Use this calculator for flight-planning study or a first-pass cross-check when all inputs describe the same aircraft, atmospheric condition, and phase of flight.

Turn rate (°/s)

Desired turn rate; three degrees per second is the standard rate.

TAS (kt)

True airspeed.

Compute the bank angle that produces a desired turn rate at a given true airspeed. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Bank angle (°)

Required bank angle.

• Do not use a generic calculator in place of the current aircraft flight manual, approved performance data, operating limitations, NOTAMs, weather, or regulations. Real performance changes with configuration, runway condition, altitude, temperature, wind, loading, and technique.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Cross-check the result against the aircraft flight manual or approved planning system, then apply the required safety margins. Keep signed wind, heading, altitude, speed, and fuel conventions explicit.

• Bank Angle From Load Factor Calculator

  Compute the bank angle that produces a given load factor in a coordinated level turn.

• Rate of Turn Calculator

  Compute the rate of turn in degrees per second from true airspeed and bank angle.

• Turn Diameter Calculator

  Compute the full diameter of a coordinated level turn from true airspeed and bank angle.
