Turning Radius Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radius of Curve for Taxiway = (Turning Speed of Aircraft^2)/(125*Coefficient of Friction)
R_Taxiway = (V_{Turning Speed}^2)/(125*μ_Friction)
This formula uses 3 Variables

Variables Used

Radius of Curve for Taxiway - (Measured in Meter) - Radius of Curve for Taxiway is the radius of a circle whose part, say, arc is taken for consideration.
Turning Speed of Aircraft - (Measured in Meter per Second) - Turning Speed of Aircraft at the exit taxiway. Aircraft maneuvering is referenced to a standard rate turn, also known as a rate one turn (ROT).
Coefficient of Friction - The Coefficient of Friction (μ) is the ratio defining the force that resists the motion of one body in relation to another body in contact with it.

STEP 1: Convert Input(s) to Base Unit

Turning Speed of Aircraft: 50 Kilometer per Hour --> 13.8888888888889 Meter per Second (Check conversion here)
Coefficient of Friction: 0.2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_Taxiway = (V_{Turning Speed}^2)/(125*μ_Friction) --> (13.8888888888889^2)/(125*0.2)

Evaluating ... ...

R_Taxiway = 7.71604938271606

STEP 3: Convert Result to Output's Unit

7.71604938271606 Meter --> No Conversion Required

FINAL ANSWER

7.71604938271606 ≈ 7.716049 Meter <-- Radius of Curve for Taxiway

What is Lift Force?

Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air. Because lift is a force, it is a vector quantity, having both a magnitude and a direction associated with it.
