I Need Help!

If anyone can answer this question with 100% positivity, please let me know...

Current winds at an Airport are  10 degrees @ 25 knots. Which would be the preferred runway for Landing ? 10, 25, 1, or 100. (Also, Please explain how you arrived at your answer)

Ouch... Err, something I can NEVER remember correctly is the exact meaning of the direction of the wind.
I'll assume taht the direction of the wind is where it comes from.
So if the wind comes from a cap of 10 degrees, knowing that you are supposed to land facing the wind, you would have to use the runway 10 logically... unless this runway is too short for your type of plane...
Am I correct ? I'm not sure at all about the wind direction...

The wind is allways the way it is blowing from not to.Check out the link below and it will explain how to read a METAR repart.

And you will want to land and take off from a runway that is facing the wind as much as possiable. so in your case use runway 100 because a 10 degree wind means in order to head into the wind you will have to face allmost due south. Rember the runway number tells you which way you will face so runways 10 and 1 would have you facing allmost due north which means the wind will be behind you not in front of you. For runway 25 you would have a cross wind and have to figure out if there is to much of a tail wind factor. 8-)

I'm lost, but nevertheless I understood some of the stuff you've said :) Thanks for that !
However, I just realized that my previous answer was wrong concerning the number of the runway: I forgot that the last digit of the direction is not written on the runway

Soooo.... the wind comes from 10 degrees cap, that is, almost North (which is 0 degrees, or more commonly, 360 degrees).
You must face the wind to land or takeoff.
So you must take a runway which is facing the wind.
If the wind comes from 10 degrees, you must be on a runway which is as close at 10 degrees as possible. In your case, this is runway 1 (meaning 10 degrees).

What is said above, about using runway 100, is wrong:
- there is no runway 100, only two digits ;)
- maybe you wanted to say "runway 10", which is oriented at 100 degrees, that is almost facing EAST -> this would make you land/takeoff at full crosswinds :/
- you said that you needed a runway heading south... you would go in the same direction as the wind, not facing it. This is dangerous as you would need a much greater landing/takeoff speed.

Facing a wind which comes from 10 degrees direction means using runway 1.

[garymbuska]

Silly me, just goes to show you that it is MONDAY and before Noon I not even awake yet. But you are correct there is no runway with three digits. Runway 1 would have you facing 001 degrees and run way 10 would hve you facing 100 degrees. So you would use 100 unless it was not long enough.

[bowler_man]

Ugh, I'm a little confused. Is it runway 1 you would land at, or what?

[Daube]

Yes, it is runway 1.
Runway 1 is heading 10 degrees just like Runway 25 would be heading 250 degrees.
Runway 36 heads North, runway 18 heads South, runway 9 heads East and runway 27 heads West.

If the wind comes from 10 degrees, you must use the runway which is heading 10 degrees, so that you face the wind. This runway is runway 1.

[Ashton Lawson]

but use any runway anyway, because its good practice for those windy days...

[bowler_man]

Alright guys, thanks a lot!  8-)

Also, if you are at a controlled airport, ATC will direct you to the correct runway.   8-)
