If an airplane is flying north, from what direction would the wind be blowing to most effectively cause the aircraft to veer toward the east?
• What sort of path would it follow for the first second or so?
answer/question/discussion: ->->->->->->->->->->->-> :
I would say a directional wind of about 300 degrees would help veer the aircraft towards the east. (North is 90 degrees, South is 270). I estimated this by giving the airplane a vector of (10cos90, 10sin90) and then adding vectors representing the wind at different angles. I would then see which resultant vector was the closest to East (0 degrees). It turned out that at 300 degrees, the resultant was the closest I could get it at 15 degrees.
• If the wind keeps shifting so as to remain perpendicular to the direction of motion what path will the airplane follow?
answer/question/discussion: ->->->->->->->->->->->-> :
If the wind was to blow perpendicular to the path of motion, the resultant force would likely be at a 45 degree angle.

Good thinking, but it's actually simpler than that. See the link; no revision necessary.
