Before approaching an aircraft, what critical step must all vehicle operators perform?

Check the weather conditions.
Test their brakes.
Notify the control tower.
Calculate the aircraft's weight.

The correct answer is: Test their brakes.

Before approaching an aircraft, it is crucial for vehicle operators to test their brakes to ensure they can stop safely and effectively. The airport environment can be busy with various aircraft and personnel, making it essential that any vehicle operates in a controlled manner. Testing brakes not only ensures the safety of the vehicle operator but also protects the aircraft, as there may be limited space to maneuver. Proper brake function is vital to avoid accidents that could lead to serious damage or injury. While checking the weather conditions, notifying the control tower, and calculating the aircraft's weight are important considerations in their respective contexts, they do not directly relate to the immediate safety practices for vehicle operators approaching an aircraft. Therefore, testing brakes stands out as the critical step to ensure a safe approach.
