[NSRCA-discussion] Wind correction

[Adam Glatt]

Cruelly, yes, in a crosswind the entire flight is crooked.  Since seeing 
whether or not you are travelling in or out is very difficult from the 
pilot's perspective, the general approach is to feel the wind, try a 
certain amount of yaw, fly a few maneuvers, and then look to see if you 
have changed flightline distance.  Note that pattern planes are pretty 
good at yawing themselves into the wind - my last plane actually 
yawed/weathervaned itself too much into the wind and had to have some 
downwind rudder held in!  Generally you will establish a weathervane/yaw 
angle with rudder and then only slight rudder input will be required to 
hold it.
