Before a passenger ever steps onto an airplane, an entire mechanical system has to move into position.

A jet bridge extends from the airport terminal.

It rotates.

It telescopes.

It rises and lowers.

And finally, it connects precisely with an aircraft door.

In Engineering Insights S2 E83, we explore the engineering behind airport jet bridge systems and the technology that makes boarding and deplaning thousands of passengers possible every day.

We examine how jet bridges are designed to move safely around aircraft while accommodating different aircraft sizes, door heights, terminal configurations, and changing ramp conditions.

We explore the mechanical systems that allow a bridge to extend and retract, the drive mechanisms that move it across the apron, the lifting systems that adjust ...
