FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

The correct answer is C, decreases. In very cold weather, metal contracts due to the decrease in temperature. This contraction would cause the cable to become shorter, which would result in a decrease in tension. However, the control system could still become variable if the contraction is not evenly distributed throughout the entire cable. Option A is incorrect because an increase in tension would only occur if the metal expanded in warmer temperatures. Option B is incorrect because the change in temperature would cause some form of contraction or expansion, leading to a change in tension. Option D is incorrect because there is a specific and predictable effect on the cable tension in this scenario.
