Which of the following is considered a safety protocol when parking near an aircraft?

Ensuring the vehicle is visible to cockpit personnel is a vital safety protocol when parking near an aircraft because it enhances situational awareness both for the vehicle operator and the flight crew. When cockpit personnel can see vehicles parked nearby, they have a clearer understanding of their environment, reducing the risk of accidents during critical moments such as taxiing or takeoff. This visibility helps prevent the vehicle from becoming an unexpected hazard, which is particularly important in the high-stakes atmosphere of an airfield.

Maintaining visibility contributes to a safer overall operation, as it allows both pilots and vehicle operators to act accordingly based on their observations, helping to avoid misunderstandings and potential collisions. Therefore, prioritizing visibility is essential for effective communication and safety on the airfield.
