Turn Radius Calculator

The “turn radius” of an aircraft is the radius of the circular path it follows when making a coordinated turn in flight. It’s an important parameter in aircraft design and aviation as it affects an aircraft’s maneuverability and turning performance. The formula for calculating the turn radius of an aircraft during a coordinated level turn is as follows:

• Turn Radius ($R$): Meters (m) or Feet (ft).
• True Airspeed ($V$): Meters per Second (m/s) or Feet per Second (ft/s).
• Acceleration Due to Gravity ($g$): Meters per Second Squared (m/s²) or Feet per Second Squared (ft/s²).
• Bank Angle ($\varphi$): Radians (rad).
