All About Ailerons

Last month in this space we tackled “Proper Rudder Use,” pointing out that in many situations involving angles of attack (AoA) at or near the stall, rudder and not aileron should be the control used to maintain both heading and a wings-level attitude. We also explored how rudder is used to compensate for adverse yaw, and presented a simple exercise pilots can use to demonstrate both its proper and improper application.

Key Takeaways:

  • Ailerons generate lift by changing a wing's angle of attack, but simultaneously create drag that causes adverse yaw, which must be countered with rudder for coordinated flight.
  • At high angles of attack or near a stall, using ailerons to correct a wing drop can induce a stall/spin; instead, opposite rudder should be applied.
  • Properly initiating a coordinated turn typically follows the "RAE" sequence (Rudder, Aileron, Elevator), applying rudder first to counter adverse yaw, followed by aileron for bank, and elevator for pitch to maintain altitude.

Of course, any complete discussion of how to use an airplane’s rudder must also include ailerons and the how and why of their workings, how they create adverse yaw and how we use rudder to maintain coordinated flight. Finally, we want to address an age-old question: Which to apply first when rolling into a banked turn: Rudder? Aileron? Both? Why?
