Here is how the Clearway Distance equation looks like.

656.75 = 0.5 \cdot (1900 - (1.15 \cdot 510))

656.75m = 0.5 \cdot (1900m - (1.15 \cdot 510m))

656.75 = 0.5 \cdot (1900 - (1.15 \cdot 510))

Clearway Distance Solution

Follow our step by step solution on how to calculate Clearway Distance?

FIRST Step Consider the formula

CL = 0.5 \cdot (TOD - (1.15 \cdot s LO))

Next Step Substitute values of Variables

∴

CL = 0.5 \cdot (1900m - (1.15 \cdot 510m))

Next Step Prepare to Evaluate

∴

CL = 0.5 \cdot (1900 - (1.15 \cdot 510))

LAST Step Evaluate

∴

CL = 656.75m

Variables

Clearway Distance

Clearway Distance is the difference between takeoff distance available (TODA) and takeoff run available (TORA).

Symbol: CL

Measurement: LengthUnit: m

Note: Value can be positive or negative.

Formulas to find Clearway Distance

Takeoff Distance

Takeoff Distance is the distance from where the vehicle leaves the ground to until it reaches 50 ft (or 15 m).

Symbol: TOD

Measurement: LengthUnit: m

Note: Value can be positive or negative.

Formulas to find Takeoff Distance

Liftoff Distance

Liftoff Distance is the portion of the takeoff procedure during which the airplane is accelerated from a standstill to an airspeed that provides sufficient lift for it to become airborne.

Symbol: s_LO

Measurement: LengthUnit: m

Note: Value should be greater than 0.

How to Evaluate Clearway Distance?

Clearway Distance evaluator uses Clearway Distance = 0.5*(Takeoff Distance-(1.15*Liftoff Distance)) to evaluate the Clearway Distance, The Clearway Distance is the difference between takeoff distance available (TODA) and takeoff run available (TORA). Clearways originate from the end of the takeoff run available. Clearway Distance is denoted by CL symbol.

How to evaluate Clearway Distance using this online evaluator? To use this online evaluator for Clearway Distance, enter Takeoff Distance (TOD) & Liftoff Distance (s_LO) and hit the calculate button.

FAQs on Clearway Distance

What is the formula to find Clearway Distance?

The formula of Clearway Distance is expressed as Clearway Distance = 0.5*(Takeoff Distance-(1.15*Liftoff Distance)). Here is an example- 656.75 = 0.5*(1900-(1.15*510)).

How to calculate Clearway Distance?

With Takeoff Distance (TOD) & Liftoff Distance (s_LO) we can find Clearway Distance using the formula - Clearway Distance = 0.5*(Takeoff Distance-(1.15*Liftoff Distance)).

What are the other ways to Calculate Clearway Distance?

Here are the different ways to Calculate Clearway Distance-

Clearway Distance=Field Length-Full Strength Pavement Distance

Can the Clearway Distance be negative?

Yes, the Clearway Distance, measured in Length can be negative.

Which unit is used to measure Clearway Distance?

Clearway Distance is usually measured using the Meter[m] for Length. Millimeter[m], Kilometer[m], Decimeter[m] are the few other units in which Clearway Distance can be measured.
