There is a 50/50 chance of the pilots forgot to deploy them by negligence which I doubt it, because of checklists on every phase of the flight or an isolated fault in the hydraulic system. If the second is the actual problem ATC gave the pilots maybe the longest runway to be able to stop at secure taxi speed. Let's think a moment instead of judging something/someone, at the end of the day we weren't there to see what's actually going on.
The reason why he did not deploy them early enough is because, The Captain is trying to go from POINT A TO POINT B in the airport His Apron was probally guessing at the end of the runway. So he deployed the spoilers while he was going closer to his Apron so he had more speed to go their.
The plane bounced on landing. The spoilers are set and armed before landing. Until the plane is stable on the runway, they will not deploy. The reason for the delay was just in case they had to go around. Once stable the spoilers deployed. The aircraft also has fantastic brakes and 4 engines with thrust reversers.
I have an answer. During landings, the sensors on the landing gear need to make sure the landing gears touch all the way down, in order to activate the spoilers. This plane probably landed so smoothly, and that the landing gears were kept up in the air. Eventually after the planes main landing gears fully made contact, the spoilers deployed.
@15chad15 Isn't this a near direct quote from the text, Multi-engine Operations in Five Easy Lessons by Capt. E. Fudd of Looneytunes Airways? I used that book to help me operate my blender.
Spoilers usually are being deployed automatically. But in some cases, for some reasons, such as very soft landing, spoilers are not deploying, then PNF should deploy them manually.
Good question on the speed brakes - it's United, but it was at least a full 20 seconds after TD that the brakes were deployed..... guess they depend alot more on the reverse thrusters and wheel brakes
I dont think he forgot to deploy the spoilers because his nose was not on the ground, the second the nose hit the ground he deployed them, I think, it took a while before his nose hit the ground in fact I thought he was flaring until I saw the spoilers deploy :) I could be wrong
Well considering there was not much fuel left in the tanks, the guys up front forgetting to deploy the spoilers was just a mild mistake from protocol. After all the plane did not weigh much when it landed on the ground. About 300,000 pounds lighter once you landed into Sydney with some fuel reserve still left.
No really, didnt need to use speed brake early until a certain point to get to ther exit faster. But u do make a good point. I was just letting 'effective3 knw'
maybe the pic forgot to set it to arm, and when he's going to idle the throttle just before 80 knots, he realized it. though, spoilers are more effective at higher speed.
Looks like they forgot those spoilers, if the aircraft was so light that could have also caused some problems with the aircraft not settling on the runway
Captain: "Oops hope nobody saw that" I actually have seen AA 757 at San Jose landed and slowed down completely without spoilers, I can't find the video anymore but an accident had occurred because of a combination of failures including forgetting to arm the spoilers.
The spoilers are for loss sustentation over the wings so if you deploy spoilers to landing aproach u probably kill some people on the plane, you deploy the spoilers to transfer the charge over the wheels, insted the wings, to reduce the chance to skidding during the braking.
In some circumstances there will be no need to deploy spoilers. I'm guessing that the terminal was literally at the end of the runway and there runway length was about 8,000 to 10,000 ft. Therefore retardation should kill the speed.
+Scott Haysom The spoilers (and speedbrakes) have been armed, except the crew made such a smooth landing, that the sensor in the landing gear wasn't exactly sure if the aircraft had, indeed, landed. Only just before they deployed was there enough weight to deploy them, as the aircraft was still 90% flying.
+Scott Haysom I have a feeling that the 747 has a weight on ground switch on its nose gear, which looking at the flare angle, only touched down further along the runway. They wont have forgotten I dont imagine as the speedbrake arming is mandatory on the 747's procedures.
Don't worry, your not dead, don't report this to the media, the government, the federal courts or to us, I think we can let this scandal go just this one time ;)
@mobilemonkey625 LMFAO...I was being sarcastic too...lol-i like that one about did soemone shit in my cheerios...all technical mumbo jumbo shit was fuckin funny....have a good one 15chad15...ha ha ha
Your all wrong, With my Aeronautical degree from harvard and over 8000 hrs in the 747 cockpit. When reaching the outer marker and setting up the approach you SOP the spoilers to make them ARQ this way if there is any INOP the will override the redundency systems to make them AFLAC. This is text book. Now on landing you transverse the reverse thrusters this will make compression ratio drop to allow the AFI to activate when nose gear touches down. You need to go over your training manuels again!
After that flight I would go straight up to the captian and get a answer of why they did not deeply the spoilers because 6 years ago there was a major crash at JFK because the spoilers were not deployed
@sssoaring2 Sorry Melbourne is so much better than Sydney & It's airport (domestic & International) terminals are in the one building unlike Sydney where you have to travel between 2 buildings, Another advantage of Melbourne airport is that it operates 24 hours a day where Sydney can't because of people's complaints over aircraft noise. There is so much more to do In Melbourne than Sydney we have been voted as Australia's number 1 city & our state capital has always beaten Sydney.

Fascinating!!! Great inflight arrival .. your footage has been spotlighted on airliners net
if you look carefully the nosewheel touches down very late which could be why the spoilers waited
The reason why he did not deploy them early enough is because, The Captain is trying to go from POINT A TO POINT B in the airport His Apron was probally guessing at the end of the runway. So he deployed the spoilers while he was going closer to his Apron so he had more speed to go their.
Great video, this made me feel like I was on the plane :)

Exactly
sydney is an awesome city. the awesomeness slows down the aeroplane without the need of any spoilers :P

yes indeed, in 1999 AA flight 1420 from DFW skidded off the runway in Little Rock when the pilots failed to arm the spoilers on a wet runway

@dual757 Spoilers are armed during approach for them to be automatically deployed during touchdown.
I dont think he forgot to deploy the spoilers because his nose was not on the ground, the second the nose hit the ground he deployed them, I think, it took a while before his nose hit the ground in fact I thought he was flaring until I saw the spoilers deploy :) I could be wrong

nice landing its standerd procedere for the spoilers not to deploy on a long runway with a light load
Your joking right..? United airlines, if you didnt know off the winglet they even said it in the voiceover
No really, didnt need to use speed brake early until a certain point to get to ther exit faster. But u do make a good point. I was just letting 'effective3 knw'
very good video. pilot dont need to arm speed brake becuase the runway is long.
spoilers are on the check list also are armed whn the nose gear is firmly locked and on the ground
and sydney airport's runway 34L is pretty long
very clear
Haha. Loved it when he/she finally realized about the spoilers. Bit late for them :P Derp
do you know what runway you were landing on?
@mobilemonkey625 ...... thanks dude.
@MsLeesan lol now your catching on, but you got it wrong my flight instructor was Fred Flinstone.
Bit hard to tell but i think i saw 3 landings before the spoilers deployed
You don't always need to deploy spoilers,
Bob Job
You know the people who are aviation experts know everything. You summarized it in one short and factual statement.
Yes you fucking well do. Is that a short enough statement?
maybe the pic forgot to set it to arm, and when he's going to idle the throttle just before 80 knots, he realized it. though, spoilers are more effective at higher speed.

It was a smooth landing but a short stop
Be nice everyone - we are all friends here :)

the plane bounced twice.
some times they don’t need SPOILERS BECAUSE THEY can in SLOW
@15chad15 *manuals
Why the spolers took that long in deploy??????
Runway 34L
Yea - LAX to Sydney. United.
@UmarKhabeesKutta ,,,, I know Im not knucklehead I was making a joke to all the previous comments. Wow some people have no sense of humor.
Mmmm yes, didn’t see ANY spoilers deployed on that wing! 🤔
Finally, someone gets the joke.
@cessnaclub ,,, lol, finally someone who gets my joke.
serious error for the pilots you where flying that plane they didn't arm the spoilers!!!
I see deployed spoilers.
????
Airbrakes

Looks like a pretty normal landing to me.
except for the spoilers ;) they should deploy when the plane touches down :)
airbus343X Yeah, but that's at the pilots discretion and depends on speed, wind, traction . I've seen it many times and......tadaaaa...still here. :-)
Haha ^^
??? I can see 5 spoiler tabs in this video all in the correct upright position as they should be upon landing.
Click bate. Spoilers and reverses???
The wing looks dirty.
@mobilemonkey625 LMFAO...I was being sarcastic too...lol-i like that one about did soemone shit in my cheerios...all technical mumbo jumbo shit was fuckin funny....have a good one 15chad15...ha ha ha

Can you send a link of that
No you wouldn't...

casperblackcat1975 ah yes Melbourne. That’s one of Sydney’s southern suburbs, isn’t it and Tullamarine is Sydney’s 24/7 second airport?
Ahhh ok if u say so......go bid for another olympics if its so great.
came from airliners. (dot)net
@angeloedades,,,, lol, thank you I guess my fake aeronautical degree from Harvard didn't cover spelling. lol
You dont's understand sarcasm quickly do you
15chad15. You say you have an aeronautical degree yet you cant even spell properly. I hope im never on one of your fantasy flights
Ah yes... Harvard, but can't spell "you're" nor "manuals"
Gotta love these jokers. ;)
total bullshit. you did not go to harvard
