At all EUs, the local ceiling, prevailing visibility, and runway visual range minima for landing and circling minima will be SPECI observations generated by which systems?

• A. The Weather Technician
• B. Automated Meteorological Observing Systems (AMOS) or the Weather Technician
• C. Automated Weather Observing System
• D. Meteorological Observation Network

Answer: (B)

Special weather observations (SPECI) are issued whenever a significant change in weather could affect flight operations, and in the Air Force context the sources for generating those SPECI reports are the Automated Meteorological Observing System (AMOS) or the Weather Technician. AMOS continuously measures ceiling, prevailing visibility, and runway visual range (RVR) and can automatically produce METAR/SPECI reports reflecting the current minima used for landing and circling. If AMOS is unavailable or a manual observation is required, a Weather Technician will generate the SPECI to ensure timely, accurate reporting of those same minima for aircrew planning and operations. Other systems like AWOS or a general Meteorological Observation Network aren’t the designated sources specifically referenced for SPECI generation in this scenario.
