The Chhatrapati Shivaji Maharaj International Airport (CSMIA), one of the busiest airports, has been experiencing frequent congestion for the past few months leading to aircraft hovering overhead for a significant duration causing inconvenience due to passenger delay, wastage of fuel and environmental pollution, the press note said.

After many complaints the civil aviation ministry directed the Airport operator; Mumbai International Airport Limited (MIAL) and the Airport Authority of India (AAI) on January 2 to mitigate congestion by restricting the movements of non-scheduled flights (General Aviation) during peak hours (8-11 am, 5 pm and 8 pm and 9.15 pm and 11.15 pm)

Just 4% of arrivals were delayed over 30 minutes in the 16-24 February period compared to more than 26% during 11 November-10 December, the aviation ministry said. Similarly, 57% of flights arrived with a delay of 0-15 minutes and 26% with a delay of 15-30 minutes in the February stretch, against 25% and 14% in November-December.

CSMIA has two intersecting runways which cannot be operated simultaneously resulting in single runway operations with a peak hour declared capacity of 46 aircraft movement (arrival or departure) in an hour, during High-Intensity Runway Operations (HIRO) and 44 aircraft movement per hour (during NON-HIRO) period.

All the Domestic airline operators were also advised to strictly adhere to the slots allocated by MIAL to avoid air congestion and most of them have reduced flights.

The Air traffic situation at Mumbai post above initiatives is being monitored and has shown improvement from February 19 onwards.

The press note said that aircraft operating earlier than the approved slot (marked as before schedule in the data) lead to congestion and delay for other aircraft adhering to the schedule, which in turn, will have a cascading effect on the other schedule movements. The note said these movements were also targeted for improvements and airlines asked to adhere to the allotted slots.
