The ILS. Not needed in good weather. Pilots land all the time using visual. This pilot had to be able to land that plane without ILS.

Not every runway has ILS.

The cockpit voice recorder of Asiana Airlines Flight 214 appears to show the pilots attempting to abort the landing just 1.5 seconds before it crashed at San Francisco International Airport, the National Transportation Safety Board chairman said Sunday.

The pilots appear to have increased speed 7 seconds before impact, and they then "called to initiate a go-around 1.5 seconds to impact," Deborah Hersman said.

The NTSB's preliminary assessment of the plane's cockpit and flight data recorders show the flight was coming in too slow and too low, but Hersman stopped short of pinning the blame on the pilots.

...

The ILS integrates with the aircraft's cockpit to trigger a audible warning, consultant and retired 777 pilot Mark Weiss told CNN. "You hear a mechanical voice that says, 'too low, too low, too low.'" The ILS is "nice to have," Weiss said, "but it's not critical on the 777." There are redundant systems aboard the aircraft that would provide similar warnings if the plane was coming in too low, said Weiss, who has landed 777s hundreds of times.

Weiss said he's perplexed by the details surrounding the crash landing. If the pilot was somehow unaware the plane was coming in too low, Weiss wonders why another member of the flight crew didn't speak up and warn him.

The pilots at the time of the crash were Lee Jeoing-min, and Lee Gang-guk.

From the twitter stuff on NTSB site

The throttles were advanced a few seconds prior to impact and the engines appear to respond normally.

The data indicate that the throttles were at idle and the airspeed slowed below target approach speed during the approach.

FDR contained 1400 parameters and captured the entire flight.

Preliminary results revealed: 24 hours of recorded data.

An initial review of FDR data was conducted.

Call to go around made approx. 1.5-sec prior to impact.

Sound of stick shaker began approx. 4-sec prior to impact.

Target speed for the approach was 137 knots.

The flight was cleared for the visual approach to RWY 28L, which is confirmed by the crew.

IF the pilots tried to abort, can that cause a further drop of the aircraft?
