Asiana Boeing 777 crashes in San Francisco

I was an ILS tech in USAF, I keep hearing it was out due to construction. I don't understand that, the antenna and equipment is located right next to the runway at the touchdown point. The runway should be closed if work is that close to an active runway.

The runway threshold had been relocated so the glide slope was not correct for the new touchdown spot. They were in the process of realigning it so it was NOTAM'd out of service as was the PAPI.

Cheers
 
- .. I wonder if UA will reimburse any of the expense. ...

Really? Why would you wonder that, is it somehow UA's fault you were delayed??

Ah, gotcha. How long is the relocation downtime, I'd think they would install a new one and switchover seamlessly like IT systems. Surely they aren't moving existing equipment.
 
A friend of mine also highlighted that the 777 PW FADEC has been caused some issues in the past. Including the BA accident.

Asian airline pilots are noted in the airline world for poor ability to hand fly to a landing and too reliant on automatic systems. Large airplanes like the 777 are very tricky to hand fly and require a good deal of skill.

Off center-line, unstable approach, steeper than usual glide slope plus other factors are not indicative of a mechanical or avionics problem, especially since there was no notification of a problem prior to the crash.

Cheers
 
Whole lotta speculating goin on here. Just curious - how many of you posters here are pilots? And, what type of aircraft do you fly?

Exactly. This is the type of freak incident that you need travel insurance for. You may not be on the plane that had the issue, but the financial fallout and inconvenience can be costly.

I feel like we're in that hotel commercial . . . "I'm not a pilot but I stayed in a Holiday Inn last night."

That said and all kidding aside, because the situation is very tragic, for most casual observers and frequent fliers, it doesn't seem to require a PhD in aviation or 25,000 flight hours to make some pretty basis assumptions on what reports have been in the media to include photos and eye witness accounts.

I pray for all of the passengers and crew, and their families. I hope the loss of life does not go up and that those who have been affected will somehow be able to survive to live a normal life again.
 
Actually I am a pilot- of small aircraft with one little ol' fan on the nose. And as I said back in #13, any speculation as to the cause of this crash is just that. Speculation. The NTSB, Boeing, Asiana, Pratt & Whitney, and SFO officials will all be involved in ascertaining the cause. Not us.

Be thankful there was as little loss of life and injury as there was. I'd put that fact in the 'near miracle' side of the ledger.
 
I'm not a pilot. I worked at an airport for four years maintaining the instrument landing systems. I'm more interested to know why it was off.

If it helps, think of the glide slope as a tractor beam that the plane can lock on and land itself. Even if its not locked on the pilot can rely on it to make his own adjustments.

I had a 30 min response time when it went down, it's a critical safety system.
 
As my Avatar may indicate, I am a pilot. Almost all of my flying is in small single engine prop planes but with some stick time in military jets from the T-39 to the F-14 as a Chief Engineer in the USAF for various airplane and engine programs.

Speculation abounds about the cause but based on my thinking, the most likely is pilot error. But just about anything can and does happen in airplanes, except some of the screwy 911 ideas. :rolleyes:

That is a pretty large brush you are using. This article does not get into whether pilots are reliant on automatic systems but a number of Asian airlines are listed as amongst the safest in the world. http://www.ausbt.com.au/new-website-rates-world-s-safest-and-most-dangerous-airlines

Tom Palm is an airline pilot.
 
CNN just showing a video from a man who was taping planes taking off and landing. Shows the actual crash from across the water. Looks like the tail hit the seawall.

Yes - that was established immediately.
 
From the NTSB press conference, it sounds like it was pilot error since the speed of the aircraft was significantly lower than what it should have been. One of the crew members called for a go-around and also to increase speed. Since I know NOTHING about flying, is my interpretation correct? The person who took the video said that he heard the engines rev trying to increase speed and thought the pilot was trying to abort the landing.

Low speed could have also been caused by a mechanical problem, so I don't think we will know for sure until the investigation is complete.

Haven't heard that from any of the experts. Are you a pilot?

Both 777 frames that have been written off were on final and had minimal loss of life. BA we now know was due to condensation in the fuel and long distance high altitude flying. Asia to UK. Again this is a 777 with the same engines that had just spent many hours at high altitude. Management and dispatch want to keep high to reduce fuel burn flying in the thinner air.

Wonder if this was pilot error, remember the BA pilots were initially blamed, or similar circumstance?

No I'm not, but that's exactly what the experts on CNN have been saying - That it's too early to know what the cause is - it could be pilot error, or it could be a mechanical problem. They won't say until they finish their investigation.

I spent 17 years as a Navy Pilot flying the P-3 and three years flight instructing in Pensacola in the T-34c. My ground job for 12 years included being the Naval Aviation Safety Officer at different squadron and also was in charge of ground safety for maintenance. Training included all the Navy safety schools including the five week school at the Naval Post Graduate School in Monterrey, CA. After the Navy, I flew for Hawaii Air Ambulance in the C-414 for one year and Aloha Airlines for eight years in the 737-700,800 NG ETOPS operations to the west coast. While at Aloha, I was Chairman of ALPA's Central Air Safety and Training Committee council 80 at Aloha Airlines. I attended all the ALPA safety schools including the five day basic accident investigation school. After Aloha Airlines shut down, I spent about one year flying the 737-800 in Japan for Skymark Airlines. A lot of my Aloha Airline friends took jobs in China, Korea, India, Africa and South America. When I worked in Japan, the Captains I flew with were Expats from all over the world. The First Officers were all from Japan.

I concur that we need to respect what happened here. The pilots flying this aircraft are human too and will have difficulty moving forward with the rest of their life. In one case I know about, the captain committed suicide after he ran a DC-10 off the end of the runway in a heavy rain storm in the south pacific. In this accident there were two deaths and a lot of injured that will suffer as well as the families of the injured and the families of the pilots.

A lot of the things mentioned in this post are contributing factors that the NTSB will state in their report. The ILS glide slope is used as a back up and not needed for a visual approach. Maybe they will recommend things like that get repaired faster. Maybe they will say heavy aircraft are not authorized to shoot an approach without it unless there is no other available runway. The runway has markings for the touchdown zone that the pilots could easily see and the ILS or PAPI was not needed. But, if it had been available and the pilots used it, the aircraft would not have been low on final. A video on TV that I just saw about 6 p.m. EST showed that the plane was low on final for the last segment of the approach. Possibly they were shooting a non precision approach where the aircraft descends to minimum descent altitude like 500 feet after passing the final approach fix (about six miles from touchdown). I am not familiar with approaches to this runway, but if there is a non precision that allows this, being at low altitude for the last few miles is authorized. The pilot is supposed to hold that altitude until he gets close to the runway. However, the news also reported that the aircraft was slow and that engines were at idle. However, just prior to touch down, the pilots were adding power prior to impact, but it happened too late.

There were four pilots on-board, so they should have been rested, but possibly lack of sleep and other human factors might be contributing factors to this mishap. The Navy and the FAA have a program to identify safety concerns. Pilots are supposed to make a report anytime they have an incident that could have caused a mishap or report any hazard they see during the operation of their aircraft. If the pilot makes a mistake and reports it to the FAA through his company, the FAA will not prosecute that pilot for making a mistake. The written reports go to the chief pilot and then the FAA. The purpose of the report is to learn from them and establish new procedures so that the bad situation doesn't happen again. As a part of the safety team, I read all the reports that were submitted in the Navy and at Aloha Airlines. Unsafe things happen way more often than most people realize. Things like near mid air collisions, ground collisions, almost landing at the wrong airport, falling asleep in the cockpit, tail strikes, hard landings, forgetting checklist, etc....

Because of the FAA and FARs, the major carriers in the United States are the safest airlines in the world. Additionally, pilots have to work their way up to get hired at a major. Only the best pilots with the best training work for Delta, United, American, or any of the other big airlines in the USA. I only state this so that the next time someone is thinking about saving $100 on a foreign carrier instead of flying a major carrier, they should know what they are buying.

This mishap was close to being a safety report. It is unfortunate for the pilots, crew, passengers, families and all involved. We can only hope that things change so it doesn't happen again.

One thing that has always bothered me is that pilot error is used as a cause way too often. One of the first accident reports I read was a P-3 crash in the Philippines in 1980. The aircraft had a catastrophic engine failure climbing through 20,000. The explosion of the #3 engine knocked out the #4 engine. It also caused a chips light on the #2 engine. The plane was heavy dumping fuel all the way back to the airport and trying to land in Cubi Point. The approach was around midnight in a heavy thunderstorm. When the pilots lower the gear about five miles from touchdown, the aircraft did not have enough power to stay on glideslope and ended up crashing into the bay about a mile short of the runway.

The investigation report stated the cause was pilot error. Most of the pilots in the Navy would not have been able to save that one. Pilots always get the blame. It goes with the job.

Microburst? Windshear?

Let's wait a bit. We will learn what happened here. And, it will be accurate.... unlike Flight 800.

==================================================
What you may be trying to communicate is that media, and JQ Public are too quick to state "pilot error" in these incidents, until all the facts are determined. I can appreciate your feelings.

With all due respect to your example above however, a data point of 1, the largest percentage of aircraft incidents are attributable to pilot error. If you have data that proves otherwise, please, do share.

I will be attending the annual EAA Airventure Fly In in several weeks. If one were to poll the thousands of pilots in attendance, I'd be willing to bet they would accept that cockpit error is the source of the majority of incidents.

In the case of this flight in San Fran, we'll just have to wait.

Wind shear perhaps? Pilot error? A combination of the two? Neither? We'll soon learn..
