In a move that would reduce the pressure on the Indira Gandhi International Airport (IGIA) here during winters, the AAI has upgraded Jaipur and Lucknow airports to CAT-IIIB level, which would allow them to operate flights in visibility up to 50 meters.
Till now IGIA was the only airport in the country equipped with ILS precision approach CAT-IIIB operations.
The task to upgrade Jaipur and Lucknow airport to ILS CAT-IIIB operations is accomplished by AAI on the assigned target date. With effect from December 8, 2016, Jaipur and Lucknow airports have become CAT-IIIB compliant airports.
Earlier Jaipur Airport was equipped with ILS, precision approach CAT-I and with this procedures aircraft were able to land when Runway Visual Range of 550m or more.
Similarly Lucknow airport was also equipped with ILS precision approach CAT-II and under this procedure aircraft were only able to land with Runway Visual Range is 300M or more.
Now Jaipur and Lucknow airports are 2nd and 3rd airports in India equipped with ILS precision approach CAT-IIIB operations.
At Jaipur and Lucknow airports aircraft will be able land with Runway Visual Range of 50M or more.
With the implementation of ILS CAT-IIIB operations from Jaipur and Lucknow airports, aircraft will face less delay or cancellation of flight during the winter fog season.
The problem faced by passengers during fog period would be reduced with the new upgraded CAT-IIIB system which fully supports continued flight operations and ground movement of aircraft during periods of low visibility (when RVR is as low as 50m).
Moreover, by upgrading the Jaipur and Lucknow airports to CAT-IIIB level, the traffic bound for IGI airport can now be diverted to Jaipur and Lucknow during the peak foggy season which, in turn, will lessen the burden at IGI airport as well.
