Key Takeaways Ailerons control the aircrafts roll by adjusting lift on each wing. Adverse yaw is a side effect of aileron use, countered by rudder input. The aircrafts wing is able to generate lift due to its shape. Why does this increase the lift? If the flow on both sides is symmetrical, the wing wont produce any lift.
PARE: Power idle, Ailerons neutral, Rudder opposite, Elevator forward. An aft center of gravity increases flat spin risk. A flat spin happens when the center of gravity shifts too far aft (toward the tail), and the aircraft’s rotation becomes more horizontal. Rudder: Full opposite input to the spin direction.
Lift is the force that aircraft use to counter gravity. Newton’s Third Law is one of the key laws of physics that explains lift. Lets see what Newtons Third Law is, and why we need it to understand lift. This principle is fundamental in generating lift, thrust, and maneuverability, allowing aircraft to fly.
The outer wing generates more lift than the inner wing since it’s temporarily moving faster. Extra lift makes the wing rise. Increased lift on the raised wing immediately creates more induced drag. Placing the center of gravity ahead of the aircraft’s center of lift improves longitudinal stability.
Your ailerons and rudder will be neutral once you’re in the crab position. We use the rudder to align the aircraft’s longitudinal axis with the centerline. Simultaneously, we apply ailerons opposite the rudder input. The pilot needs to hold aileron and rudder deflection the entire time.
These enhancements, along with an increased center of gravity adjustment through the addition of forward ballast, ensured that the Sunderland could effectively defend itself while maintaining balance during flight. The nose turret, initially equipped with a Vickers K machine gun, was later switched to a Browning machine gun.
The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance. An elegantly simple rope system inside the fuselage raises and lowers the Gweduck’s water rudder mounted inside the base of the main rudder (right).
