What single reference contains information regarding a volcanic eruption?

In-Flight Weather Advisories are specifically designed to provide pilots with real-time information that could impact their flight operations, including safety hazards such as volcanic eruptions. These advisories include critical updates about weather phenomena, including ash clouds or eruptions that may affect airspace and flight paths. Such information is essential for pilots to make informed decisions during flight.

The other options don’t primarily focus on volcanic eruptions. Current Aviation Weather Reports are more general weather updates that may not specifically highlight volcanic activity. Flight Service Stations provide a range of flight assistance services, but they are not the singular source for eruption information. Pilot Logbooks record flight details and experiences but do not provide information about current erupative events. Thus, In-Flight Weather Advisories stand out as the most relevant choice for information on volcanic eruptions.
