Do manual control systems require a pilot device to function?

In manual control systems, the operation does not inherently require a pilot device to function. Manual control focuses on using human input directly to control a system without intermediary devices that automate the process. This means that in a purely manual setup, the operator can directly manipulate controls such as switches, levers, or dials to influence system behavior without relying on a pilot device like sensors or automated controls.

Pilot devices are often used to enhance the control process or add functionality, but they are not a fundamental requirement for the operation of a manual control system. Consequently, it is entirely possible for these systems to function effectively without pilot devices, depending on the specific design and application of the control system.
