Which components must the crew check during the de-icing inspection?

During the de-icing inspection, it is crucial for the crew to thoroughly check all aircraft critical surfaces, engine inlets, and pitot/static ports. This is because ice accumulation on these surfaces can significantly affect the aircraft's performance and safety.

Critical surfaces encompass areas such as wings, tail, and control surfaces, which are essential for maintaining aerodynamic efficiency and control. Ice on these surfaces can lead to increased drag, reduced lift, and potential control issues. Engine inlets also need to be inspected as ice buildup can disrupt airflow, compromising engine performance. The pitot/static ports, which are integral for accurate airspeed and altitude readings, can become obstructed by ice, resulting in erroneous instrument readings.

In contrast, checking cabin luggage and fuel levels does not directly relate to the aircraft's performance during icing conditions. Likewise, while weather radar and communication systems are critical for overall flight operations, they are not part of the physical integrity checks performed during a de-icing inspection, which focuses specifically on surfaces that directly influence safety and performance in adverse weather.
