Age 5Explain it to a 5-year-oldStart with a picture

Imagine using Aircraft Coordinated-Turn Radius to answer this question: calculate ideal coordinated-turn radius from true airspeed and gravity-times-bank-tangent acceleration scale? Enter true airspeed and gravity-times-bank-tangent acceleration scale; the calculator shows ideal coordinated-turn radius. For example: true airspeed=72 and gravity-times-bank-tangent acceleration scale=5.663 produce ideal coordinated-turn radius=915.4158573194419. The answer tells you ideal coordinated-turn radius.

Age 15Explain it to a 15-year-oldConnect it to the formula

Ideal level coordinated-turn radius is true airspeed squared divided by gravitational acceleration times tangent of bank angle. This page evaluates the relationship directly. The rule is c=a²/b. Its input values are true airspeed, gravity-times-bank-tangent acceleration scale, and the main result is ideal coordinated-turn radius. For example: true airspeed=72 and gravity-times-bank-tangent acceleration scale=5.663 produce ideal coordinated-turn radius=915.4158573194419.

CollegeExplain it at college levelState the model precisely

This calculator evaluates the stated aircraft coordinated-turn radius relation over the valid real-number domain stated below. The implemented relation is c=a²/b, evaluated from true airspeed, gravity-times-bank-tangent acceleration scale to produce ideal coordinated-turn radius. Ideal level coordinated-turn radius is true airspeed squared divided by gravitational acceleration times tangent of bank angle. This page evaluates the relationship directly. Use true airspeed and a valid nonzero bank angle; wind changes the ground track, while load factor, climb, sideslip, compressibility, and pilot response alter real turns.

Inputs and valid domain

  • true airspeed must be a finite real number.
  • gravity-times-bank-tangent acceleration scale must be a finite real number.

Important boundary: Use true airspeed and a valid nonzero bank angle; wind changes the ground track, while load factor, climb, sideslip, compressibility, and pilot response alter real turns.

The formula

c=a²/b

How the calculator works through it

It substitutes true airspeed, gravity-times-bank-tangent acceleration scale into the formula and exposes every numerical step above. The main output is ideal coordinated-turn radius.

Read the result correctly

The ideal coordinated-turn radius is the direct answer to “calculate ideal coordinated-turn radius from true airspeed and gravity-times-bank-tangent acceleration scale.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.

A worked check

true airspeed=72 and gravity-times-bank-tangent acceleration scale=5.663 produce ideal coordinated-turn radius=915.4158573194419.

Where this model stops being reliable

Use true airspeed and a valid nonzero bank angle; wind changes the ground track, while load factor, climb, sideslip, compressibility, and pilot response alter real turns.

Learn it by changing one value

Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.

Dictionary terms behind this calculator
