Which of the following is a major consequence of not adhering to airside protocols?

The major consequence of not adhering to airside protocols is the potential for accidents and fines. Airside protocols are established to ensure safety and security in areas where aircraft operate and where ground vehicles interact with airport operations. When these protocols are ignored, it increases the likelihood of collisions or near-misses between vehicles and aircraft, as well as incidents that could endanger personnel on the tarmac.

In addition to the safety risks, violations of airside protocols can lead to regulatory consequences, including hefty fines from aviation authorities. These penalties serve as a deterrent to ensure compliance and can impact the operating status of the vehicles and personnel involved.

While other choices like increased job opportunities, improved airport efficiency, and reduced costs may be desirable outcomes, they do not directly relate to the repercussions of failing to follow established airside procedures. Ignoring these protocols fundamentally puts safety at risk, which is the primary concern in airside operations.
