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 a significant drop in demand attributed to the widespread use of real-time cockpit weather services like ADS-B In.
- Introduced in the 1980s, HIWAS provided continuous hazardous weather information via VOR frequencies as an alternative to pilots contacting Flight Service Stations for updates.
- While initial safety concerns were raised by groups such as AOPA, a Safety Risk Management Panel, including AOPA, unanimously supported the discontinuation, concluding it would not add risk to the National Airspace System, with FIS-B and FSS cited as sufficient alternatives.
