Knowing current weather conditions and how they are expected to change is important information for pilots. Today, the primary source of information on current weather conditions is the network of automated surface weather observations. Those operated by the FAA are commonly called Automated Weather Observing Systems (AWOS). Pilots rely on the data from these stations to make operational decisions on whether to fly or not, augmented by the FAA Alaska Weather Camera Program, which during daylight hours provides a visual look at the weather.
The FAA Surveillance and Broadcast Services Program is primarily tasked to implement ADS-B and other technologies, in support of NextGen. As follow-on to the FAA Capstone Program, however, they undertook the challenge of adding additional AWOS stations, as well as a couple Remote Communication Outlets in some parts of Alaska. Working with FAA, Alaskan user groups argued that ADS-B alone wouldn’t improve safety and access—we needed a system solution that also included instrument approaches, weather and communications. Over the past few years, the SBS Program has installed twenty additional AWOS stations in Alaska. Improved IFR access is certainly a result at airports that have WAAS GPS approaches, which most have. In some cases, nearby airports with existing approaches were able to obtain lower minimums, based on these stations. In all cases, pilots have better weather information about these airports to aid their decision making, whether flying under VFR or IFR rules.
Currently the FAA is looking for feedback from users who fly in these areas, and would like to hear from individual pilots, air taxi operators, private business users, communities, or anyone else that has seen a change based on any of these twenty stations.
SBS Funded AWOS Stations
While these twenty stations are an improvement, Alaska is still very sparsely covered with aviation weather stations in comparison to the rest of the country. Additional weather stations are needed to improve aviation safety and access. Letting FAA know the benefits from these stations is a step in the right direction.
