How can a pilot detect ice on the wing?

• A. By a vibration in the control yoke
• B. By a loss in airspeed
• C. By a rise in engine temperature
• D. By an increase in fuel consumption

Answer: (B)

Detecting ice on the wings is critical for pilot safety, as ice accumulation can significantly affect aircraft performance. The correct answer regarding how a pilot can detect ice on the wing is related to the loss in airspeed. When ice forms on the wings, it disrupts the smooth airflow over the surface, which can lead to a change in the aerodynamic characteristics of the aircraft. This disruption typically results in a stall speed increase, leading to a loss in airspeed. The pilot may notice that the indicated airspeed is lower than expected for a given power setting and altitude, signaling potential ice presence. It's important to note that while vibrations in the control yoke can sometimes indicate issues with the aircraft, they are not a direct or reliable indication of ice accumulation. Similarly, a rise in engine temperature could be influenced by various factors unrelated to wing ice, and an increase in fuel consumption may arise from changes in engine performance, which could also occur for numerous reasons that do not specifically point to ice on the wings.
