NTSB Issues Safety Recommendation A-14-002 to FAA Regarding Automated Weather Observing Systems

The National Transportation Safety Board (NTSB) has issued safety recommendation A-14-002, designated under reference number CEN13FA096, addressed directly to the Federal Aviation Administration. This directive concerns the operational parameters of automated weather observing system installations currently certified and deployed within the National Airspace System. Specifically, the NTSB is urging the FAA to implement modifications for those installations equipped with present-weather sensors. The core requirement of this recommendation mandates that these systems must report only snow or indicate unknown precipitation when two specific conditions are met simultaneously: precipitation is detected by the sensor, and the reported air temperature is 32 degrees Fahrenheit or less. This measure aims to ensure greater precision in weather data transmission during freezing conditions, thereby supporting safer aviation operations without introducing unverified speculative elements into the current reporting framework.
