What are the two classifications of AVOP at YVR?

The classification of AVOP at YVR into Drivers/Operators (D/A) and Drivers (D) is correct because it clearly differentiates between the various responsibilities and access levels for vehicles operating in the airside area.

Drivers/Operators (D/A) are trained to access and operate vehicles in areas where aircraft are present, requiring a higher level of training due to the complexities and safety protocols involved in those zones. This includes understanding air traffic control procedures, aircraft movements, and potential hazards present on the airside. On the other hand, Drivers (D) are typically limited to non-operational areas or landside operations, which do not require the same depth of understanding of aviation regulations and safety measures.

This classification is essential for ensuring that all vehicle operators on the airside are properly trained and familiar with the specific rules and responsibilities that govern their activities, thereby enhancing safety and operational efficiency at the airport.
