Here is how the Field Length equation looks like.

2600 = 2000 + 600

2600m = 2000m + 600m

2600 = 2000 + 600

Field Length Solution

Follow our step by step solution on how to calculate Field Length?

FIRST Step Consider the formula

FL = FS + CL

Next Step Substitute values of Variables

∴

FL = 2000m + 600m

Next Step Prepare to Evaluate

∴

FL = 2000 + 600

LAST Step Evaluate

∴

FL = 2600m

Variables

Field Length

Field Length is defined as the minimum field length required for take-off .

Symbol: FL

Measurement: LengthUnit: m

Note: Value can be positive or negative.

Formulas to find Field Length

Full Strength Pavement Distance

Full Strength Pavement Distance of the runway component.

Symbol: FS

Measurement: LengthUnit: m

Note: Value can be positive or negative.

Formulas to find Full Strength Pavement Distance

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

Other formulas in Normal Takeoff Cases under Estimation of Runway Length category

Go Clearway Distance

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

Go Takeoff Distance given Clearway Distance

TOD = (\frac{CL}{0.5}) + (1.15 \cdot s LO)

Go Lift off Distance given Clearway Distance

s LO = - (\frac{(\frac{CL}{0.5}) - TOD}{1.15})

Go Takeoff Run

T Run = TOD - CL

How to Evaluate Field Length?

Field Length evaluator uses Field Length = Full Strength Pavement Distance+Clearway Distance to evaluate the Field Length, The Field Length is defined as the minimum field length required for take-off at maximum certificated take-off mass, sea level, standard atmospheric conditions, still air and zero runway slope, as shown in the appropriate airplane flight. Field Length is denoted by FL symbol.

How to evaluate Field Length using this online evaluator? To use this online evaluator for Field Length, enter Full Strength Pavement Distance (FS) & Clearway Distance (CL) and hit the calculate button.

FAQs on Field Length

What is the formula to find Field Length?

The formula of Field Length is expressed as Field Length = Full Strength Pavement Distance+Clearway Distance. Here is an example- 2600 = 2000+600.

How to calculate Field Length?

With Full Strength Pavement Distance (FS) & Clearway Distance (CL) we can find Field Length using the formula - Field Length = Full Strength Pavement Distance+Clearway Distance.

Can the Field Length be negative?

Yes, the Field Length, measured in Length can be negative.

Which unit is used to measure Field Length?

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