If you are planning to catch a flight on a Friday Afternoon across the country, expect a delay in most flights. You can blame it all on the Mumbai Runway closure.When the country’s busiest airport has a pair of cross-runways, the mandatory closure for weekly repairs affects airline schedules across the country. “As per the International Civil Aviation Organisation (ICAO) norms, operational runways have to be periodically maintained. Accordingly, in Mumbai the main runway stays closed from 11.30am to 1.45pm and the secondary runway remains closed for 30 minutes from 1.15pm.
This is what happens every Friday afternoon. At 11.30am, the main runway in Mumbai is closed and maintenance work begins. It includes removing burnt rubber to correct the runway co-efficient of friction, checking runway lights, painting marked surfaces like the runway central line and so on. At 1.15pm, similar work on runway intersection begins and both runways are closed.
By 1.20pm flights start hovering overhead to land. This despite the airline knowing that the runway will be closed. By 1.45pm, when it is time to reopen, there are six to seven flights in the landing sequence. From there on, the cascading delays begin, Delay announcements get going by early Friday afternoon in airports across the country. About 90% of all aircraft that operate domestic flights land in Mumbai at least once in their day’s schedule. So a delay in Mumbai means a delay in every airport of the country. Thousands of passengers are affected by this.
The most important question in here is why dont the airlines and airports work out chaging schedules on Fridays to circumvent this issue.
