Chennai Airport Cancels Flights Due To Low Visiblity 'Dense Fog'

Severe fog and poor visibility affected operations at Chennai International Airport early Wednesday, leading to the implementation of Low Visibility Procedures (LVP) and the cancellation of several flights. 

According to airport weather data, visibility remained stable at around 4,000 metres from midnight until 1:00 am, before gradually deteriorating. By 4:00 am, visibility had dropped to 2,000 metres, prompting airport authorities to declare a visibility standby.

Safeguarding procedures were initiated shortly afterwards at 4:45 am as conditions continued to worsen. By 5:30 am, visibility had reduced to 1,000 metres, and Runway Visual



Range (RVR) for Runway 07 fell to 1,200 metres. 

Conditions deteriorated further by 6:00 am, when visibility dropped to 800 metres and RVR to 900 metres. As a result, Low Visibility Procedures were officially implemented at 6:00 am.

The situation became most severe between 7:00 am and 8:00 am, when visibility plunged to just 300 metres, with RVR at 400 metres. 

Despite these challenging conditions, airport authorities stated that flight operations continued under LVP and were reported as being under control. However, the bad weather forced the cancellation of several flights scheduled for later in the day.
