when an airplane is already banked left and the controls are neutral, which wing is at a higher angle of attack, the low wing or the high wing. Also what wing will an airplane roll to in a stall?

  1. this cant happen, you cant have a bank left turn and controls neutral.

    the Higher  wing is at a higher angle of attack than the lower  wing becaue of the  difference in aileron deflection.

    In a left banked turn the higher  wing will stall first, but usually not the whole wing, but the wing root, which is favorable because airlions still have some effect.

    correction, had it backwards..


  2. Aircrafts are designed with and envelope of safety/Stability. All types of Aircraft come with diffrent designes on wing). Now most airplanes have a design called a Dihedral (the wing is bent verticaly up or down, mostly up, away from the lateral axis of the airplane, usally 5 degrees on small single engine planes). This Dihedral creates stability Laterally along the longitudinal axis.

    When the Aircraft makes a light bank up to 20 degrees or is disturb by turbulence, the counter happens by rasing the lower wing back to level. The Dihedral will increase the angle of attack on the lower wing in oder to stablize the aircraft.

    Once the Stability angle of bank is exceeded then the Dihedral effect is now beyond its limits. That is true from the first guy, the Aielerons will not be neutral because we are trying to fight of the overbanking tendency with aielerons but that creates adverse yaw forcing you back into the turn, now this is where rudder use comes in.

    (that is why pilot prcatice steep turns, and how to revovery from altitude loss)

    The outer wing now starts to travel faster and create more life (higher angle of attack) than the Dihedral can stabilze therefore causing an over banking tendency.

    As the pilot Pitches up to control altitude loss the pilot only tighten the turns making the wings create more lift and stalling them. The outer wing is at its faster highest angle of attack and the more G-loads on the wing will now stall it from the Inbourd and progress outward. However, before the pilot losses control of the aircraft, he will notifeid of the buffetting or shaking warning him the the wings are about to be fully stalled.

    If you are say doing all this with any Yawing tendencies, P-Factor, Gyroscopic Pre, CorckScrew effect, Torque or Say even a too much rudder (Slip or Skid)  the airplane will spin in the direction of yaw.

    The ingredients for spin is fully stalled wings and some yaw tendecies

  3. Sorry but aileron deflection has nothing to do with the angle of attack.

    the lower wing is seeing a slower airflow over the wing which casuses it to stall first due to the slower air moving over the airfoil ( the wing)

    The aircraft will roll into the lower or slower wing

  4. In a  turn, the outside or upgoing

    wing is meeting the relative wind at a slightly

    higher angle of attack than the lower wing. If

    we pull on the column to the stalling bite,then

    the upgoing wing will reach it first. It will stall

    before the lower wing. The rate at which the

    stick is pulled will dictate the severity of the

    reaction. It can be quite violent.

    The upgoing wing suddenly drops and the

    airplane quickly rolls away from the original

    direction of turn.The nose falls.
