Which of the following is NOT one of the six concepts that make up single-pilot resource management?

Time management is indeed an essential skill for pilots, but it is not specifically classified as one of the six concepts of single-pilot resource management (SRM). The six concepts of SRM focus on areas that directly relate to safe and effective decision-making and operational safety in flight. These concepts typically include aeronautical decision making, which involves evaluating situations and making choices; risk management, which focuses on identifying and mitigating risks; situational awareness, which is the understanding of current conditions and how they impact the flight; and others that together help a single pilot operate effectively under various conditions.

By recognizing that time management, while important, doesn't fit within the core framework of SRM concepts, it shows the distinction between vital skills for effective operation and the specific concepts that guide single-pilot operations. The other concepts are inherently linked to the challenges and decision-making processes that a single pilot faces, making them foundational to SRM training.
