What types of information does HIWAS contain?

HIWAS, or Hazardous In-flight Weather Advisory Service, is designed to provide critical information about weather conditions that might affect aviation. It broadcasts important updates on weather phenomena that could pose risks to flight safety, such as thunderstorms, severe turbulence, and other hazardous weather conditions in the vicinity of an airport or flight route.

This service includes significant weather advisories, pilot reports (PIREPs) regarding actual in-flight conditions, and relevant updates on various weather hazards. In this way, pilots can make informed decisions regarding their flight paths based on the latest and most relevant weather information.

The other options mentioned do not align with the primary function of HIWAS. While air traffic control updates pertain to current air traffic and flight operations, they do not encompass the specific weather information that HIWAS provides. Current flight paths would relate to airspace and traffic management, which is also outside the focus of HIWAS. Fuel prices are unrelated to flight safety and weather advisories, thus not part of this service's scope.
