The crosswind is scary, but so are the undulations in that runway.

Hey! Let’s build a rollercoaster! Nah, let’s make it into an airport instead.

Jesus christ, the winds were so strong some of those planes practically took off while standing still and others seemed to have to kill engines to land......Fu cking sc ary!

I believe the undulations are greatly exaggerated by the focal length of the lens.

The camera had a long lens, which greatly reduced the depth of field and added to that perception. But still: yikes. And it must tear up the tires something awful.

  The telephoto lens exaggerates these, I believe, but that was a lot of good flying by the crews.

I wonder if it’s actually as dangerous as it looks. Is the pilot doing as much man handling of the plane as it would appear? Or is the plane pretty much able to take care of itself, and what we’re seeing is the computer correcting it before anything actually gets hairy?

I thought they looked extremely proficient.

I have no clue. I’m assuming the pilots are doing the work, but who knows?

I don’t know what the capability of airliner auto pilots is these days, but as someone who took flying lessons at a single runway airport, this is something we needed to be able to do manually (didn’t have to deal with anything quite as gusty as in the video though) . Crabbing into the wind isn’t hard at all, the real trick is straightening out at the last minute so that you aren’t landing with your wheels too sideways (we wouldn’t have taken off in weather like this). Turning to face the runway means you will drift sideways and lose a bit of lift (possibly asymmetrically ), so it needs to be done right before touchdown.

Agree - getting the mains down first, and holding the center line is no easy task in those conditions.  Looked like the one Thomas Cook flight came close to a tail strike on rotation, but it could have been exaggerated by the camera.

Looked that way to me as well.

Must be very hard on the tires.

It’s hard on the entire gear structure if the wheels don’t land square with the direction of travel - but the gear on these aircraft are designed to take a certain amount of that.

The real no-no is hitting the nosewheel first - the nose gear is much weaker than the mains, and can easily set up a ‘porpoising’ effect that can get ugly fast.

Porpoising left-right or uo-down with the nose wheel retaining traction?

This is a ‘textbook’ example.  The pilot flared late, and too aggressively, and it just got worse from there.  By about 0:33, the pilot *REALLY* should have initiated a go-around.  By 0:45, the nose gear had collapsed.

Yeah, like, why did he keep trying to land?

What do you call that? Besides a goof-up...

Probably too eager to get the airplane down, and not have to go around and try it again, I suppose.

Note that bounce was higher than the previous one — and the airplane just gets slower and slower with each bounce, too. That is exactly what you would expect - and why you have to go around, or at least add a fair amount of power while holding the nose up if you’re trying to save it.

It’s damn hairy. I’ve been flying since 1995, and have been an instructor since 2001. What you’re seeing is the pilot fighting to keep the nose pointed down the center line while correcting for drift from the almost-perpendicular crosswind. Autopilot isn’t landing the plane in those conditions. A 41kt direct crosswind is no joke, and I’m guessing is close to the max crosswind component allowable. Meaning, any more wind and the rudder doesn’t have the authority to counteract it and the plane lands sideways on the gear. Which is bad. The Bombardier Q400 turboprops always seem to get bounced around the worst in these videos.

Awesome! Thanks for the info. ‘Tis magical to watch :)

Heh. Puke-inducing, to some.
