Which of the following describes a potential disadvantage of automated flight systems?

Automated flight systems, while offering significant advantages, including enhanced efficiency and consistency in operations, do come with the potential disadvantage of malfunctions. These systems rely on complex software and hardware, which can be susceptible to bugs, failures, or external interferences that could lead to unexpected behavior. When an automated flight system malfunctions, it may not respond as expected, potentially posing risks during critical phases of flight. Understanding this potential for malfunction is essential for remote pilots, as it emphasizes the need for thorough training and readiness to take manual control if necessary to ensure safety.

The other options present assertions that do not accurately capture the complexities of automated systems. While automation can improve efficiency and reduce the workload, it does not guarantee faster flight times or that it requires less pre-flight planning. Additionally, stating that automated systems are less reliable than manual control overlooks the fact that many automated systems are designed to enhance reliability and safety, although they can still present challenges.
