What effect will exceptionally tight control cables have on an airplane's flying characteristics?

When control cables are exceptionally tight, it increases the tension in the system, which can lead to a heavier feel on the flight controls. This is because the pilot must exert more force to move the control surfaces, resulting in a greater resistance when attempting to maneuver the aircraft. Such tightness can reduce the sensitivity and responsiveness of the controls, as the need for forceful inputs can inhibit quick or subtle adjustments in response to changing flight conditions.

In general, a properly adjusted control system should provide a balance that allows the pilot to feel connected to the aircraft without overly straining to move the controls. Excessive tension introduces a level of difficulty that can hinder pilot performance and overall aircraft handling.
