Title: EEK! (somewhat frightening landing photo)
Post by: AmbulanceDriver on October 27, 2013, 12:17:48 PM
Fly320 - I'm guessing this is not standard/correct procedure for putting one of these on the ground......    :O

crosswind

Yup....    The photo caption on flightaware says a gust hit at just the wrong time.   Still a high pucker factor moment if you ask me.......  That little winglet is WAAAAAAAAAAAY too close to the ground for comfort...

I would not have been able to poop for a week after that

I'd be running on empty too after that...

I'm guessing low level shear versus ordinary crosswind.

Okay, well it looked like it could be a "normal" crosswind landing: keeping the upwind wing low and touching down the right main first, to keep from being flipped over.

That is a little too much for a normal crosswind landing. It was probably a gust that caught him.

Still, no damage = no foul.

A good landing is one you can walk away from.  A great landing is one where you can still use the airplane again afterwards.

This actually reminds me of a question I have for you airliner types....    Was flying out of Florianopolis in Brazil a few years back.   I wanna say we were in a 737, but I don't think the type is that important.   We were climbing, and maybe 1000-1500 ft AGL and all the sudden the pilot is trying to pretend this plane is a fighter....   We're basically doing the scissors, but I can't see the plane that's supposed to be attacking us, or the plane we're supposed to be attacking.  All I know is that I'm in the window seat, and one minute I'm seeing nothing but sky, the next nothing but land (and sea).  Then sky.  Then NotSky.   Probably a good 4, maybe 5 times.   While climbing.   And he's pulling enough G that we still feel "down" through our seats more than towards whatever wing he's pointing at the dirt at the moment.

We didn't fly that crazy pattern coming into Florianopolis, and I've never had the opportunity to fly out of there again, but it was bizarre enough that I've tried to find out if there's some kind of terrain clearance or noise abatement thing, but nothing that I can find....

So, was our pilot just a little screwy and missing his days in the Brazilian Air Force?

Had a flight from Florida to New York City in December 1974 that was like that.  Except it was a MAJOR STORM.   Aircraft yawed side to side....ninety degrees<LEVEL>ninety degrees....
A lady a few rows up lost her cookies.   

I was NEVER so happy to get off an airplane!

One of the last times coming home to Billings there was a bad windstorm in Montana.  At first all flights were suspended because of the weather and then they finally decided to take a chance, but telling us we might end up somewhere else instead.

It was really bad curving around into final - the little CRJ was bouncing all over and rolling maybe 30 degrees to each side.  I thought the pilot would abort or else we were going to smash.  At the last few seconds when we got over the edge of the rims, the air smoothed out and we had a normal landing.  =)

For those that don't know, Billings airport is up on top of a hill with cliffs on two sides.  Coming in from the ESE (28?) is almost like landing on a huge carrier: you are still way up in the air and then you come over the edge of the cliff and right onto the runway.

AD, that sounds like wake turbulence from a preceding aircraft.  it can get nasty.  If not that, then probably low level wind shear.  Were you in the mountains?

That tends to happen when the FO slams the rudder back and forth a few times.

here's a google maps view of the airport.  there's some hills to the WSW, and some pretty much due S, but I believe the take off put us right over the channel between the island and the mainland there.

I got sent to Bellingham WA for a crosscountry student flight. Cleared for  final, I was advised a 727 was 10 miles out for landing and would I consider, please, going around so the 727 would not have to. Sure, no problem-I went round and came back too close- about 25 feet off the runway I ran into wake turbulence rough enough that I was bouncing the yoke off the stops, right and left aileron to keep the wingtips from hitting the runway. Just about scared the poo out of me, 'cept I was too busy to crap. =D
 It would have been nice if the tower would have given me a heads up on separation, but on the other I learned a lesson I will never forget!

Serious question: do planes have antilock brakes? What kind of brakes DO they have...hydraulic ones similar to cars? Im trying to get an idea how modulateable they are.

Depends on the plane.  Your basic Cessna or Piper does not have anti-lock, just standard unpowered hydraulics like a motorcycle. 

I'm pretty sure all modern commercial aircraft do have anti-lock brakes.  I know the Airbus family does, although Airbus calls it anti-skid.  They work very well, especially when the plane is light.

The brakes have to be good enough to stop an aircraft at it's maximum weight and maximum takeoff speed without the benefit of reverse thrust.  The brakes are large and have several disks on each wheel.

I've been there. Was riding in the Instructor Pilot's seat (just along for the ride on a refueling mission) in a KC135A model doing a MITO (Minimum Interval Take-off, 15 second interval) in the last ship of a 5 shipper (behind 2 B52H's and 2 more KC's) and we started yawing a lot (I know airplanes can't really fly sideways) but it sure felt like it. I thought I was going to have to have the seat cushion surgically removed from my third point of contact.

Six Flags sure couldn't beat that thrill!

They have air brakes.  [tinfoil]  Seriously I think they have redundant systems....probably hydraulic.

Also they have thrust reversers that direct the engine thrust forward to stop.   They generally do not employ them while actually flying.  :O

Massive electrical failure...?

Somehow I can't help but think "Lucas" whenever I hear that.

Didn't "we" have a couple of problems with the newer high-energy batteries (NiMH, Lithium or something) in aircraft in the past couple of years?

Catching fire or something...?

Yeah....the Li-ion batteries in the Boeing 787s were catching fire. Grounded the fleet until they could come up with a fix.
