What is the primary effect of increasing True Airspeed (TAS) while maintaining a constant angle of bank during a turn?

Increasing True Airspeed (TAS) while maintaining a constant angle of bank during a turn predominantly results in an increase in both the turn radius and the rate of turn. This relationship stems from the fundamental principles of aerodynamics.

As True Airspeed increases, the centrifugal force acting on the aircraft during the turn also increases. Since the angle of bank is kept constant, the horizontal lift component required to maintain a coordinated turn is greater. To counteract this, the aircraft must bank more steeply to achieve the same amount of turn or, in this case, the turn rate will increase due to the increased airflow over the wings, which enhances lift performance.

Furthermore, with an increase in TAS, the radius of the turn expands. This is a result of the greater speed at which the aircraft is traveling; it covers more distance in a given time frame, thus necessitating a wider radius to maintain the same coordinated turn at the constant bank angle. In essence, the aircraft will experience a larger turn radius due to the increased kinetic energy supplied by the higher airspeed.

This understanding of aerodynamics emphasizes how airspeed influences maneuverability, especially in turning scenarios in flight dynamics.
