Why is it crucial for drivers to test their vehicle brakes when approaching an aircraft?

Testing vehicle brakes when approaching an aircraft is essential primarily to prevent brake failure or a collision. This action ensures that the driver has full control of the vehicle, allowing for safe maneuvers around the aircraft. Given the critical nature of operations at an airport, where large and stationary aircraft can be present, ensuring that brakes are fully operational minimizes the risk of accidents, which could lead to serious consequences for both people and property.

Maintaining control of the vehicle is vital, especially in a busy environment like an airport, where sudden stops may be necessary. Proper brake function enhances the driver’s responsiveness to any unexpected situations that might arise, such as an aircraft moving or unexpected obstacles on the ground. This proactive approach to vehicle safety is fundamental in aviation operations to uphold safety and security standards.
