Which of the following is NOT a requirement for safe ground equipment operation?

Operating ground equipment during low visibility is not a requirement for safe ground equipment operation, and in fact, it poses a significant safety risk. In aviation operations, visibility plays a crucial role in ensuring that not only the equipment operators but also all personnel involved are able to see their surroundings clearly. Proper visibility allows for better judgement and reflexes, reducing the likelihood of accidents or collisions on the ramp.

The requirements for safe operations, such as turning the engine off before parking, conducting a 360-degree walk around before connecting ground support equipment, and chocking the aircraft, are implemented to enhance safety and mitigate hazards. These practices ensure that the equipment is safely secured and that operators are aware of their surroundings before engaging with aircraft or other ground operations. Low visibility conditions can impede this awareness and increase the risk of accidents, making it crucial to avoid operating equipment under such conditions unless absolutely necessary and with appropriate precautions in place.
