What should drivers do when approaching an aircraft on the ground?

Maintaining a safe distance and following crew instructions is crucial when approaching an aircraft on the ground for several reasons. Aircraft, whether stationary or taxiing, require a controlled environment for safety. By keeping a safe distance, drivers can avoid the risk of accidents and ensure that both personnel and equipment are not endangered by the operation of the aircraft.

Following crew instructions is also vital. Aircraft crews have a comprehensive understanding of the aircraft's operational procedures and the surrounding environment. They can provide guidance based on the specific situation, including traffic patterns, potential hazards, or emergency protocols. This approach fosters effective communication and enhances safety on the airfield.

The other options may not prioritize safety or proper protocol. Accelerating to pass quickly could lead to accidents or miscommunication with crew members. Honking to get the crew's attention may startle personnel or distract them from their duties. Stopping and parking next to the aircraft can obstruct operations and violate safety regulations, potentially causing issues within the airfield environment. Thus, the best practice is to maintain a safe distance and adhere to crew instructions.
