hello!!!

Does anybody have and hints how to land with corsswind - like 40 - 60 miles an hour???
I found some stuff in the FS2004 help... But I'm looking for something more detaild, like guidlines, etc...

I have experienced recently landing in Las Vegas INTL with the wind of 60 mph on B737 what really wasn't nice....  :o

wow 60mph crosswind?
no wonder you can't make it, the max demonstrated crosswind take-off/landing is 35kts - on a DRY runway, 15kts if performing an autoland - for the 737

Wind is not measured in mph in aviation (60mph would be around 51kts) Smiley

But if you do land in crosswind here's the most common technique: The crab crosswind technique

The objective is to maintain wings level thorughout the approach, touchdown and landing roll
On final approach a crab angle is established with wings level to hold the aircraft on the desired course. Application of downwind rudder is started prior to touchdown to eliminate the crab and align the aircraft with the runway centreline.

As rudder is applied, the upwind wing will sweep forward, developing roll. Hold the wings level by application of lateral control into the wind. Touchdown is made with cross control  Smiley

There is also the sideslip technique but it is a bit harder and FS does not simulate it very well at all in larger jets.

Basicly you fly the approach in cross control config. so the aircraft is aligned with the runway centreline during the final phase  of  approach and touchdown.

Trying to land in that kind of a crosswind is like playing russian roulette with 5 bullets Grin
If there is no other runway that air port would close down and not let any one land till the wind dies down
In the real world a pilot would not even dream of landing in that kind of a cross wind.

ok - i know that we measure wind in knots...
anyways thanks for some figures i didnt know...
i was actually wondering what is the strongest wind the airplane can saftly land....
in this case - b373....
it probably dependes on the direction of the wind, etc...

but seriously - the pilot on that great, short flight Reno-Las Vegas informed passenegers about rough landing and said that the wind was 60 miles an hour. maybe it wasnt crosswind.. ??? just the wind... i really dont know.
what i know it wasnt fun and all this was happening like half an hour after a sand storm and airport closer...
take off on A320 wasnt fun either... :)

SO IS IS POSSIBLE that my plane was landing in 60 mph wind???
thanks....

When I was a crew chief on B-52's they had a neat little control called "cross wind crab".  You could point the nose of the 52 (on final) into the wind.....turn the wheels in the direction of the runway and land as pretty as you please!  No Problem!  After the aircraft touched down....the airframe would just twist back to dead center aligned with the runway.  Would be great to have this feature on the "heavies" wouldn't it?  Smiley

By the way 52's can even use it (cross wind crab) on take off.

Every plane has type has a different max cross wind. The cross wind is broken down into head side and tail wind componets and these componets differ from runway to runway. A runway is usually selected based on the amount of head & side wind with no tailwind componet. Each plane type has a thick book that will break down the wind componets for you based on the runway & wind direction.
I use to be a load desk operator for delta air lines at KJAX & had to learn how to manually ballance every type of plane that delta flies, and one of the the things you had to do was to know which runway to take off from. So you had to look in one of many thick books to find the info you needed. 8)
