New Delhi: With foggy conditions approaching in north India, a system which aids landing and take-off of airplanes was today installed at the airport in Agra, which is a major tourist destination.
The Instrument Landing System (ILS), which facilitates low visibility aircraft operations, was made operational at Agra. It would make landing and take-off possible even when the visibility is as low as 800 metres.
The system is already in place at several airports across North India, including Delhi. It guides the airplanes for landing and take-offs in low-visibility conditions when Category-III ILS is in place.
Agra Airport, an Air Force airport with a civilian enclave maintained by the Airports Authority of India (AAI), so far had VHF omni-directional radio range (VOR) facility at the Airport for homing and landing of aircraft in visibility up to 2400 metres.
While VOR is a short-range radio navigation system that enables planes to determine their position and stay on course, ILS is a ground-based instrument approach system that provides precision guidance to an aircraft approaching and landing on a runway during reduced visibility, using a combination of radio signals and high-intensity lighting arrays.
The pilots also need to be trained to operate the ILS matching equipment on board an aircraft for flight operations in low visibility due to fog, rains or snowfall.
