JAL incident at Haneda Airport

[krismiler]

Possibly a runway incursion by the coast guard aircraft, a clearance to line up behind being misunderstood as line up. If the coast guard aircraft was high wing they could have had difficulty in seeing an aircraft approaching from above. The JAL aircraft would have been in a nose up attitude which would have restricted their view, and being night time, all the holes in the Swiss cheese lined up.

I haven’t operated into Haneda but the complexity of the taxiways at Narita was certainly memorable.

AVHerald reporting that there was no command to evacuate. "A first announcement was made "please calm down" followed by "do not take your luggage and do not stand up". There was no clear announcement to evacuate, however, when other passengers stood up they also stood up and thus escaped." Avherald

Yes, C1-C11 on that side of Terminal2

On ground movement maps for RJTT, the four runways are designated according to the corresponding taxiways letters, A, B, C, and D - 16L-34R being depicted as "C-RWY".

Whilst not criticising the passengers - I am not there and certainly not in a position to know the circumstances - some of the images do show what seem to be mobile phones "on" and in some cases "deployed" by the passengers. I wonder if they used the flashlight function [cabin dark?] or where they tempted to memorialise things? Or both, of course.

The ambient lightning outside of the acrft doesn't seem to require trhe use of additional mobile phone lighting in any case. I know in my personal case, I'd take longer to swipe to the damn function for it to be of use in an emergency situation.

This link has a video from inside the aircraft.

DHC-8's usually disappear from both FR24 and ADS-B Exchange once they get below around 2,000 feet, it's something to do with the transponders they have.

Just for reference for those discussing tracking the coastguard aircraft, searching the reported registration of the aircraft involved (JA722A) shows it arriving into Haneda 21 hours ago, it also shows that it is tracked via MLAT, with the last tracked position being just before the runway threshold.

I've copied this from multilateration.info describing how MLAT works:

• "MLAT ground stations receive replies from all transponder-equipped aircraft, including legacy radar and ADS-B avionics, and determine aircraft position based on the time difference of arrival (TDOA) of the replies."

This generally requires (I believe) at least 3 or 4 receivers intercepting replies from any aircraft to be tracked so MLAT tends not to work very well, if at all at ground level.

From that information, providing the reported registration is correct we can assume that the aircraft was not broadcasting ADS-B data, would only be able to be tracked via MLAT and therefore there is no publicly accessible tracking data for it on the ground.

Which actually might be the same amount.

At least one of the publicly available videos shows dark smoke in the cabin. In general the flow of people through bottlenecks is best achieved without haste, thus there would be time waiting for pax in the queue.

As everyone got off alive I suggest that the form of learning here can take the form WWW/EBI - What Worked Well/Even Better If

At approx 17:29 (0847z) of that ATC audio, there are crackly remnants of a line up and wait instruction/read back. Can't tell for which runway or aircraft its relating to, but could be pertinent in case anyone has access to better audio/ears than me

Well this seems like another well handled evacuation from a professional crew which reminds me of another crash where all escaped thanks to the crew of the Air France Airbus 340 in Toronto many years ago. Many people are alive today thanks to this JAL crew.

This is tragic. A member of the public can see aircraft movements on FR24 and spot a potential collision before any onboard aircraft systems and ATC can. How is that possible in 2024?

Slide deployed properly, but since the nose gear collapsed during the impact with the Dash, the tail is higher, so the slide is in a steaper angle.
There is no collision warning system on the ground. As soon as you touch down, those systems switch off. How would you navigate on the ground otherwise?

Well it's pretty non scientific but using FR24 I've had a look at a few random recent JL516 arrivals in to HND and for northerly arrivals they've all been on 34R, not seen a single L, I'd say I've looked at 12-15.

Ambient/Emergency Lighting in aircraft is somewhat worthless when you're surrounded by opaque grey smoke and pungent choking fumes. Passengers would be in a panic mode and making rash decisions in difficult circumstances, some suffering with smoke inhalation and shock. Possibly separated from other family on the aircraft who may have disembarked from different chutes and looking to contact them in the hope they got out alive. When safely a distance away from the aircraft, taking a 'trophy snap' of the raging inferno they just survived seems kinda reasonable all considered.

I’ve thought about this for a long time. I flew Ryanair in Europe once, 99% of the passengers were uni-aged kids and the emergency exit seats had been bought by an old couple. And I mean old. Like 80. So they clearly paid for more comfort whereas the kids wouldn’t. If something had happened they were the wrong people to have manning the exit. (I was in the exit row on the other side)

Don't be in too much of a hurry to judge by appearances.
I am 81. I flew 737's for 25years. I still give my full attention to the safety brief, in spite of all the times I did my safety training, and opened an overwing hatch for real. I suspect that I would be more likely to open the hatch in an emergency that a uni-age kid who did not lift his eyes from his computer game during the safety brief.

I'm impressed at how, with this damage, the A350 crew controlled the rollout and stopped on the runway, and equally impressed at how tough the A350 structure appears to be.

Apart from the A400M prototype this is the first burnout of a composite wide body that I'm aware of. Composite structure must have a different flammability profile to aluminium alloy, and I wonder whether that explains the firefighting approach?

could be. i remember years ago, when they were in development, there were discussions in my company about new risks associated with a 787 or 350 crash sites, such as toxic smoke as well as particles akin to asbestos iirc which could be released in a crash. unfortunately, i did not follow up on what the final verdict was on these health risks for survivers and first responders....

FR24's own blog about the event supports that interpretation.

Apparently, domestic flights arriving from North under Northerly winds land at 34R. See below and link.

One thing to note on the firefighting: The fire appears to be small, with the lonely 2 people extinguishing it from the front/back of the #1 engine, and then does appear to die down (around 18:21 local in the timestamp in the video below). However, then the fire comes back with a vengeance, and around 18:24:40 a third person appears and goes first to the firefighter in front, then to the one behind the engine, and seems to pull them away and tell them to abort. Don't they have radio contact?
