If flying into MSP and all nearby airports have 0/0 weather, what should you do?

The most appropriate action when approaching an airport, such as MSP, with surrounding airports reporting 0/0 weather (zero visibility and zero ceiling) is to perform an ILS Category III (Cat III) approach, provided that the aircraft is equipped for such an operation and the crew is trained and certified to conduct it.

ILS Cat III approaches allow pilots to land with very low visibility conditions, as they utilize advanced systems that can provide precise lateral and vertical guidance. This means that if the aircraft is equipped with autoland capabilities and the pilots are qualified, it can successfully land without relying on visual references. Hence, if the weather at MSP permits a Cat III approach, it is a prudent course of action to safely land the aircraft.

In contrast, diverting to an alternate airport may not be necessary if landing is possible at MSP under the Cat III criteria. Attempting a visual landing is ill-advised when reporting zero visibility, as it depends on visual cues that simply aren't available in such conditions. Hanging in a circular pattern until conditions improve could lead to unnecessary fuel burn and increased risk, particularly since other surrounding airports are also reporting zero visibility. Thus, executing a Cat III ILS approach offers the most effective and safe solution for landing under those adverse
