rollvinkeln

Rollvinkeln, also known as the bank angle or angle of bank, is a fundamental concept in aerodynamics and aviation. It refers to the angle between the aircraft's lateral axis and the horizontal plane. In simpler terms, it's how much the airplane is tilted sideways.

When an aircraft banks, its lift vector is no longer purely vertical. Instead, it has a vertical component that counteracts gravity and a horizontal component that causes the aircraft to turn. The greater the rollvinkel, the larger the horizontal component of lift, and thus the sharper the turn.

Pilots use the rollvinkel to initiate and control turns. A coordinated turn involves adjusting both the rollvinkel and the rudder to maintain a smooth and stable maneuver without slipping or skidding. The rollvinkel is typically controlled by the ailerons, which are control surfaces located on the trailing edge of the wings. Moving the control column or stick to one side causes the ailerons to deflect, inducing a roll in that direction.

The maximum safe rollvinkel is limited by factors such as the aircraft's structural integrity, the available lift, and aerodynamic considerations like stall. Excessive rollvinkel can lead to a loss of control or structural failure. Understanding and effectively managing the rollvinkel is crucial for safe and efficient flight.
