Possibility of tailwind, reasons for runway change and safety parameters of runway under probe in Kozhikode flight mishap

A day after the Air India Express flight mishap at Kozhikode international airport in Kerala, the questions doing the rounds are what made the pilot opt runway-10 though runway-28 was initially considered and whether the tabletop runway lacked adequate safety parameters.

Aviation experts suggested that the prima facie reason for the aircraft overshooting the runway could be tailwind or crosswind.

Team of DGCA and AIE already reached the spot. With the death of the captain and co-pilot in the mishap, the investigation would be focusing mainly on the voice recorders and other technical aspects.

It is learnt that the ill-fated aircraft, IX 1344 with 190 onboard including crew, was initially planning to land on runway-28 of the airport. But later the pilot opted runway-10 which is toward the other direction. Pilots would be taking the decisions on the basis of inputs from ATC.

Though the Karipur airport has an Instrument Landing System, it was of category-I for which pilot's visibility is very crucial toward a touchdown. Since it is a tabletop airport and rough weather prevailing in the region, the chances of tailwind was also high, said sources.

There had been safety concerns about the Karipur airport over quite some time. In 2011 aviation safety consultant captain Mohan Ranganathan reportedly gave a report citing the safety issues, especially the buffer zones at the end of the runway.

However, an AAI officer said that rectification steps were already done by last year by widening the Runway End Safety Area (RESA) from 90 metre to 240 metre. However, the length of the runway had to be reduced to 2,700 metre from 2,850. The AAI was also constantly pressing for increasing the runway length to 3,150 metres. But that was getting delayed due to land acquisition issues pending with the state government.

An aviation expert, who didn't want to be quoted, said that Capt Deepak Sathe, who was commandeering the aircraft, was a well-experienced pilot and was also familiar with the terrains. Hence the chances of any error from his part was very unlikely. Hence a fair in-depth probe was required to find the exact cause.
