Why did the pilot in charge fail to recognize that he was going to undershoot the runway and did not abort the landing and go around?
Did he follow the PAPI (two white and two red) in adjusting his glide path?
From reports, the pilot at the control during the crash was was still under training on the Boeing 777. He has only clocked about 43 hours on the plane although he has been to this airport 29 times in the past but on different planes. His instructor who is new as a trainer has about 3220 hours and is therefore experienced on the plane.
It is not clear why the experienced instructor pilot did not take over to abort the landing. It is a standard procedure for all pilots to commence a go-around by 500 feet if the plane was not stabilized.
In most airlines, it is standard practise to have the other pair of relief crew to be at the jump seats during the landing as they are the additional pairs of eyes that can also monitor the safety of the flight. Some airlines even allow the pilots on the jump seat to initiate the ‘Go-around call’ if they are of the opinion that the flight was unsafe.
As the glide slope of the Instrument Landing System was not working, his next best guidance to stay on the correct profile (2 white 2 red lights) was the PAPI (Precision Approach Path Indicator). Obviously it was not followed by the pilot or else he would not have hit the seawall.
However, the spokesperson of NTSB which is responsible for finding out the cause of the air crash, said: "I think it really is too early to conclude pilot error because there's so much that we don't know."
The NTSB had said on Sunday that the plane was "significantly below" its intended air speed and its crew tried to abort the landing less than two seconds before it hit the seawall in front of the runway.
On Monday, fresh details from NTSB stated that “the plane was flying at just 119 miles per hour immediately prior to the accident, a full 25 percent slower than normal for the descent."
Also, the flight data recorder indicated that there were no signs of trouble until seven seconds before impact, when the crew tried to accelerate.
"A stall warning sounded four seconds before impact, and the crew tried to abort the landing and initiate what's known as a "go around" manoeuvre just 1.5 seconds before crashing.”
