CAT IIIb Landing
In the context of aerospace engineering, CAT IIIb Landing refers to a category of Instrument Landing System (ILS) that allows aircraft to land in extremely low visibility conditions, often in scenarios where the runway is not visible to the pilot. This system is a part of the broader aircraft landing system that uses radio signals to guide aircraft during landing. CAT IIIb Landing specifically allows for a decision height lower than 50 feet or no decision height and a runway visual range less than 200 feet but not less than 75 feet. This means that the aircraft can land almost entirely by relying on its onboard instruments and systems, with minimal visibility required. The implementation of CAT IIIb Landing requires advanced onboard equipment and ground infrastructure, including transmitters, receivers, and precision approach path indicators. It also necessitates rigorous pilot training to handle the complexities of such operations. The use of CAT IIIb Landing has significantly improved the safety and efficiency of aircraft operations in adverse weather conditions.
