shagrat Posted June 25, 2013 Posted June 25, 2013 Only for takeoff and landing. Otherwise, once in the air, the plane couldn't care less what the wind is doing with respect to the ground.correct. I was referencing the start.

Jona33 Posted June 25, 2013 Posted June 25, 2013 ... That's the one. :D Always remember. I don't have a clue what I'm doing
mhe Posted June 25, 2013 Posted June 25, 2013 I think I cracked the problem. The multiple force vectors can be viewed as accelerations instead of speeds. If the acceleration is zero, the applied force is zero too. Therefore angles are not relevant as long as all velocities of both wind and aircraft remain the same. So my mental model only applies if the equilibrium is disturbed, but not if everything remains as it is. Thanks, HugePanic!

311Gryphon Posted June 25, 2013 Posted June 25, 2013 An excellent attitude to have! HugePanic's explanation is quite good I think. As he says, it doesn't matter how strong a steady wind across the ground is, a plane will still be flying straight through the air that surrounds it. The complecation is that during takeoff with a crosswind, for example, this no longer true; the plane is traveling straight along the ground, which may not be in the same direction of the surrounding air. This is when you get weather cocking into the wind, but once airborne, this goes away. So just to help my own understand, we're talking about "weather cocking" here and not "drifting", correct? I was taught that a plane will drift with wind. Thus if you want to travel due north at any given speed but you have a crosswind you would wind up flying slightly "off course" with the wind "pushing" you to your destination. We were given "in flight computers" to use the flight vector and the wind vector to calculate our true speed, flight time, and the heading we needed to make to arrive at our correct destination. Is this correct or am I misunderstanding? http://www.youtube.com/user/311Gryphon i7-8700, 32 GB DDR4 3000, GTX 1080 TI 11GB, 240 GB SSD, 2TB HDD, Dual (sometimes Triple) monitor, TM Warthog HOTAS, Saitek Pro Combat Pedals, TrackIR [sIGPIC][/sIGPIC]
