A380 Landing Short on Pax Video?
 
Some outfit called the Air Safety Group has posted a video of a 'nameless' airline's A380 supposedly landing short of the threshold. This looks like a seat back screen, after the touchdown a pop-up message asks 'How did we do?'

The video is being retweeted on aviation sites like @CivMilAir and will probably make its way into the news cycle on a slow weekend.


This video has been sent to the ASG it shows a serious incident of an ****** A380 landing short Would anyone with any information about this landing please send it to



One of the comments on the original post suggests that the touchdown is normal while the video is several seconds behind which seems plausible. I'd find it hard to believe that an A380 could land short without someone else noticing.

In my experience those cameras often have a several second delay. It's obvious when watching for rotation or touchdown as a pax.

Is the touchdown confirmed at the same time by both the video plus the sound? If so I don't see a several second delay.

Any chance for picture foreshortening?

But the sound is the ambient cabin sound, not from the video feed. You can hear the touchdown before you see it on the (possibly delayed) video feed. Makes sense to me, (if my brain is working this morning, anyway).

Personally, watching these video feeds as a pax on many flights, it looks normal to me. Maybe some IFE systems have more delay than others, but they are all delayed. Takes time to encode the video from the source and stream it to the IFE.

If they indeed touched down short they would have collected the last part of the approach lights which would have caused substantial damage to both the plane and the lights (!). Something doesn't add up.

Methinks that the somewhat pompously self-described "Air Safety Group UK" hasn't done their credibility any good by posting this nonsense.

Has anybody ever heard of this "voluntary effort to improve safety for the travelling public since 1964" ?

Check the vasi “all white”...

Yes much different perspective from the flight deck but a good cue to suggest nothing was amiss. I have had 8 sectors as a passenger on the A-380-800 and all landings have been firm........

But then again who am I to judge....

Replying to @ASG_EGTT @AviationSafety @avheraldIt’s not a serious incident. The camera video is delayed on all A380’s so the sound of touchdown is ‘live’ and the video on screen comes through after a few seconds.

DaveReidUK 26th Jan 2019 18:12

Tweet now deleted.

Hopefully the airline-that-cannot-be-named, whom they accused of landing an A380 short of the runway, will be understanding in this instance.

Wannabe Flyer 28th Jan 2019 10:05

So that explains why all tail cams not the 380 I have flown in the last month have been switched off on a large 380 inventory holder. On the first flight I thought might not be working but on the subsequent three flights they were also off....

Well you're half right. :O

I have the video, it's everywhere on whatsapp, I just don't know how to load it here but PM and I'll share...

sounded like one...

Jetjock330 29th Jan 2019 09:41

Its been investigated found to be a delayed video feed of a few seconds between real time reality and where it was 5 seconds before!

Morane 29th Jan 2019 16:13

the video clearly shows the name of the airline that can not be named

Doors to Automatic 29th Jan 2019 17:12

There was a very similar video posted ten years ago:


Touchdown at exactly the same point but on this one you can see the spot of the real touchdown when the spoliers deploy.

Intruder 29th Jan 2019 18:18

It is also quite possible that the runway had a displaced threshold, and the pilot landed on good runway surface, not in an overrun.

172_driver 29th Jan 2019 18:58

I like the "Thank you for flying Ethiad Airways, how did we do?" at the end of the recording :D

fatbus 29th Jan 2019 19:58

It appears normal . Move on !

Let me clarify a few things having previously flown the thing. That Sydney Emirates one is live video and that’s a undershoot. Just be thankful it wasn’t the other end. Spoilers don’t deploy at the speed of the 737 or A320, initial deployment is only 5 degree/sec.

I am not overly convinced the original discussion video is delayed either (AUH 31L). Whilst it’s very hard to see, I’m seeing handling characteristics of landing short.

mickjoebill 30th Jan 2019 01:49

One way of measuring the time delay is to simultaneously video and observe the beginning of push back or the arrival at the gate. Do this by Videoing the seat back display but observe the pushback through the window, when pushback starts shout now! so your voice will be recorded. Replay to examine the time delay between your voice and when the onscreen display reveals begining of pushback. Also works for the end of flight.

Agree. Much ado about nothing.

For the benefit of the rest of us here, what exactly are you seeing?

Ollie Onion 30th Jan 2019 03:30

Looked like a normal landing to me, just a delay on the video feed.

ManaAdaSystem 30th Jan 2019 08:08

Why would there be a delay on the video feed?

Have you ever flown an Airbus?

ManaAdaSystem 30th Jan 2019 08:54

No, but I know at what speed electrons move, and they don’t take 5 seconds from camera to screen.

DaveReidUK 30th Jan 2019 09:18

Haven't we been here before?

I'm not exactly sure that's the reason for the latency in rendering the video. ;)

Doors to Automatic 30th Jan 2019 23:33

I stand corrected. There is definitely NO time delay.

Take a look at this one.......


NWA SLF 31st Jan 2019 00:21

Is it possible they delay due to what happened to the American DC-10 in Chicago? If I remember correctly amounts awarded were higher because the passengers watched their crash from the front facing television. American removed these immediately after the accident. I'm not aware of anybody using them again until the A380. We should be able to look over the captain's shoulder just like in a taxi and us passengers give advice like are you sure you are taking the fastest route, watch out for the turbulence, etc.

Chu Chu 31st Jan 2019 01:30

One day last summer, I sat in seat 50H of an A-330, watching the downward-facing camera as we landed on pristine white concrete, with the the first isolated tire marks just coming into view at the top of the screen. I heard a few gasps, which seemed to be from passengers watching the same view I was.

I didn't think about video delay at the time, but that's the obvious explanation. (I remember that the touchdown came just as I was thinking that we were a few seconds from landing -- and I guess on the video, we were.)

George Glass 31st Jan 2019 04:20

The landing at Sydney on 16R was definitely short. The tire marks on the piano keys were there for months after. Sitting at the hold point watching landings in a gusty quartering tailwind or southerly buster on 16R can be entertaining. But no laughing. There but for the grace of God go I.........

Bull at a Gate 31st Jan 2019 04:29

Delay as an explanation for this video? I call bull. Videos of the view from the tail camera of a landing A380 are available all over the internet. Some show the view from the tail camera on a video screen, a pan to the window to see outside and then a pan back to the video screen. The two views, inside and outside, are synchronised. Try this one for example.


I agree with Doors to Automatic. There is no delay.
