Question:

When you are in a slipped stall, why does the airplane roll towards the high wing?

Lets say were in a left banked turn, and using right rudder to preform a coordinated foward slip. Lets say we stalled in this condition, why is it that the airplane will roll towards the high wing?

  1. When the wings stall in 'uncoordinated' flight, the nose moves in the direction of the applied rudder.  It's a pretty simple concept.


  2. Left bank and right rudder isn't a coordinated turn. Most light aircraft will spin in the direction the rudder says. The left aileron will make the right wing be at an even higher angle of attack and left rudder will slow it down. So the drag and rudder will be on the same side. Makes for a very abrupt right stall entry. I hope you are several mistakes high at this point.

  3. First, let's separate turn from a forward slip; they don't belong together. When you stall in a turn you slip toward the low wing as airspeed drops. That puts the outside wing in a wind shadow because the fuselage blocks the flow across that wing. The result is it stalls first and that causes the roll.

    That's a great question; a lot of pilots miss it. And it comes a quite a surprise the first time because you're expecting the opposite. Plus the roll is quite brisk.

    Also it's spooky because it doesn't matter if you  have a  high or low wing machine, it works the same way.

    There are also lots of folks who don't realize the horizontal stabilizer creates negative lift, i.e. down thrust.

    Perform, not preform.

  4. Spanwise airflow.  

    More of that outer, higher wing's air is washing out off the wingtip.  That wing is therefore less efficient, and can stall at a shallower angle of attack.

  5. Becuase the other wingtip is at a higher angle of attack in a forward slip.

    The wingtips will always have different AoAs whenever you're in a slip/skid.

  6. Good question.  Never really thought about that.  Could it be the way the air is over the alerons and hitting the tail?  Still sitting here playing with my hands trying to figure that out?  Interesting, most interesting today!

  7. Think Angle of attack

  8. because that is where most of the weight is being transfered
