Sight Distance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sight Distance = (Turning Speed of Aircraft^2)/(25.5*Deceleration)
SD = (V_{Turning Speed}^2)/(25.5*d)
This formula uses 3 Variables

Variables Used

Sight Distance - (Measured in Meter) - Sight Distance is s the minimum distance between two vehicles moving along a curve, when the driver of one vehicle can just see the other vehicle on the road.
Turning Speed of Aircraft - (Measured in Kilometer per Hour) - 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).
Deceleration - (Measured in Square Meter per Second) - Deceleration is defined as the reduction of the speed.

STEP 1: Convert Input(s) to Base Unit

Turning Speed of Aircraft: 50 Kilometer per Hour --> 50 Kilometer per Hour No Conversion Required
Deceleration: 32.6 Square Meter per Second --> 32.6 Square Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

SD = (V_{Turning Speed}^2)/(25.5*d) --> (50^2)/(25.5*32.6)

Evaluating ... ...

SD = 3.00733790448695

STEP 3: Convert Result to Output's Unit

3.00733790448695 Meter --> No Conversion Required

FINAL ANSWER

3.00733790448695 ≈ 3.007338 Meter <-- Sight Distance

Wheelbase given Turning Radius

LaTeX Go Wheelbase = sqrt(((Radius of Curve for Taxiway*(0.5*Taxiway Width))-Distance between Midway Points)/0.388)

Taxiway Width given Turning Radius

LaTeX Go Taxiway Width = (((0.388*Wheelbase^2)/Radius of Curve for Taxiway)+Distance between Midway Points)/0.5

Turning Speed of Aircraft given Radius of Curve

LaTeX Go Turning Speed of Aircraft = sqrt(Radius of Curve for Taxiway*Coefficient of Friction*125)

Turning Radius

LaTeX Go Radius of Curve for Taxiway = (Turning Speed of Aircraft^2)/(125*Coefficient of Friction)

Sight Distance Formula

LaTeX Go

Sight Distance = (Turning Speed of Aircraft^2)/(25.5*Deceleration)
SD = (V_{Turning Speed}^2)/(25.5*d)

What is Sight distance?

Sight distance is the length of roadway visible to a driver. The three types of sight distance common in roadway design are intersection sight distance, stopping sight distance, and passing sight distance.

How to Calculate Sight Distance?
