What safety measure can be taken to avoid collisions on the ramp?

Using constant radio communication among ground staff is a vital safety measure to prevent collisions on the ramp. This constant line of communication allows team members to quickly share information about aircraft movements, machinery operation, and any potential hazards. When all personnel are connected through radio communication, they can call out their positions and intentions, providing situational awareness that is crucial in a busy ramp environment. This helps to coordinate activities more efficiently and reduces the likelihood of accidents by ensuring that everyone is informed and can react promptly to the evolving situation.

The other options may not directly address the unique challenges of ramp operations or could introduce further complications. For instance, increasing the number of tugs might lead to congestion rather than improving safety. Limiting operation hours could reduce efficiency and may not effectively mitigate collision risks during peak times. Maintaining a minimum distance between aircraft is a good practice but does not account for dynamic situations that require real-time communication to avoid risks effectively.
