During low visibility operations, what happens to ILS Hold Short rules?

During low visibility operations, the Instrument Landing System (ILS) Hold Short rules are enforced to ensure safety and maintain proper separation between aircraft and runways. Low visibility conditions can significantly affect pilots' ability to see and assess their surroundings, making strict adherence to hold short rules essential to prevent runway incursions and collisions.

Enforcing these rules means that pilots are required to follow prescribed protocols for taxiing, holding short of active runways, and ensuring they have clearances from air traffic control before proceeding. This level of enforcement helps prevent accidents and ensures that operations can continue smoothly, even when visibility is compromised.

In contrast, simply relaxing the rules or treating them as only advisory would increase the risk of hazardous situations, which is not acceptable in aviation practice. Therefore, adherence to enforced holding short rules during low visibility conditions reflects a proactive approach to safety.
