When must vehicle operators use VSRs (Vehicle Safety Radios)?

Vehicle Safety Radios (VSRs) are essential communication tools within an airport environment, particularly for enhancing safety and coordination among vehicle operators. The correct scenario for using VSRs is when moving between operational stands. This is crucial because operational stands are often located in active areas of the airport where communication is necessary to ensure the safety of personnel, aircraft, and ground operations.

When vehicle operators are moving between these stands, they may come into proximity with other vehicles and aircraft, increasing the risk of incidents. Using VSRs allows operators to receive real-time updates and communicate their movements, ensuring everyone is aware of potential hazards and can respond accordingly. This proactive approach is vital for maintaining safety protocols in busy and complex airport operations.

In contrast, using VSRs in any vehicle, only on busy runways, or during downtime does not reflect the specific operational protocols required for moving between operational stands, which is a critical phase for coordination and safety in an airport's airside operations.
