Delhi airport to use next-gen AI and enhanced runways to tackle winter chaos

Indira Gandhi International Airport (IGIA) in Delhi, recognized as India's busiest aviation hub, is taking significant strides to enhance its operations amid the annual disruptions caused by thick winter fog. The airport operator, Delhi International Airport Limited (DIAL), has adopted next-generation Artificial Intelligence (AI) and advanced predictive analytics, coupled with substantial infrastructure improvements, to ensure safer and more efficient flight operations. A pivotal component of this initiative is the establishment of the Airport Predictive Operations Centre (APOC). This innovative center amalgamates real-time data, predictive weather models, and airside information into a single command system. Such integration empowers airport management to make prompt decisions, optimizing runway utilization, improving aircraft sequencing, and streamlining resource allocation during conditions of low visibility. One of the crucial technological advancements comes from utilizing data from the Winter Fog Experiment (WiFEX), a long-term research initiative. DIAL is leveraging this forecasting model, which boasts an impressive 85% prediction accuracy, to foresee dense fog conditions up to 36 hours in advance. This proactive early warning system enables airlines, Air Traffic Control (ATC), and ground teams to prepare accordingly, aiming to minimize delays and enhance reliability for travelers. In addition to technological upgrades, the airport has also completed a significant overhaul of its physical infrastructure. All three primary runways (1L/29R, 11R/29L, and 10/28) are now outfitted with CAT-III Instrument Landing Systems (ILS) at both ends. Notably, the recent enhancement at the Dwarka end of Runway 10/28 allows the airport to conduct landings safely, even in conditions of near-zero visibility. This improvement is critical, permitting the airport to accommodate approximately 30 landings per hour during heavy fog, thereby preserving schedules. DIAL projects that these comprehensive upgrades will substantially reduce the recovery time from fog-related disruptions from around six hours to just two hours, significantly minimizing inconvenience and safeguarding flight schedules throughout the challenging winter months.
