After having recently upgraded the Instrument Landing System (ILS) at the Chandigarh international airport to Category-II, the Airports Authority of India (AAI) has initiated the process to further enhance its capability to Category-III, which will permit aircraft operations in zero visibility.
The Category-II ILS at the airport, at present, permits operations in a visibility of 800 metres. The Category-III system will be able to guide an aircraft to within 50 metres of the touchdown point on the runway.
