What is a recorded hazardous in-flight weather forecast continuously broadcasted to airborne pilots over selected VOR outlets?

• A. HIWAS
• B. MIS
• C. CWA
• D. TAF

Answer: (A)

This item focuses on how pilots receive hazard warnings while en route. The best answer is Hazardous In-Flight Weather Advisory Service, the recorded hazardous weather forecast that is continuously broadcast to airborne pilots over selected VOR outlets. HIWAS provides warnings like SIGMETs, AIRMETs, Convective SIGMETs, and urgent weather messages, updating as new information becomes available, so pilots can plan around dangerous weather without relying on real-time briefing from ground stations. It’s specifically designed for en-route awareness via VOR broadcasts rather than airport-specific forecasts. The other options aren’t continuous VOR broadcasts of en-route hazards: MIS isn’t that service, a Center Weather Advisory is distributed to ATC and pilots but not a continuous VOR broadcast, and a TAF is a forecast for a particular airport, not a en-route hazard broadcast.
