Weather technicians will task-certify ATC personnel to evaluate prevailing visibility values from whom?

Weather technicians will task-certify ATC personnel to evaluate prevailing visibility values from whom?

• A. ATC supervisors
• B. METAR technicians
• C. Flight operations
• D. Control tower

Answer: (D)

Operational visibility data used by ATC come from the control tower’s weather observer, the person in the tower who collects and reports surface conditions that affect airfield operations. Weather technicians train ATC personnel to evaluate prevailing visibility values from this source because it provides the real-time, site-specific visibility information ATC relies on for decisions and clearances. METAR technicians produce standardized official observations that include visibility, but the immediate, day-to-day values ATC uses are those observed from the control tower.
