Chennai Flight Diversion After Diwali Smoke Cuts Visibility

A Chennai-bound IndiGo flight was diverted to Bengaluru due to Diwali-smoke-induced reduced runway visibility, with the diversion confirmed by multiple outlets noting that the flight could not land safely at Chennai’s Meenambakkam airport. Urbanacres.in reported that the IndiGo aircraft en route to Chennai diverted after the runway visibility fell below the airport’s landing limit, prompting the change in plan and making Bengaluru the alternate destination. No injuries or additional aircraft specifics were disclosed in that source.

DT Next expanded on the event by detailing the broader disruptions caused by the smoky conditions. They reported that 26 flights were affected at Chennai airport that night, with 11 arriving flights delayed and 15 departing flights delayed or late. ATC officials monitored runway visibility as a dense smoke blanket enveloped the runway area, and the Airports Authority of India prepared for possible visibility issues, allowing landings and takeoffs only when the runway was clearly visible. The IndiGo flight from Raipur, carrying 156 passengers, could not land in Chennai and subsequently diverted back to Bengaluru after hovering near the airport, adding to passenger disruption amid the smoky conditions.

The Times of India provided a more precise timeline and details about the specific IndiGo flight involved. They identified the aircraft as IndiGo 6E2002, operating the Raipur to Chennai routing with 78 passengers on board, and stated that the diversion occurred at about 11:15 pm after the pilot determined that the runway visibility did not meet the minimum requirement for a safe landing. Chennai airport officials indicated prevailing visibility around that time was approximately 900 metres, which was below the runway visual range threshold of 950 metres for landing on runway 07. The flight was originally scheduled to land around 10:45 pm before diverting to Bengaluru, and later returned to Chennai to land at 1:54 am, according to The Times of India.

Across the reporting, authorities framed the diversion as a precautionary measure prompted by degraded visibility caused by the Diwali-related smoke. The DT Next account reiterates that landings and takeoffs were only allowed when the runway was clearly visible, with ATC and airport operations closely managing movements under the smoky conditions. The Times of India note on the 1:54 am landing for the diverted aircraft aligns with the broader account of a nighttime disruption and the eventual resumption of operations after a precautionary diversion.

Residents around Meenambakkam airport were cited by DT Next as reporting continued cracker use beyond permitted times, contributing to deteriorating air quality and visibility despite some earlier rain. This detail helps explain the persistent smoky conditions that night, though it is not presented as a causal determination for the diversion itself. The material does not assign blame or specify any injuries or fatalities, and no additional operational details about the aircraft beyond the IndiGo 6E2002 designation in The Times of India reporting are provided.

Taken together, the reports confirm that a Chennai-to-Raipur flight operated by IndiGo was diverted due to smoke-induced reduced visibility, with Bengaluru serving as the diversion point before the aircraft eventually returned to Chennai on a subsequent flight. The affected operations encompassed both arriving and departing movements at Chennai airport, with 11 inbound flights delayed and 15 outbound flights delayed or late, and a broader disruption to 26 total flights at the airport that night, all ascribed to the smoky conditions surrounding Diwali celebrations, according to DT Next.

In summary, the incident involved an IndiGo Raipur→Chennai flight (6E2002) diverted to Bengaluru due to smoke-related visibility degradation from Diwali fireworks, with Chennai airport’s reported visibility around 900 metres versus a 950-metre minimum for landing on runway 07. The diversion occurred around 11:15 pm, the aircraft subsequently returned to Chennai and landed at 1:54 am, and no injuries or fatalities are reported in the supplied material. The event affected both inbound and outbound flights at Chennai, with ATC enforcing strict visibility-based landing and takeoff rules during the smoky conditions, and residents reporting ongoing cracker activity in the area that night.
