What is a common legal requirement for a contractor working at an airport?

A common legal requirement for a contractor working at an airport is to enter into a contract with the City. This contract typically outlines the terms and conditions of the contractor's operation within the airport, including adherence to safety regulations, security protocols, and operational guidelines tailored to managing the unique environment of an airport. Such contracts are essential in ensuring that all parties are aware of their responsibilities and legal obligations, and help maintain a safe and efficient airport operation for both workers and passengers.

While the other options may involve legitimate considerations for contractors, they do not represent a universal or legally mandated requirement expected of contractors in an airport setting. For instance, obtaining a flight license pertains to pilots rather than contractors, possessing only a business insurance policy may not cover all the legal obligations of operating at an airport, and hiring airport security personnel would typically be part of compliance measures rather than a contractual requirement.
