Weather vane implies the wind blowing the tail away from and the nose into the
wind which would be desirable for (self)correcting for crosswind. This would
imply that an airplane on a cross country flight would self correct into a
crosswind, no crab necessary. Or the reverse, pilot would have to hold rudder
for a couple of hours on a cross country flight. Talk about a way to induce
asymmetrical leg muscles...wow!<br>
<br>
Rudder is used to point the noise into the wind i.e. to induce crab. Full scale
pilots make a small coordinated turn into the wind to create crab angle and the
desired ground track. I think I read in some pattern stuff that pattern pilots
can induce crab and it either presents better to a judge or they can sneak the
crab in a way not so easily detected by the judge. Weathervaning would
only happen on the ground with a taildragger, usually the beginning of a ground
loop. Or with the airplane on a pylon on the vertical axis, just like a weathervane.<br>
<br>
Crab angle and track apply here. Crosswind acts upon the whole airplane in
flight, not just the tail surface. If we turn this whole situation 90 degrees
and fly into a headwind and pull up, the airplane would flop over on its back
because of the greater exposed surface of the wing area. The wing would have a
greater weathervane effect. But it does not work thataway.<br>
<br>
Bob and I have been having fun with this one for a while.<br>

straighten the plane out to look vertical, the track (actual line drawn) will

has a clip from the rule book covering all parts of this.<br>
