What additional details are included in a PIREP when icing is present?

When icing is present, a Pilot Report (PIREP) includes crucial information such as the type of icing encountered, its intensity, and the air temperature at the altitude where the icing is experienced. This information is vital for air traffic controllers and other pilots, as it helps assess the severity and potential impact of icing on flight safety.

Specifically, the type of icing (for instance, whether it is clear, rime, or mixed) provides insight into the conditions encountered by the aircraft. The intensity reflects how severe the icing is—ranging from trace to severe—which aids in determining how to manage and respond to icing conditions. The air temperature is particularly important as it can influence the likelihood of icing and the type experienced.

While other options may include relevant factors, they do not encapsulate the essential details specifically related to icing that are fundamental in PIREPs. For example, information about turbulence is related but does not pertain directly to icing, and details about humidity or wind speed, while helpful in some contexts, do not provide the critical data necessary for assessing icing conditions in flight. This makes the inclusion of type, intensity, and temperature in PIREPs particularly significant.
