What must a vehicle equipped with a radio do at YOW?

A vehicle equipped with a radio at YOW (Ottawa Macdonald-Cartier International Airport) must communicate with air traffic control (ATC) and follow their instructions. This is crucial for ensuring the safety and efficiency of airport operations.

Air traffic control is responsible for coordinating the movement of aircraft and vehicles on the airside, and having clear communication with them is essential for preventing accidents and ensuring that all vehicles operate in compliance with the established airside regulations. This includes receiving instructions about what routes to take, when to stop or proceed, and any relevant safety information related to ongoing air traffic.

In contrast, solely communicating with other vehicles, while potentially useful in certain scenarios, does not fulfill the broader requirement of safety and coordination that ATC provides. Broadcasting traffic updates or enabling automated vehicle operations may also play a role in vehicle operation but do not replace the necessity of direct communication with air traffic control for compliance with safety protocols. Thus, the correct answer emphasizes the importance of adherence to air traffic control instructions, which is central to maintaining safety in the busy airport environment.
