What does PCL stand for in aircraft controls?

PCL stands for Pilot Control Level, which refers to the input devices used by a pilot to control the aircraft's systems and performance. In the context of flight controls, the Pilot Control Level encompasses the interfaces like the control yoke or stick, throttle, and other essential controls that a pilot manipulates to command the airplane's flight path, speed, and rate of climb or descent.

In an aircraft, these controls are critical for ensuring precise handling and maneuvering, reflecting a pilot's intent to navigate safely and efficiently. The term specifically highlights the pilot's role in manipulating these controls as opposed to automated systems or other forms of control. Understanding the PCL is fundamental for pilots as it forms the basis of their interaction with the aircraft's systems.
