Before an approach in a CAT D aircraft, what must the pilot be aware of?

Prior to executing an approach in a CAT D aircraft, the pilot must be particularly aware of the conditions of the runway. This is crucial because runway conditions directly impact the safety of the landing, especially for large and complex aircraft categorized as CAT D. These aircraft may require longer landing distances and specific handling characteristics that can be significantly affected by runway surface conditions such as wetness, snow, ice, or other obstructions. Understanding these conditions helps pilots to plan accordingly, taking into account factors such as required runway length, stopping distances, and overall landing performance.

While awareness of other factors such as aircraft capabilities and weather conditions is also important for safe operations, the immediate impact of runway conditions is vital at the time of approach since they can dictate whether it is safe to land and how the landing will be executed.
