How much cross wind is to much cross wind?

[StaTik]

Just landed the 182 in a 18kt cross and it was not fun trying to hit the runway. How much is to much?

That is a question of the aircraft. The maximum demostrated crosswind varries from aircraft to aircraft. Therefore, there is no definitive answer. Plus it would depend on pilot comfort as well. Hope that helps, even though it is a vague answer.

90 degrees to the direction of the runway may be too much. Anything less than that, hey, if you've got the Kahoonas...

Ninety degrees? No problem! As long as the wind speed isn't too strong it doesn't matter. If you do your flying in Oklahoma where 99% of the runways run north-south you don't have much of a choice when you've got a west wind.

Here's the handy 5-7-9 rule to calculate your crosswind component:

If the wind is 30 degrees off the runway heading, multiply the wind speed by 0.5

For a 45 degree angle, multiply wind speed by 0.7.

For a 60 degree angle, multiple wind speed by 0.9.

Obviously, at 90 degrees the crosswind component is equal to the wind speed.

According to the King Schools video "The right stuff" Crosswind landings should be done by banking into the wind, while holding the rudder the opposite direction you bank, as to keep the aircraft lined up with the runway. When you reach your flare, center the ailerons, and land normally. The plane should not slide sidways too much. This was copied out of Flight sim ground school:


[Font size=3]One Wing Low
This sounds like a maneuver invented by
a Chinese flight instructor, doesn’t it? To
use the wing-low method of crosswind
correction, all you need to do is bank the
airplane in the direction of the crosswind.
Use the ailerons to do this. If the wind is
from the right, then add a little right
aileron. This causes the airplane to slip
sideways into the wind, as shown in
Figure 11-4. This is also why the same
method is known as the sideslip method
of crosswind landing. If you bank suffi-ciently,
then the sideways slippage of the
airplane will cancel out the sideways push
of the wind. The result is that the air-plane
tracks down the runway centerline.
There is one additional thing you must do,
however, to make this maneuver work.[/font]

There is also the more complicated "crab" method, which you seem to be doing in your screenshot. One Wing Low is the recomended method however.

[font size="1" color="#FF0000"]LAST EDITED ON Feb-02-02 AT 05:01AM (EDT)[/font][p]I've been doing crosswind landings in real life and have learned a great technique - cross controlled landing configuration.

Basically you use rudder and apply in the direction of the wind until the runway is lined up straight. Then use opposite aileron to prevent the rudder from banking the aircraft. Your controls are cross-controlled, but you'll land in crosswind lined straight up with the runway even in 18 knot crosswind.

EX - If the wind is 18 from 215 and your landing on runway 27, you have a head wind that is blowing you to the right. Turn final and get as lined up as you can. Because of the weathervane effect on the airplane, you need to apply RIGHT rudder (sometimes alot) until the runway is lined up straight. Then correct your approach using left aileron. You should be holding the controls cross controlled the whole approach. It's a tougher way to master but makes landing in crosswinds a whole lot better.

One thing to remember while performing this technique is the cross controlled control surfaces of the aircraft result in a loss of airspeed, therefore an increase in the rate of descent. Watch your airspeed and VS indicator when flying this type of approach. Also cross controlling the plane can induce a spin if airspeed drops to low. You don't want to be spinning on final..you'll meet the ground faster than you like to.

You don't want to crab into the wind all the way down to the runway then try to straighten up at the last second because if you land sideways on your landing gear too hard your tires will last about 2 seconds. Now this is a game, but when flying for real you must land right everytime or go around - no off-field landings in real life and blowing your tires on landing is a sure way to screw yourself outta a flying career!

Enjoy!
