                       How does the use of aileron to raise a drop-            Aileron Application and Angle of Attack

                    wing? Figure 27 shows how turn-                                                       As the left wing stalls and

                       Your first reaction
                    whenever a wing drops
                    should be to reduce the
                    angle of attack and simul-
