Wind socks
Technically, 'wind socks' are Wind Direction Indicators..........they're intended to provide you with a visual indication of wind direction, and not speed.
The 'Rules of thumb' for estimating wind speed from a dry wind direction indicator is that it's about 15 kts or above if the wind direction indicator appears horizontal, about 10 kts if it's 5 degrees below horizontal, and about 6 kts if it's 30 degrees below horizontal. If it's wet, then wind speeds are going to be a bit higher than for horizontal or the same deflections from horizontal when the wind direction indicator is dry.

Well its all good humour here, but a word of warning to the newbies around the traps, have a good look at the sock, and also your gut feeling from the planes speeds, any smoke etc......because a few socks are in a poor state of repair and can look like they are still when in fact its 20 knots, and probably accross the strip!

Wise words squawk....
I remember seeing three windsocks at Point Cook all pointing about 120 degrees apart from each other!
Also, the speed/dir on the ground may not be the speed/dir at 100 feet+...
