: "Bertie the Bunyip" wrote in message ... Doesn't really work all that well with anything, but it's a neccesary evil in some airplanes. High performance fighter jets have to do it and some airliners, especially four engined ones, And most gliders. The issue is ground clearance with those long wings. I was originally a glider pilot and I still have to think ahead and hold my mouth just right before I can slip a power plane all the way down to touchdown. Yep, but the side load matters little in the glider case since you just slide on the grass anyways/ I learned to fly in them too. Bertie |

I just got of the phone with an A320 friend of mine. Demonstrated x-wind as published by Airbus is 35 knots. He reckons Lufty might have that shortened to 33. If it's within limits you take it if you are comfortable. The wind may have veered and or strengthened while he was on approach. That's tkind of th enature of high wind. We try and keep an ear out for the current wind as we're making the aproach.Also, we have several wind displays on board. There'd be a wind arrow on the nav screen with direction and strength, and a digital display breaking it down into head and crosswind components, so the crew can see whan the wind is where they are at any given moment. In short, they knew what the wind was on the runway and it would have been within limits when they shot the approach. Bertie |

Bertie Accuracy from a news report regarding aviation -- no way! Not only did they say it was a 150 MPH crosswind, they also stated that both wings hit the runway. It looks like they did, actually. Looks like he got them both in turn if you watch carefully. There's a stil shot out there of the left most definitely on the ground and if you look at the video the right seems to be touching as he aborts as well. Could be that the right is just raising a little wake in the water, though. Bertie |

Doing a simple Google yielded some historical wind gusts for the
Hamburg area show about 46mph. I'm amazed that the mis information is still being put out there. Yahoo still has it on their homepage. There wasn't even a question that the guys chatting and video taping at the field might have had just a bit of a tough time doing so in 150mph winds? Would a jet make a second attempt in 155mph winds at the same field? This is one of the best examples of media stupidity as it refers to Aviation. Doug |

I don't think so. Not if the numbers were reasonable on approach. Many of the accident reports I've read afterwards gave me a sick "that could have happened to anyone, incuding me" type of feeling, which is what makes them worth reading , of course. Could he have prevented the wing strike by slamming the stick to the right as he was kicking out of the crab? I don't know. The FBW 'Busses are supposed to be able to sort those thngs out themselves. I also guessing Lufthansa's corporate line will be to call him a hero rather than admit that their pilots don't know how to land an airplane. Well, I don't know that he did do anything wrong. My only point in posting the link was to point out that the kick it straight school of landing an airplane is an inferior way of landing an airplane whether it's done by computer or a pilot. The 757 I fly is roughly a similar size and configuration and slipping it onto the runway gives a demonstrated 40 knot x-wind. I've flown in quite nearly that component and it's actually relatively easy. There's enough control authority to keep it straight even in that wind. Bertie |

CNN is reporting that she is onlly 24 years old. Maybe she doesn't have a lot of experience in cross wind landings?? -Robert |
