When an aircraft carrying distinguished visitors is at YYC, what are unauthorized personnel and vehicles required to do?

The correct action for unauthorized personnel and vehicles when an aircraft carrying distinguished visitors is present at YYC is to remain clear of the aircraft. This requirement is in place to ensure the safety and security of both the aircraft and its passengers.

Distinguished visitors often include high-profile dignitaries or officials, and specific protocols are established for their protection. Keeping unauthorized personnel and vehicles at a safe distance minimizes the risk of any security breaches and allows for a controlled environment where only authorized individuals can approach the aircraft. This helps to maintain the integrity of security measures and prevents any potential disruptions or threats.

Remaining clear of the aircraft also helps ensure that the designated personnel responsible for managing the aircraft's arrival and departure can perform their duties without interference, thus facilitating a smooth operation.
