NWA 757 Go-Around at SEATAC - high winds. VIDEO

[FlyAirtran]

WOW! Guys, nice job on this one. Looks like its time to go to the alternate and clean out our shorts. Watch how abrupt those wings are rocking back and forth. What did the winds get up to yesterday in Seattle?

Nice Work gentleman keeping it under control!

Nice jobs guys!

KSEA winds were gusting to 60 knots at 1AM local. The noon report was 13 gusting to 20 knots. This was a daylight landing so winds should have died down during this video. Lots of rudder and spoiler deflection on both approaches. Good thing it was a Boeing tail.

 

[MED]

Yup, I landed @ exactly 12:00pm, wind died down but the rain starts pouring like a mother.

Nice save Gentleman.

However, if you look carefully, they have absolute lateral control before and after the oscillation begins.

Wasn't there something a few years back about 757's developing a "wing rocking" type event, the cause of which was never found?

757 guys?

[afres bum]

I wonder if this has anything to do with it?

Answered my own question: http://www.flightglobal.com/Article...0/FAA+seeks+to+end+757+roll+oscillations.html


Of course, they always try to blame the Pilots...NOT the aircraft design.


Hmmm...."Mr. Airbus, meet Mr. Boeing. Mr. Boeing, Mr. Airbus."

"Vortex generators can also reduce oscillations, the FAA says. “We have also received flight-test data indicating that one potential cause of these unintended roll oscillations occurs when airflow over the outboard trailing-edge flap separates due to the movement of the spoilers resulting from large control wheel inputs. Abrupt control wheel inputs to counteract the resulting roll can lead to roll oscillations of increasing magnitude.”

Watch the spoilers in the video.

The roll begins, and stops, EXACTLY when they are deployed/stowed.

P.i.o.

 

[Whine Lover]

"P.I.O."

But only as a result of a design flaw which allows the blanketing of the flaps due to spoiler movement.

These guys did a nice job by electing to go-around.

"There but for the Grace of God..."

And how exactly do you know that? Aside from the fact that you're obviously a condescending, conceited, superpilot, know-it-all jacka**?

What did the winds get up to yesterday in Seattle?

According to the Interweb news, 69 MPH @ Seatac, a new record.

Down here in Oregon, I heard two of my neighbor's big pine trees fall down, fortunately in his yard so I don't have to dust off my chainsaw!

I was out at my local aerodrome last night @ 1930 and the wind was strong enough to pick up pebbles off the concrete ramp and throw them -hard- at my windshield.

I went home.

Call us back when you have flown something larger than a 737, ok?

That NW go around was Wednesday. I saw it on the 11pm news Wed night. The winds didn't really kick up until Thursday and Thursday night. Overall a lousy two days for flying.

I wouldn't be surprised if some don't sue for mental anguish or something stupid like that.

 

[bubbers44]

farmin, You are right, yesterdays high winds are not related to the video if the video was taken Wednesday. Take another look at rudder and aileron/spoiler inputs on both approaches. When my copilot insisted it was turbulence causing his problems one day I paid a lot of attention to his inputs and how closely they matched the unstable arrival.

 

[757jetflier]

Had a similar event at MDW a few years ago. I can relate to the situation they were in. Nice job guys!

 

[crjdxr]

Ya just gotta love the 757....

Why don't you pay close attention to this video and note the large trees twisting in the wind. I don't know the exact winds during this landing, but it sure looks strong.

I've got almost 5000 hours in the 757/767 and I'd put good money on that being a PIO. Not placing blame, as wake turbulence, wind gusts, mechanical turbulence, or whatever can cause conditions which require flight control corrections. You can see in the video that the spoilers were really working, so I'm guessing the pilot was really working too. I saw it once shortly after I checked out. I had a couple of rolls and recovered and never let it happen again...these guys just hit the ground first (which recovered them).

 

[starchkr]

You're all wrong, this guy was just showing everyone how maneuverable the 75 is. He touched down on the first approach and went around showing how well he does bounced landings, and his approach was just practice for his future in aerobatics. He was trying to see how fast he could get the thing to roll...pretty good job if you ask me...besides, whats wrong with a little fun on your approaches and landings, kinda boring job if you can't do it every once in awhile.

and crjdxr...that is how you are SUPPOSED to fly an airplane, none of this straight and level crap!!! The lear does that kind of thing well, but the pull up at the end is a bit more abrupt. Ahhhh the days of flyin' freight....but a memory...

Watch the spoilers in the video.

Excellent observation. I'd say the media got it wrong on this one as well.

I wish I had copied the metar, but KBLI (about 60 north of KSEA) baro pressure was 28.98 on Thursday night. Pretty good for a plain old pacific storm.
