What is the formula to calculate the angle of bank in relation to true airspeed (TAS)?

• A. TAS in knots / 5 + 12
• B. TAS in knots / 10 + 7
• C. TAS in knots / 15 + 8
• D. TAS in knots / 20 + 5

Answer: (B)

The formula to calculate the angle of bank in relation to true airspeed is derived from the need to maintain a specific load factor during a turn. The increase in load factor is managed by adjusting the bank angle, which in turn relates to the true airspeed of the aircraft. The correct choice, which is represented by the formula TAS in knots divided by 10 plus 7, reflects the relationship between the bank angle and the horizontal components of lift, indicating that at higher true airspeeds, a steeper bank angle is necessary to maintain a coordinated turn without increasing the load factor excessively. In this context, dividing the true airspeed by a factor, such as 10, calculates a ratio that scales the angle of bank appropriately for different speeds. The addition of 7 is an adjustment factor based on aerodynamics principles, ensuring that the resultant bank angle remains optimal for performance criteria while maintaining safety during flight operations. This reasoning helps pilots apply the formula effectively during flight planning and execution. Knowing this, it's important to remember that other formulas presented may not align with aerodynamic principles or may not provide an accurate representation for bank angle calculations at varying true airspeeds.
