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.

Bank angle (°)

Bank angle of a coordinated level turn.

Compute the load factor in a level turn from the bank angle. 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]

Load factor

Load factor as a multiple of weight.

• 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.

• Stall Speed in Bank Calculator

  Compute the increased stall speed in a level turn from the bank angle.

• Turn Diameter Calculator

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