I'm sure the authorities will look into this when writing their report.
I am almost certain JJA4 -
I'm not a safety ''expert'' but since commencing my career in civil aviation in 1971 all air safety its causes and findings immensely interest and fascinate me and I made it part of my work - I worked for BMA and knew the Kegworth skipper well.

and perhaps I had a lean towards investigative work who knows.....
hey ho but i was no good at maths or physics for a degree lol

If the aircraft on C were waiting to take off they would have been at the threshold end and clearly visible.

It certainly wasn't anything close to a disaster. An embarrassing, recoverable error if true, at most.
Huh? This looks pretty damn close to a disaster.

Adoption of Forward Looking IR (Enhanced Flight Visibility Systems, EFVS in FAA speak) and Synthetic Vision Systems (SVS) would go a long way to eliminating night visual problems. The EFVS view, especially in a HUD, would have shown the line up planes as four large signatures and the lighting clearer, assuming it hadn't been converted to LED. The SVS would have shown the runway off line-up to the left in a daylight view and the taxiway in front of them. SVS is good enough to show you taxiing across a runway and the view on the PFD or MFD is identical to the outside view.

The damn AC aircraft likely did not even have GPS.....

If what the report states is true, that the AC drivers did not even recognize the taxiway was full, that implies they did not see the landing lights, nor hear UAL 1. (or are not telling the truth) There is enough intent in their statement alone, (forget the lack of CVR data) to prevent those 2 from rotating again.

Time to stop making excuses for the airline, the ac, and the crew. Let DHS get the true story out of them.

The 320 in question did not have GPS but is that really an excuse for a VFR approach at night under good visual conditions?

Besides that, not having GPS, the FMS would have used DME/DME for updating which is extremely precise enough to get you to the threshold of a runway.

I totally agree...

What bothers me is the fact they allowed the CVR to be over written perhaps purposely to cover their mistake(s).

Then in there statement to the NTSB they claim they never saw any aircrafts on taxiway C, so why did the initiate a "GO Around" at 85 feet AGL if they absolutely thought they were landing on RWY 28R?

Sounds to me like they are covering up, in other words lying about the whole incident, if so they should to be fired.

Does AC have the authority to use the special "FMS RNAV Quiet Bridge" procedure? I've not seen anyone post that bit of info--maybe they don't.

Maybe I am wrong but I believe that is not the approach they were cleared for.

Yes, it is clear in the audio, requested and cleared for FMS Bridge Visual. Some call it FMS Bridge visual, others call it RNAV bridge visual , some call it simply 28R visual in the ATC tape. Pretty loose given there is a Quiet Bridge Visual and Tipp Toe visual to 28R.

They would have to have DME/DME/IRU in lieu of GPS. They would have had to have it in the FMS to be approved to use it. Both the airline AND the crew have to be apprved. It is commonly used, so it is likely they were approved.

The 320 in question did not have GPS but is that really an excuse for a VFR approach at night under good visual conditions?
The response was to someone suggesting that Heads Up would be in order, hence my response that the ac does not appear to have GPS, so it is unlikely the airline would have the wherewithall to provide HU capabilites.

I agree, that was not the correct name for the approach AC 759 was given. The mixed up name on the D-ATIS doesn't help matters in my opinion. Perhaps the Quiet Bridge Visual and FMS Bridge Visual approaches were verbalized correctly on the voice version of the ATIS.

From an earlier post:

This link will time out soon when it hits the 30-day mark so download the clip from liveatc.net if you think you might want to review it later.

Hold on a minute

Quote: various posters subsequent to the NTSB information release yesterday, professing various conclusions about crew acts or omissions, and consequences, relative to sanctions, and system component reforms, and even ... causation.
Forum 11th Commandment: Must Have investigation report and those odd, pesky things, known as facts.
There is just too much left to be uncovered by the investigation process, and then still too much needing to be done to integrate the various and several factual elements into a coherent whole picture of the incident, before many of the assertions being made here would be justified and warranted. True, compared to investigations a couple of decades or so ago, places like this forum provide lots of access to relevant information - all the more so with all the tech gizmos which can show position, time-stamp, and more. But the thread is not the investigation. And before ya'all throw FCOM books at me, just think for a minute: once the facts are indeed known and integrated into a coherent whole picture of the incident, there will be plenty, plenty of time and opportunity to discuss probably dozens of system and subsystem reforms and changes. Wasn't the point, or one of the points, of poster Ian W.'s tutorial on attentional tunneling, a/k/a target fixation, that this could happen to anyone manning the flight controls? But let's hang the crew on suppositions here, heck, it's just the internet.

Agreed 100% WillowRun 6-3.

Also, we know that post-incident/accident statements are often very inaccurate -- not necessarily because anyone is lying but due to natural characteristics of human memory. Hence the lack of the CVR recording in this case is a big loss for the safety investigators.

Perhaps it's time to mandate the 25-hr CVR rule worldwide.

Again, I don't believe AC 759 ever 'requested' this approach. They were advised to expect it on the ATIS, told to join it by a NORCAL controller and later cleared for the approach by another controller. At least that's what I get off the LiveAtc.net tapes.

Can you provide a cite that says otherwise?

Your earlier post claiming planes were 'requesting' the FMS Bridge Visual 28R from the tower controller is total nonsense in my opinion:

Interesting, when you listen (to the recording in post #4 of this thread) you hear different requests coming in.
at 1430 you have a delta request 28R visual;
at 1705 someone requests FMS 28R, bridge visual;
at 1942, a delta asks for RNAV bridge visual 28R;
at 2110, you have air canada 759 request FMS bridge visual 28R.

As an outsider with some knowledge of aviation this real issue is possibly clearer to me than to those closer to things. The AC pilots are surely fine pilots and representative of their profession. The guys in the waiting planes, likewise. But literally everyone was asleep here. The entire system nodded off. Why?

Routine. There is so little freedom of action, and the the long day is so overgrown with necessary actions performed almost as an automaton would, that given a certain hour of the day, condition of lighting, etc. the truth can hide in plain sight. That can't be a plane coming at me - planes don't line up on taxiways! They are for taxiing! And those runway lights sure look strange - shrug. Can't wait to get down and get some sleep.

So much of the visual stimulus at night is hard to make out, even if colored like a Christmas tree. It must seem a wash of pretty lights sometimes, moving with hypnotic slowness. Every pattern has a significance, but maybe there are too many of them to keep immediately in mind because you are tired or just bored after a long day being a part of the machine. There are numerous cases of "how on Earth did they not hear that alarm? Why didn't they set the flaps? How can you mistake a frequency for an altitude?"

I don't know what you can do other than to make life more interesting for pilots so that they remain engaged. Let them - no require them - to do some hand flying. That's a start.

jeeezus...listen to the tape...they requested clearance to land for that approach...correct, just like all of the others on the tape...what, you want me to type out requests clearance to land for each line? I simply typed requests, not requested as you are stuck on.
I guess you did not listen to the tape, or you would have understood what was meant....there you go....

The AC pilots are surely fine pilots and representative of their profession. The guys in the waiting planes, likewise. But literally everyone was asleep here. The entire system nodded off. Why?
The taxiway is very near the runway on an offset angle approach. While waiting in line (for what appears an extended amount of time due to 28L closure), you are staring out the windscreen trying to figure out if the other ac are on RWY?
How often do lawyers sue other lawyers?

Who were asleep, were the pilots in command of the AC jet.

As much as drivers want to claim they are solely responsible for the command of the aircraft, here is the chance to put blame exactly where it belongs.

Children of the magenta line make excuses for poor performance. As noted, there is enough intent shown by the circumstances to show that it was an accident. It should and likely will be treated as such, and the responsible ramifications should be followed through.

There are systems that warn, but the bottom line. no matter what the warnings, ATC instructions, or aircraft , it is the PIC that makes and takes the responsibility.
Bottom line, that crew drove the ac down the taxiway on a clear night. Bright and very adequate approach lights...and a big white 'X' on 28L.

"jeez, looks like there is something on the runway, but ATC says there is nothing, so I will land anyways. Oh , I forgot to turn off the CVR and it got erased...really, we dont remember seeing any aircraft on the runway, those bright lights shining at me, or hear the radio saying I was on the taxiway....we just remember seeing something odd, and decided to GA.... "

How did AC 624 A320 plow into the dirt 300m short of threshold?

FFS, make all the excuses you want...time to cull this herd, with good reason.

So now they are requesting 'clearance to land for that approach'?

de-Sitter,

I wont comment on the "probable" causes leading to this incident, lot of speculation as usual, except for that regarding the local time this happened and how long their workday/night had been so far tiredness might have played a factor. My experience(25yr ww) is that boredom usually doesn't show up on approach and landing(complacency maybe).

Maybe it makes you feel better knowing that plenty of pilots still hand-fly, usually at lower levels and the flight departments encourage it. This depends on the(expected) workload though, flying into a challenging airport, or just a lot of traffic, weather, tiredness etc or a combination of all, yes, it can get interesting..(SEQM eg)

Seems the only thing clear from this thread is who are pilots and who are not.

Why I asked about AC's approval is their are TWO Quiet Bridge approaches--one public visual and one private, by specific approval FMS Quiet Bridge approach. Is AC approved for the approval required FMS Quiet Bridge or where the actually flying the public visual approach?
