ILS Category IIIC: Provides for approach without a decision height minimum and without runway visual range minimum.

ILS Category IIIC Definition

ILS Category IIIC refers to a specific category of Instrument Landing System (ILS) that provides a highly automated and precise approach to the runway for pilots. This category of ILS allows for an approach without a decision height minimum or runway visual range minimum, which means pilots can rely solely on the aircraft’s instruments to land the plane safely in very low visibility conditions.

To meet the requirements of ILS Category IIIC, an airport must have advanced equipment and systems in place, such as multiple ground-based transmitters and precision approach path indicators. Additionally, the aircraft used for this type of approach must also be equipped with the necessary technology, including autoland systems that can land the aircraft without pilot input.

Overall, ILS Category IIIC provides a critical capability for airports and airlines to maintain operations during adverse weather conditions, reducing the need for diversions or cancellations. It represents a significant advancement in aviation technology and safety, allowing pilots to perform challenging approaches with confidence and precision.
