With the growing use of real-time weather by pilots who have access to ADS-B In or other weather services in the cockpit, the FAA is making changes to its weather-related services. In a notice to the Federal Register issued on December 9, the FAA announced its intent to discontinue the Hazardous Inflight Weather Advisory Service (HIWAS).
FAA to Discontinue HIWAS
Key Takeaways:
- The FAA is discontinuing the Hazardous Inflight Weather Advisory Service (HIWAS) on January 8, 2020, due to significantly reduced demand attributed to the widespread availability of real-time in-cockpit weather services like ADS-B In.
- HIWAS, which broadcast continuous hazardous weather information via VOR frequencies since the 1980s, will be replaced by modern alternatives such as Flight Information Service-Broadcast (FIS-B) and continued access to Flight Service Stations (FSS).
- Despite initial safety concerns raised by groups like AOPA, a Safety Risk Management Panel, including stakeholders, unanimously supported the removal, concluding it would not increase risk to the National Airspace System.
