When dense fog descends at the Indira Gandhi International (IGI) Airport in Delhi this winter, expect better flight operations.
According to the civil aviation ministry, the total number of pilots with different airlines trained to use CAT II and CAT III Instrument Landing System (ILS) has gone up to 2,048 from around 1,500 last year.
The CAT III ILS guides pilots to land an aircraft in near zero visibility if they are trained to use the system and their aircraft are compliant.
At a meeting on fog management held on Wednesday under the chairmanship of secretary civil aviation, the fog preparedness of all agencies was assessed.
The Airports Authority of India (AAI), which handles air traffic at the Delhi airport, has been asked to prepare a priority setting procedure in departure of aircraft during fog and after improvement of visibility. AAI will also keep nearby airports ready to accept flights diverted from the Indira Gandhi International Airport.
The two main runways at the airport will be used in mixed mode operation for distributing traffic from fog as well as noise point of view.
The private airport operator, Delhi International Airport Ltd. (DIAL), has been advised by the ministry to explore possibility of making weather information/fog forecast available on Flight Information Display Systems within the passenger terminal and city side.
Websites of airlines and helplines will be monitored for timely dissemination of flight information to passenger during the fog period.
The directorate general of civil aviation has been asked to review the schedule of small aircraft that cannot operate in foggy conditions.
