What ceiling and visibility conditions permit facilities using safety logic systems to authorize landing options?

The correct answer indicates that a ceiling of 800 feet or more combined with visibility of 2 miles or more allows facilities using safety logic systems to authorize landing options. This specific threshold is significant because it balances both vertical and horizontal visibility requirements that ensure safe landing operations without compromising safety protocols.

Having a ceiling of 800 feet ensures that there is enough vertical space for various aircraft types to approach and land safely while still accounting for operational standards and potential weather variations. The visibility requirement of 2 miles is adequate for pilots to make visual references during approach and landing, which is crucial for safe flight operations in differing weather conditions. These parameters align with safety logic systems designed to optimize landing outcomes while adhering to safety regulations.

Other options might propose either overly restrictive or lenient conditions that do not align with the standards adopted by safety logic systems for landing authorizations, thus making them less suitable for ensuring operational safety in varied weather scenarios.
