On What Frequency Can A Pilot Receive Hazardous Inflight Weather Advisory Service (Hiwas)
Dec. 19, 2019
The FAA volition discontinue the Hazardous Inflight Weather Advisory Service (HIWAS) in the contiguous United States, effective January. 8, 2020. HIWAS is a continuous circulate of weather advisories over a limited nationwide network of VORs, providing pilots with information related to chancy weather.
The agency'southward decision comes in the wake of decreased demand for inflight services from flight service specialists in general, dropping from an average of more than x,000 radio contacts per 24-hour interval to less than 900 per twenty-four hour period, which the FAA said is an indication pilots are using other means to obtain atmospheric condition data.
NBAA participated in an FAA/manufacture Safety Risk Management (SRM) Panel that analyzed the risks associated with discontinuing this service and addressed stakeholder concerns.
"NBAA was a part of the SRM procedure, and is comfy with the decommissioning of this service in the lower 48 states, as there are numerous other products that provide pilots with the needed conditions information," said Heidi Williams, NBAA's director of air traffic services and infrastructure.
"We no longer rely solely on the aircraft radio for access to weather data in the cockpit. Instead, we have access to a number of resources that we didn't when HIWAS was created," she added. "This greatly mitigates any touch on of decommissioning what we found in the class of our review to exist a little used production."
Further, newer sources for inflight weather information typically nowadays cloth in a graphical format, which is often easier to use while flight.
Air traffic controllers will continue to advise pilots of chancy weather that may affect operations within 150 miles of their sector or area of jurisdiction. This includes details found in Airmen's Meteorological Data, Meaning Meteorological Data, Convective SIGMENT, Urgent Pilot Reports and Center Weather Advisories. Pilots will exist instructed to contact a flying service specialist through air-to-ground radio frequency if they demand boosted information.
