If weather worsens and visibility decreases, what is the recommended action?

• A. Stop and seek shelter or wait for clearance to resume.
• B. Call for assistance from a supervisor.
• C. Wait for ATC instructions or shelter.
• D. Ignore and proceed.

Answer: (C)

When visibility on the airfield drops, the priority is to stop and wait for proper guidance rather than continuing to move. The safe course is to hold your position and await ATC instructions, or move to shelter if conditions are unsafe for driving. ATC controls ground movements and has the latest weather and traffic information, so they determine when it’s safe to proceed or to clear you to resume. Proceeding without clearance can put you at risk of entering active taxiways or runways with poor visibility. Calling a supervisor isn’t the appropriate channel for real-time ground guidance, and ignoring the conditions to keep moving is unsafe.
