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.

Inbound leg (min)

Inbound leg time; one minute below 14,000 feet is standard.

Turn rate (°/s)

Turn rate during the holding turns; three degrees per second is standard.

Compute the total time of one complete holding pattern circuit from the inbound leg time and turn rate. 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]

Circuit time (min)

Total time for one full holding circuit.

• 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.

• Final Reserve Fuel Calculator

  Compute the final reserve fuel needed to hold for a given time at the holding burn rate.

• Holding Fuel Required Calculator

  Compute the fuel required to hold for a given time at the expected burn rate.

• Bank Angle for Standard Rate Calculator

  Compute the bank angle that produces a desired turn rate at a given true airspeed.
