The simple answer in no.The wind is unreliable.

Answer 5

The problem with this is the direction you want to go and the direction of the wind.

It is a lot like a sailboat.   If you want to to go north and the wind is out of the west, you can adjust sails and rudder and go north.  If you want to go north and the wind is out of the north, it is hard to do.
