Korean - a recent good landing!!

Boeing777 Good Landing? (http://www.youtube.com/watch?v=TKCoka6mPRQ)

at Narita

[Noel White]

Struth. :eek:

[Matt N.]

Jeepers! Now that's a wobbly bounce (or 5!) :eek:

[Jayden Laing]

So in response to that video, do the spoilers only stay deployed whilst the wheels are touching the ground. They seem to deploy once the wheels touch then when the plane bounces & is in the air again, they retract :confused:

[Nathan Bartlett]

I would guess that would be the case for if they were to go-around after the first, second (or 5th in this case :D) bounce, you wouldnt want the spoilers to be out when your trying to climb!

[Geoff W]

When did this actually occur?

Kind regards,

Geoff

[Andrew P]

recently as their is a QF A330 parked int he background at Narita

[Erik H. Bakke]

How many takeoff/landing cycles would that count as? :D

[Martin Buzzell]

Video has been deleted :( Wonder who kicked up a stink?

[Grahame Hutchison]

The Captain was probably deleted also.

There is a another video still on there

Yikes. I didn't see the first video, but Nathan's was enough for me.

We've all porpoised a light aeroplane at some stage during our training, but it's never too nice watching a large jet do it. No matter what the aeroplane, the critical thing is to hold the landing (flared) attitude after the bounce, and add power to arrest the ensuing rate of descent. Applying nose-down elevator after a bounce makes for successively harder and higher subsequent bounces and - left unchecked - results in the collapse of the landing gear. Nasty stuff!

Here's what the Boeing's 747-400 Flight Crew Training Manual has to say about bounce recovery:


If the aircraft should bounce, hold or re-establish a normal landing attitude and add thrust as necessary to control the rate of descent. Thrust need not be added for a shallow bounce or skip. When a high, hard bounce occurs, initiate a go-around.

Apply go-around thrust and use normal go-around procedures. Do not retract the landing gear until a positive rate of climb is established because a second
touchdown may occur during the go-around.

Bounced landings can occur because higher than idle power is maintained through initial touchdown, disabling the automatic speedbrake deployment even when the speedbrakes are armed.

There is also another one on there simular to the Korean, this time a JAL 777-300. The video is quite dark but if you got good eyesight you can see a few bounces then eventually going around
