What is defined as the art and science of managing resources available to a single pilot?

The correct answer is Single Pilot Resource Management. This concept revolves around the effective and efficient use of all resources available to a pilot when operating an aircraft alone. It encompasses the pilot's ability to manage everything from their own physical and cognitive skills to various external resources such as technology, tools, and available information.

Single Pilot Resource Management emphasizes decision-making, situational awareness, task management, and communication, particularly in situations where a pilot is operating without a co-pilot. It teaches pilots to recognize their limitations and utilize every asset at their disposal to enhance safety and flight performance. This holistic approach is critical for maintaining safety and efficiency, especially in single-pilot operations where the pilot must be adept in utilizing all available resources effectively.

Other choices might include elements related to resource management but do not accurately capture the specific focus that Single Pilot Resource Management encompasses for a pilot operating independently.
