CAT-3B system improves Bengaluru airport runway visibility

Bengaluru, Dec 31 : The Bengaluru International Airport installed the category-3B (CAT-3B) instrument landing system (ILS) on its new runway to improve visibility for aircraft landing and take-off in inclement weather and foggy conditions, said its operator on Thursday, “The new runway has been upgraded with CAT-3B ILS to enable any aircraft landing at 50-metre visual range and take-off at 125-metre visibility,” said the operator (Bangalore International Airport Ltd) in a statement here.
A CAT-3B helps pilots with a precision approach and landing when the runway visibility is at a distance less than 50 feet (15 metre) and take-off at a visual range less than 200 metres.
The city airport becomes sixth in the country to have a CAT-3B runway for better visibility in the night and early hours of the day.
The CAT-3B is aided by airfield ground lights, transmission metre, automatic weather observatory station, surface movement radar and navigational aids.
The directorate general of civil aviation (DGCA) inspected the CAT-3B complaint runway after the airport secured regulatory approvals to operate the runway on completion of trial and calibration flights.
