One of the most beautiful night sky I saw was in the night flight from Seoul to Hanoi. The colorful sunset and twinkling stars were all visible from the cabin window.
Yes. The engines are truly powerful. One underground complex in Seoul called 'COEX' uses only a couple of them (2 to 4) for ventilation in the entire facility.
Your comment reminded me to get in touch with my brother who is an aircraft engineer for B747s and a series of Airbuses. Anyway, the electronic devices that should be turned off are those that are being used by the passengers in the cabin.
Greetings Kiiiam. The film was taken by a friend of mine who flew with me to Frankfurt Am Mine. I was seated somewhere else. I just uploaded it for him.
while the "too much pressure" thinking is not wrong, the real reason is to take lift away from the wing to make sure the aircraft has firm contact with the ground. the slats are not used to slow the aircraft down but to change the airfoil (together with flaps) and create needed lift at slow speeds..such as during take-off and landing.
The Slats and inboard krueger flaps retract automatically on selection of reverse thrust to reduce the chance of an object being blown up from the runway and damaging them, and also to reduce the stress they experience when the thrust reverse airflow hits them. You will notice they extend again on deselection of reverse thrust, so in the event of a go around, the aircraft is still configured to fly. regards
B747-48E in service with Asiana since it's delivery. It's either HL7421 or HL7418 since they're the noly 744s that are either not cargo, nor high density M version. Hope that helped, oh and Asiana is reg. in South Korea I think too. Have a nice day! ;)
Dear Jemmy, thanks for your interest and reply about the short film. I just want to tell you that traveling abroad can be a wonderful opportunity to escape from boring everyday life. Just being left alone in a different culture, language, lifestyle is challenging.
If it were water on the runway, it would have come up from the #4 engine too. It comes out from the right side of the #3 engine only. If you watch closely, you will see some escaping in the exhaust before reverse thrust is deployed. It would have been a good idea to report it to the flight crew immediately after landing.
I'm afraid u r mistaken about the dust thing. When the airplane lands, The pilot engages the reverse thrust which - as it's name implies- Reverses the engine operation mode, By creating an outlet for compressed air in the direction of motion inorder to assist in the braking operation. And that smoke my friend, happens to be the compressed air which u dont normally see because it's main outlet is at the rear end of the engine( Nozzle).
@festusthefiend oh wow thanks for explaining that i alway notice that and wonder why tht happen everytime everytime they activate the reverse thrust and i notice also when there taking off also that it stays up for a while then a couple second it goes down to match the other flaps postion
Modern jet engines are basicaaly two engines. You have one engine where the fuel is burned. That provides power for the big fan at the front which generates most of the thrust with the rest being from the exhaust. Thrust reverse only redirects the thrust from the fan, not from the exhaust. As for standing next to a jet engine while its running. Not recommended, especially without hearing protection or special training. Some of the bigger engines produce over 3000 lbs of thrust just at idle.
well this was a beautiful land but a thing i dont like about the 747 is that it is so loud but the a380 has a ruff landing but it is more quiet than the 747 and also the a380 has a better first class and business class then the 747 so if i could pick to ride a380 or 747 first class for free i would pick the a380 i would pick it even pick it if it was even first class or business class

Reminds me of when I landed at FRA in an LH 330, a very smooth landing. You almost couldn't tell when it hit the ground!
Wow, such a smooth landing! First-rate piloting.
nice that someone actually knows what they're talking about unlike the BS that most people say on these aircraft/flying comments
this video reminded me how much i like my washing machine
the reverse thrust looks sick
I guess that is one way to dry a runway! Awesome Video thanks.

Thanks for the comments KJ0609. It was filmed by a friend of mine who traveled together to an industrial show in Germany.
Hi, guuu. I am a Korean living in the lakeside city of Chuncheon. A friend of mine took this clip. We were going to Dusseldorf.
Bingo, Fortesimo. They changed their logo, by the way. Time flies by. That film is already an year old.
Thanks for the comments. I have no knowledge on airplanes, but a year ago, someone said its rain water. It was a bit rainy that day.
those are some powerful engines!

Very nice video and reverse thrust at 0:28

Thanks Egyptian. I hope to make frequent trips to know the place as well as you do.
Very nice video! Great reverses
Asian carriers are well known for their sincere service. Korean, Asiana, Singapore are good examples.
Most amazing moment of the flight for almost every human.
wow 0.30 looks great!

very well done! great footage
love the landing !!
Approx. 15 hours from Seoul to Frankfurt and then to Dusseldorf. A pleasant flight actually.
Dear Chanm. Just checked your site. Nice background.
Dear Pavel. That is the status of the 747 engine during a landing.
he was actually right, alex. The reverse thrust makes the engine blow the water in front of it, not suck it up.
very smooth landing looked perfect, where had it come from. The reverse thrust looks awesome with the rain.
I shall remember that name. Frankfurter Kreuz. Thanks Conhopper.
Nice; perfect landing !!
Do the leading edge slats retract automatically when thrust reverse is applied?
ive always wonderd how reverse thrust works. does it change the angle of the fan blades or something?
great video!
Marvelous invention indeed!
Beautiful
exelente toma del sistema de frenado de turbina, se aprecia muy bien por el agua que hay en la pista, ¡muy buen video!.

yer but what changes the direction of airflow? when the cowling moves back? does that act as a like air brake? :S
fabulous..........well done....
Thanks for the comment. I would have never known the physics behind the phenomena until your explanation.
yes, but flaps (and slats) are not designed to generate drag. but it is a welcomed side effect.
Thanks!
Yes. It was slightly raining that day sometime in November last year.

Sounds like an interesting idea sonmin.
yep their new livery looks nicer but i still prefer the old one
I landed in this airport last summer :)
If it were water on the runway, it would have come up from the #4 engine too. It comes out from the right side of the #3 engine only. If you watch closely, you will see some escaping in the exhaust before reverse thrust is deployed. It would have been a good idea to report it to the flight crew immediately after landing.
yup i get it now, its like how a rudder deflects air flow to the left or right. insted it forces the air forward rather than back
It's not smoke. It's water. The runway is wet and the jets are pushing air in the opposite direction.
Pratt and Whitney's JT series Engines I suppose?
please can anyone explain why white smoke came out of the engine? and the disappeared?!
Thanks pilot 96732. I'll share the clip and comments with Asiana engineers.
Anybody know why the slats retract upon touchdown?

SMOOOOOTH LANDING!!!!
ah thank you for correcting, wasn't thinking
The reversers are fine,what your looking at is the engine sucking water or moisture off the runway.
thats a good landing
reverse thrust is only available once the wheels have touched down as there are sencors that trigger it
Dear Andrei, this flight is Incheon-Frankfurt.
True.. Thanx for the clarification :)
@antreaSallonika Reverse cannot be activated if you're not in ground
yepp, that's correct. Normally at a good weather, the final glideslope decent speed must be established at 170 knots.
Asiana, the one with the beige paint not the new one.

Thaaaaaaaaaaanks~
jesus christ i didnt think the wings flexed that much that is insane. i dont fly much
That was a soft landing!! Asiana airlines right? I can tell from the winglet. Nice vid
waht is this for airline
Very good observation. Asiana indeed.
Wrong sunshine! Its fan air! Its not compressed air, only the bypass air is directed forward, you still have core air being directed back!
Dear master, I have no technological knowledge for the engine manuvers. Although it wouldn't be too difficult for any aircraft engineers.
I see. Thanks EveningsGlory.
smoooth landing
Looks like Asiaiana?
was that water on the runway?
almost right :) it was the water off the runway being sucked into the intake before engines were throttled down
Very nice video, where this flight come from?
Scary isn't it? But don't worry. It is much safer than you think. Thanks for the comments.
Dear Joshun, thanks for the reply. However, the aircraft is B747.
Cool
where did you came from ?
cooooooool
oh nice how long was the flight ??
What airline is it?
aren't all electronic devices supposed to be turned off during landing?????
i miss coming to frankfurt
air france right?
cool
Asiana Pilots are didicated. Recently, one pilot even donated his liver to a colleague at work.
Yes. Spyko94. It was Asiana~. They have a different company logo (design) now.
Was that Asiana Airlines?
Thanks farmerbrown12.
well this was a beautiful land but a thing i dont like about the 747 is that it is so loud but the a380 has a ruff landing but it is more quiet than the 747 and also the a380 has a better first class and business class then the 747 so if i could pick to ride a380 or 747 first class for free i would pick the a380 i would pick it even pick it if it was even first class or business class
Dear Choi. COEX is the only facility I know.
it looks like water vapour though, i'm thinking that the runway might have been a bit wet, that seems to be the correct reason.
