What is the first fundamental skill in attitude instrument flying?

The first fundamental skill in attitude instrument flying is instrument cross-check. This skill involves continuously monitoring and interpreting multiple instruments to maintain control of the aircraft's attitude. Instrument cross-check is crucial because it allows a pilot to gather data from various sources and make informed decisions about the aircraft's performance and position in the flight environment. By effectively cross-referencing readings from different instruments, a pilot can ensure that they are achieving and maintaining the desired altitude, course, and speed, ultimately leading to safer and more precise flying.

While other skills such as altitude adjustments, aircraft control, and instrument interpretation are also vital in instrument flying, they are secondary to the ability to cross-check instruments efficiently. Mastery of instrument cross-check serves as the foundation for effective instrument navigation and increases a pilot's situational awareness, making it the first fundamental skill in this discipline.
