridges, which may deter low-cost airlines from using them. However, the benefits of jet bridges in terms of accessibility and passenger experience cannot be overlooked, and they continue to be a crucial component of modern airport infrastructure.

Jet bridge safety
Jet bridges, also known as passenger loading bridges, are enclosed connectors that extend from an airport terminal to an aircraft. They are used to facilitate the comfortable and convenient movement of passengers to and from an aircraft. Jet bridges are particularly beneficial for individuals with disabilities or mobility impairments, as they eliminate the need for climbing stairs or using specialised lifts.
Given the crucial role of jet bridges in ensuring safe and efficient passenger movement, rigorous safety protocols and training procedures are in place for their operation. One key safety aspect is the preflight inspection of the jet bridge and the ramp. This inspection involves a thorough walk-around to identify any potential issues, such as broken components or dislodged sensors. Additionally, it is essential to ensure that there are no sharp objects or foreign object debris (FOD) in the path of the jet bridge to prevent damage to its tires.
Another vital safety consideration is the positioning of the jet bridge. Jet bridges must remain in their designated home position, marked by ground markings, until the arrival of the aircraft. This safety zone is critical in preventing collisions between the jet bridge and the approaching aircraft. Modern technology, such as electronic safety interlocks, further enhances this aspect by enabling communication between the jet bridge and the aircraft to ensure safe operations.
The operators of jet bridges also undergo comprehensive training and certification processes. This training covers basic operations, controls, and the unique characteristics of different aircraft types. Operators develop a sense of jet bridge handling, similar to how a driver gains road sense. Regular refresher trainings and annual certifications help operators stay updated with any equipment upgrades or changes. Additionally, the health, fitness, and medical conditions of operators are taken into account, as work fatigue can impact their alertness and focus during jet bridge operations.
Furthermore, jet bridges are equipped with various technological features to enhance safety. These include sensors that detect and prevent collisions with aircraft, as well as a "dead man's switch" in the joystick that disables bridge movement if the operator releases pressure. The use of a wingman during jet bridge operations provides additional safety by guiding the operator and monitoring the process from the ramp.
In conclusion, jet bridge safety is of paramount importance in the aviation industry. Through a combination of rigorous training for operators, stringent safety protocols, and the implementation of advanced technological features, the safe and efficient movement of passengers between the airport terminal and aircraft is ensured.

Jet bridge design and construction
Jet bridges, also known as passenger boarding bridges, are enclosed connectors that extend from an airport terminal gate to an airplane, allowing passengers to board and disembark safely and efficiently without being exposed to harsh weather. They are typically made of steel or aluminium and are powered by electric motors or hydraulic systems. The design and construction of jet bridges involve several key components and considerations:
Design and Functionality:
Jet bridges are designed to provide a safe and convenient way for passengers to board and disembark aircraft. They are usually fixed at the terminal end, with the ability to pivot to the sides and extend outwards to meet the aircraft. The jet bridge may also need to be lowered or raised to align with the aircraft door. Some jet bridges are anchored in the middle and movable at both ends to connect with the departures or arrivals level of the terminal building.
Major Components:
A jet bridge has five main components: the rotunda, telescopic tunnels, elevation system, cabin, and traction system. The rotunda acts as the interface between the airport building and the jet bridge, providing a strong foundation for the remaining parts. Telescopic tunnels are supported by the rotunda on one side and the elevation system on the other, allowing for vertical adjustments. The cabin is the enclosed, spacious, and bright interior of the jet bridge, designed to enhance passenger comfort and flow. The traction system enables the movement and adjustments of the jet bridge.
Safety and Accessibility:
Jet bridges are equipped with various safety features, including multiple sensors and cameras for automatic alignment and docking. They also have leveling devices to facilitate a smooth transition from the aircraft floor to the jet bridge floor, improving accessibility for passengers with disabilities or mobility impairments.
Customisation and Flexibility:
Jet bridge manufacturers offer custom-built solutions to meet the specific requirements of different airports and aircraft. This includes made-to-measure designs, various tunnel materials (glass or steel), and different types of elevation systems (hydraulic or electromechanical). Jet bridges can also accommodate changing aircraft and terminal configurations, ensuring logistical flexibility.
Construction and Materials:
Jet bridges are typically constructed using high-quality steel or aluminium. The use of advanced manufacturing techniques, such as welding to certified standards, ensures the structural integrity and longevity of the jet bridge. The materials and design of the jet bridge also consider thermal needs and weather resistance to prevent water accumulation, leaks, and corrosion.
