Under low-visibility conditions, which actions support preventing runway incursions?

• A. Maintaining surveillance, issuing precise taxi routes, and coordinating with the tower
• B. Asking pilots to rely on onboard instruments without commands
• C. Allowing pilots to self-navigate without ATC guidance
• D. Reducing communication to minimize workload

Answer: (C)

Under low-visibility conditions, preventing runway incursions relies on active ATC control of ground movements through clear guidance and continuous surface surveillance. Maintaining surveillance lets controllers see where all aircraft and vehicles are on the movement area and detect potential conflicts before they become incursions. Issuing precise taxi routes removes ambiguity, giving pilots a specific path to follow and reducing the chance of straying onto a runway or between critical taxiways. Coordinating with the tower ensures that runway crossings and sequencing of movements are managed safely, with clear clearance and timely approvals when crossing runways. Relying on onboard instruments without external commands, or having pilots self-navigate without ATC guidance, eliminates the external check that prevents conflicts in the complex, dynamic surface environment. Reducing communication increases the risk of miscommunication and missed instructions, which is especially dangerous when visibility is poor. Together, precise directions, continuous monitoring, and coordinated tower actions create the safeguards needed to keep runways clear in reduced visibility.
