Airport landing system off when plane crashed in San Francisco

A navigation system that helps pilots make safe descents was turned off at San Francisco airport on Saturday when a South Korean airliner crashed and burned after undershooting the runway ...

The system, called Glide Path, is meant to help planes land in bad weather. It was clear and sunny, with light winds, when Asiana

...

San Francisco International has turned off the system for nearly the entire summer on the runway where the Asiana flight crashed, according to a notice from the airport on the Federal Aviation Administration's Web site

Somewhere else in the thread he also explains it is down because of work on the runway. He is a B-777 pilot .

That’s not what the article said. “Glide Path is a computerized system based at an airport that calculates a plane’s path of descent and sends it to pilots in real time.”

That's what the article says. But, it's Reuters, and I wouldn't be the least bit surprised if they got it totally wrong.

I'm an instrument-rated pilot, and I've never heard of a "Glide Path" system. But, it's been a while since I've flown in the cockpit, so I may have missed it.

I've done a quick look on the web, and haven't found anything about it, either.

Besides, if the ILS was off then they wouldn’t be able to make evening and night landings after dark at that airport.

An ILS isn't required to make a landing at night. It's only required when visibility is limited. SFO 29L has (or had) a 4-light PAPI, and it would have provided all the guidance that was needed.

Is “Glideslope” different from ILS?

So what? The pilots were responsible for establishing and maintaining a proper landing glide path. They obviously blew it, unless the black box shows some equipment malfunction. It was a long runway, they should have figured the landing point some hundreds of feet down the runway, not the seawall.

“thats total bullshit!!!!”

Are commercial a/c allowed to land VFR at night?

Absolutely!

The Glideslope (GS) is PART OF the ILS (Instrument Landing System).
You can download the approach plate here.

BTW, have you considered switching to decaf?

I think you are over your limit on use of exclamation points. :)

However, I just looked up the airport info for SFO 29L. It has a 4-light PAPI, or at least it did if the plane didn't slide over it.

So, basically this is analogous to "calling the ball" optical system for carrier landings. Sounds like this plane did the equivalent of a ramp strike.

Both the PAPIs and the Glideslope were NOTAMed off due to the displaced landing threshold.

That's interesting: I didn't check the NOTAMs.

Did they just move the threshold? I'm surprised the PAPI's were off.

Don’t airports have LIGHTS to make visual night landings possible?

If this is the runway that comes in over the water, the pavement starts soon after land starts. I heard some news show this morning that the landing zone is about 1,000 feet into the runway, and the seawall is another 300 feet back from there, which means that the seawall is about 1,300 from the desired landing area.

So how far is a 1/4 mile when you are at landing speed? At 30 MPH, my GPS starts "turn here", and my GPS is in my car, which is on the ground on pavement, not in an airplane holding 100's of people.

This most likely is pilot error, but that approach should provide as much support as possible. It's not like you come in short and bounce in a corn-field and knock down a traffic sign; here you hit a wall. Big difference.

What with the sequester and all.

Yes, that's correct. There are a couple of different light systems used by the FAA. In the picture you posted, the aircraft is just slightly below the glideslope, with 3 red and 1 white.

However, another poster has noted that the PAPI was NOTAMed out of service.

All these ‘pilots’ here are certainly a bunch of rude a$$wipes aren’t they?

“The Glideslope (GS) is PART OF the ILS (Instrument Landing System).”

Then the description in the article was incorrect (big shock).

Does 777 have the Automatic Landing System?

Waaaaay Back when I took flying lessons, my instructor taught me the following on VASI lights..”Red over white, you’re alright, white over red, you’re dead”.

One of those things that just sticks with you.

I think you are as accurate to any assessment made. Losing the tail on the jetty is a very alarming angle to touch-down.
