Experts Cite Pilots’ Wrong Decision As Major Reason For Kozhikode Crash

New Delhi:

A gust of wind, fallacious resolution by means of the pilots, the situation of the air strip or even misguided indication by means of the tool touchdown gadget may well be conceivable causes for the crash of the Air India Specific on Friday in Kerala’s Kozhikode, in line with aviation mavens.

The dominant explanation why cited by means of the mavens used to be the verdict by means of the pilots not to divert the airplane to every other airport after the primary try to land on the designated strip failed amid rain.

The Boeing 737, bringing again 190 stranded Indians from Dubai, broke into items after it overshot the table-top runway 10 and fell right into a valley 35 ft beneath, leaving 18 other folks together with each the pilots useless.

“It’s silly to land with a tailwind on a rainy runway…That is what I’ve been declaring for years. I mentioned in 2011 that touchdown with a tailwind in rain on runway 10 will lead to an twist of fate in the future,” main professional Captain Mohan Ranganathan informed PTI.

Mr Ranganathan used to be a member of the operations workforce of the Civil Aviation Protection Advisory Committee (CASAC) in 2011. He has been part of more than a few different protection committees of aviation regulator DGCA.

Because the investigators start probe into the twist of fate, every other aviation professional referred to the “broadly recognised Swiss Cheese” style whilst speaking about conceivable causes for the crash that integrated breaking aside of the airplane’s fuselage.

“Any aeroplane twist of fate that occurs is rarely depending on a unmarried issue. Best air twist of fate investigation groups internationally imagine within the Swiss Cheese style. It says that most effective when the holes of the entire slices of Swiss cheese get aligned, then most effective an twist of fate occurs,” the professional mentioned on situation of anonymity.

“It’s only a metaphor. The Swiss cheese has lot of holes. Should you put slices of Swiss cheese in a string and spin them, there will probably be one in 1,000,000 instances that the entire holes can be aligned. That will probably be a precursor to an twist of fate,” he defined.

The professional mentioned the explanations for the crash may just come with environmental issue, human issue, technical issue, well being of the airplane, administrative issue and exterior issue like what the air site visitors controller is telling the pilots.

He mentioned a unexpected gust of wind resulting in a fallacious resolution by means of the pilots, situation of the airplane, fallacious signalling by means of the tool touchdown gadget or natural human error may well be one of the most causes for the crash.

“It may be a a couple of causes. We can not speculate. Wind velocity can be a explanation why. If you end up at low velocity, you might be at risk of have an effect on of the wind. One gust of wind can play havoc,” he defined.

The runway 10 on the Kozhikode airport is roughly 2,700 metres lengthy. The airplane touched down roughly 1,000 metres from the start of runway 10 whilst touchdown, in line with the AAI.

Captain S S Panesar, former director of flight protection and coaching on the Indian Airways mentioned the pilot will have to have diverted straight away to one of the most close by airports like Trivandrum or Bengaluru after he didn’t reach its first try to land on runway 10 in unhealthy climate situation, the use of the tool touchdown gadget (ILS).

The ILS makes use of radio beams to present pilots vertical and horizontal steerage whilst touchdown the airplane.

“The government have discovered the DFDR (virtual flight information recorder) and CVR (cockpit voice recorder), however something will stay unanswered, that why did not he divert?” Mr Panesar requested.

The mavens mentioned the flight information recorder would give the investigators situation of the well being of the airplane, whilst the cockpit voice recorder will supply main points of what the pilots had been pondering and what they had been going thru ahead of the crash.

Captain Deepak Sathe used to be the pilot-in-command and Captain Akhilesh Kumar used to be the primary officer of the flight AIX1344.

In step with the AAI, the visibility at Kozhikode airport when the flight landed used to be 2,000 metres.

The Kozhikode airport is a CAT-1 airport the place flights can land with visibility of 801110 metres or extra. At a CAT-IIIB airport, the runway visible vary can also be as little as 50 metres.

B737 is likely one of the most well liked airplane fashions of Boeing. In step with the airplane producers’ operations handbook, a B737 airplane can satisfactorily land or take off when the tailwinds don’t seem to be greater than 15 knots.

A former DGCA reliable informed PTI that the twist of fate will have been avoided had the runway been prolonged some extra throughout the previous few years.

In 2017, the AAI had tried to acquire land to increase the runway, however it used to be now not ready to take action because the land acquisition used to be proving to be dear and there used to be stiff resistance from locals, mentioned the reliable.

Addressing the questions about runway 10, Civil Aviation Minister Hardeep Singh Puri mentioned on Monday the airport is provided with Runway Finish Protection Space (RESA) as in keeping with World Civil Aviation Organisation (ICAO).

Ten years again, an Air India Specific airplane overshot the desk peak runway at Mangalore airport, fell right into a gorge and stuck fire, leading to lack of 158 lives.

Pointing to the similarities between the 2 injuries, Mr Ranganathan mentioned “if the similar error is finished by means of the similar airline (Air India Specific), so what came about to protection audits and different assessments that the DGCA has been doing for the remaining 10 years”.

Mr Panesar mentioned there will have to be a judicial enquiry into the twist of fate as it is going to permit aviation mavens to record affidavits and ask pointed questions in regards to the twist of fate.
