What does the term "hardwire" refer to in aircraft systems?

The term "hardwire" in aircraft systems refers to connecting systems directly, typically involving physical wiring rather than relying on any type of remote communication or control methods. This direct connection ensures reliability and stability in the operation of critical systems. By hardwiring, aircraft systems can achieve a more dependable performance, as it eliminates potential points of failure that could arise from wireless connections or other non-direct methods.

This direct connection can be crucial in certain applications where the integrity of information and control must be maintained, such as in avionics or critical flight management systems. Overall, hardwiring is utilized for its robustness and increased safety in aircraft operations.
